+:::{note}
+1. For `sdmgr_novisual`, images are not needed for training and testing. So fake `img_prefix` can be used in configs. As well, fake `file_name` can be used in annotation files.

+
+:::{note}
+1. In the case of openset, the number of node categories is unknown or unfixed, and more node category can be added.
+2. To show that our method can handle openset problem, we modify the ground truth of `WildReceipt` to `WildReceiptOpenset`. The `nodes` are just classified into 4 classes: `background, key, value, others`, while adding `edge` labels for each box.
+3. The model is used to predict whether two nodes are a pair connecting by a valid edge.
+4. You can learn more about the key differences between CloseSet and OpenSet annotations in our [tutorial](tutorials/kie_closeset_openset.md).

+
+>[Bert: Pre-training of deep bidirectional transformers for language understanding](https://arxiv.org/abs/1810.04805)
+
+
+
+## Abstract
+
+We introduce a new language representation model called BERT, which stands for Bidirectional Encoder Representations from Transformers. Unlike recent language representation models, BERT is designed to pre-train deep bidirectional representations from unlabeled text by jointly conditioning on both left and right context in all layers. As a result, the pre-trained BERT model can be fine-tuned with just one additional output layer to create state-of-the-art models for a wide range of tasks, such as question answering and language inference, without substantial task-specific architecture modifications.
+BERT is conceptually simple and empirically powerful. It obtains new state-of-the-art results on eleven natural language processing tasks, including pushing the GLUE score to 80.5% (7.7% point absolute improvement), MultiNLI accuracy to 86.7% (4.6% absolute improvement), SQuAD v1.1 question answering Test F1 to 93.2 (1.5 point absolute improvement) and SQuAD v2.0 Test F1 to 83.1 (5.1 point absolute improvement).

+# DBNet
+
+> [Real-time Scene Text Detection with Differentiable Binarization](https://arxiv.org/abs/1911.08947)
+
+
+## Abstract
+
+Recently, segmentation-based methods are quite popular in scene text detection, as the segmentation results can more accurately describe scene text of various shapes such as curve text. However, the post-processing of binarization is essential for segmentation-based detection, which converts probability maps produced by a segmentation method into bounding boxes/regions of text. In this paper, we propose a module named Differentiable Binarization (DB), which can perform the binarization process in a segmentation network. Optimized along with a DB module, a segmentation network can adaptively set the thresholds for binarization, which not only simplifies the post-processing but also enhances the performance of text detection. Based on a simple segmentation network, we validate the performance improvements of DB on five benchmark datasets, which consistently achieves state-of-the-art results, in terms of both detection accuracy and speed. In particular, with a light-weight backbone, the performance improvements by DB are significant so that we can look for an ideal tradeoff between detection accuracy and efficiency. Specifically, with a backbone of ResNet-18, our detector achieves an F-measure of 82.8, running at 62 FPS, on the MSRA-TD500 dataset.

+# DRRG
+
+> [Deep relational reasoning graph network for arbitrary shape text detection](https://arxiv.org/abs/2003.07493)
+
+
+
+## Abstract
+Arbitrary shape text detection is a challenging task due to the high variety and complexity of scenes texts. In this paper, we propose a novel unified relational reasoning graph network for arbitrary shape text detection. In our method, an innovative local graph bridges a text proposal model via Convolutional Neural Network (CNN) and a deep relational reasoning network via Graph Convolutional Network (GCN), making our network end-to-end trainable. To be concrete, every text instance will be divided into a series of small rectangular components, and the geometry attributes (e.g., height, width, and orientation) of the small components will be estimated by our text proposal model. Given the geometry attributes, the local graph construction model can roughly establish linkages between different text components. For further reasoning and deducing the likelihood of linkages between the component and its neighbors, we adopt a graph-based network to perform deep relational reasoning on local graphs. Experiments on public available datasets demonstrate the state-of-the-art performance of our method.

+We've upgraded our IoU backend from `Polygon3` to `shapely`. There are some performance differences for some models due to the backends' different logics to handle invalid polygons (more info [here](https://github.com/open-mmlab/mmocr/issues/465)). **New evaluation result is presented in brackets** and new logs will be uploaded soon.

+# FCENet
+
+> [Fourier Contour Embedding for Arbitrary-Shaped Text Detection](https://arxiv.org/abs/2104.10442)
+
+
+
+## Abstract
+
+One of the main challenges for arbitrary-shaped text detection is to design a good text instance representation that allows networks to learn diverse text geometry variances. Most of existing methods model text instances in image spatial domain via masks or contour point sequences in the Cartesian or the polar coordinate system. However, the mask representation might lead to expensive post-processing, while the point sequence one may have limited capability to model texts with highly-curved shapes. To tackle these problems, we model text instances in the Fourier domain and propose one novel Fourier Contour Embedding (FCE) method to represent arbitrary shaped text contours as compact signatures. We further construct FCENet with a backbone, feature pyramid networks (FPN) and a simple post-processing with the Inverse Fourier Transformation (IFT) and Non-Maximum Suppression (NMS). Different from previous methods, FCENet first predicts compact Fourier signatures of text instances, and then reconstructs text contours via IFT and NMS during test. Extensive experiments demonstrate that FCE is accurate and robust to fit contours of scene texts even with highly-curved shapes, and also validate the effectiveness and the good generalization of FCENet for arbitrary-shaped text detection. Furthermore, experimental results show that our FCENet is superior to the state-of-the-art (SOTA) methods on CTW1500 and Total-Text, especially on challenging highly-curved text subset.

+
+
+## Abstract
+We present a conceptually simple, flexible, and general framework for object instance segmentation. Our approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation mask for each instance. The method, called Mask R-CNN, extends Faster R-CNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition. Mask R-CNN is simple to train and adds only a small overhead to Faster R-CNN, running at 5 fps. Moreover, Mask R-CNN is easy to generalize to other tasks, e.g., allowing us to estimate human poses in the same framework. We show top results in all three tracks of the COCO suite of challenges, including instance segmentation, bounding-box object detection, and person keypoint detection. Without bells and whistles, Mask R-CNN outperforms all existing, single-model entries on every task, including the COCO 2016 challenge winners. We hope our simple and effective approach will serve as a solid baseline and help ease future research in instance-level recognition.

+# PANet
+
+> [Efficient and Accurate Arbitrary-Shaped Text Detection with Pixel Aggregation Network](https://arxiv.org/abs/1908.05900)
+
+
+
+## Abstract
+
+Scene text detection, an important step of scene text reading systems, has witnessed rapid development with convolutional neural networks. Nonetheless, two main challenges still exist and hamper its deployment to real-world applications. The first problem is the trade-off between speed and accuracy. The second one is to model the arbitrary-shaped text instance. Recently, some methods have been proposed to tackle arbitrary-shaped text detection, but they rarely take the speed of the entire pipeline into consideration, which may fall short in practical this http URL this paper, we propose an efficient and accurate arbitrary-shaped text detector, termed Pixel Aggregation Network (PAN), which is equipped with a low computational-cost segmentation head and a learnable post-processing. More specifically, the segmentation head is made up of Feature Pyramid Enhancement Module (FPEM) and Feature Fusion Module (FFM). FPEM is a cascadable U-shaped module, which can introduce multi-level information to guide the better segmentation. FFM can gather the features given by the FPEMs of different depths into a final feature for segmentation. The learnable post-processing is implemented by Pixel Aggregation (PA), which can precisely aggregate text pixels by predicted similarity vectors. Experiments on several standard benchmarks validate the superiority of the proposed PAN. It is worth noting that our method can achieve a competitive F-measure of 79.9% at 84.2 FPS on CTW1500.

+:::{note}
+We've upgraded our IoU backend from `Polygon3` to `shapely`. There are some performance differences for some models due to the backends' different logics to handle invalid polygons (more info [here](https://github.com/open-mmlab/mmocr/issues/465)). **New evaluation result is presented in brackets** and new logs will be uploaded soon.

+# PSENet
+
+>[Shape robust text detection with progressive scale expansion network](https://arxiv.org/abs/1903.12473)
+
+
+
+## Abstract
+
+Scene text detection has witnessed rapid progress especially with the recent development of convolutional neural networks. However, there still exists two challenges which prevent the algorithm into industry applications. On the one hand, most of the state-of-art algorithms require quadrangle bounding box which is in-accurate to locate the texts with arbitrary shape. On the other hand, two text instances which are close to each other may lead to a false detection which covers both instances. Traditionally, the segmentation-based approach can relieve the first problem but usually fail to solve the second challenge. To address these two challenges, in this paper, we propose a novel Progressive Scale Expansion Network (PSENet), which can precisely detect text instances with arbitrary shapes. More specifically, PSENet generates the different scale of kernels for each text instance, and gradually expands the minimal scale kernel to the text instance with the complete shape. Due to the fact that there are large geometrical margins among the minimal scale kernels, our method is effective to split the close text instances, making it easier to use segmentation-based methods to detect arbitrary-shaped text instances. Extensive experiments on CTW1500, Total-Text, ICDAR 2015 and ICDAR 2017 MLT validate the effectiveness of PSENet. Notably, on CTW1500, a dataset full of long curve texts, PSENet achieves a F-measure of 74.3% at 27 FPS, and our best F-measure (82.2%) outperforms state-of-art algorithms by 6.6%. The code will be released in the future.

+:::{note}
+We've upgraded our IoU backend from `Polygon3` to `shapely`. There are some performance differences for some models due to the backends' different logics to handle invalid polygons (more info [here](https://github.com/open-mmlab/mmocr/issues/465)). **New evaluation result is presented in brackets** and new logs will be uploaded soon.

+# Textsnake
+
+>[TextSnake: A Flexible Representation for Detecting Text of Arbitrary Shapes](https://arxiv.org/abs/1807.01544)
+
+
+
+## Abstract
+
+Driven by deep neural networks and large scale datasets, scene text detection methods have progressed substantially over the past years, continuously refreshing the performance records on various standard benchmarks. However, limited by the representations (axis-aligned rectangles, rotated rectangles or quadrangles) adopted to describe text, existing methods may fall short when dealing with much more free-form text instances, such as curved text, which are actually very common in real-world scenarios. To tackle this problem, we propose a more flexible representation for scene text, termed as TextSnake, which is able to effectively represent text instances in horizontal, oriented and curved forms. In TextSnake, a text instance is described as a sequence of ordered, overlapping disks centered at symmetric axes, each of which is associated with potentially variable radius and orientation. Such geometry attributes are estimated via a Fully Convolutional Network (FCN) model. In experiments, the text detector based on TextSnake achieves state-of-the-art or comparable performance on Total-Text and SCUT-CTW1500, the two newly published benchmarks with special emphasis on curved text in natural images, as well as the widely-used datasets ICDAR 2015 and MSRA-TD500. Specifically, TextSnake outperforms the baseline on Total-Text by more than 40% in F-measure.

+# ABINet
+
+>[Read Like Humans: Autonomous, Bidirectional and Iterative Language Modeling for Scene Text Recognition](https://arxiv.org/abs/2103.06495)
+
+
+## Abstract
+
+Linguistic knowledge is of great benefit to scene text recognition. However, how to effectively model linguistic rules in end-to-end deep networks remains a research challenge. In this paper, we argue that the limited capacity of language models comes from: 1) implicitly language modeling; 2) unidirectional feature representation; and 3) language model with noise input. Correspondingly, we propose an autonomous, bidirectional and iterative ABINet for scene text recognition. Firstly, the autonomous suggests to block gradient flow between vision and language models to enforce explicitly language modeling. Secondly, a novel bidirectional cloze network (BCN) as the language model is proposed based on bidirectional feature representation. Thirdly, we propose an execution manner of iterative correction for language model which can effectively alleviate the impact of noise input. Additionally, based on the ensemble of iterative predictions, we propose a self-training method which can learn from unlabeled images effectively. Extensive experiments indicate that ABINet has superiority on low-quality images and achieves state-of-the-art results on several mainstream benchmarks. Besides, the ABINet trained with ensemble self-training shows promising improvement in realizing human-level recognition.

+:::{note}
+1. ABINet allows its encoder to run and be trained without decoder and fuser. Its encoder is designed to recognize texts as a stand-alone model and therefore can work as an independent text recognizer. We release it as ABINet-Vision.
+2. Facts about the pretrained model: MMOCR does not have a systematic pipeline to pretrain the language model (LM) yet, thus the weights of LM are converted from [the official pretrained model](https://github.com/FangShancheng/ABINet). The weights of ABINet-Vision are directly used as the vision model of ABINet.
+3. Due to some technical issues, the training process of ABINet was interrupted at the 13th epoch and we resumed it later. Both logs are released for full reference.
+4. The model architecture in the logs looks slightly different from the final released version, since it was refactored afterward. However, both architectures are essentially equivalent.

+>[An end-to-end trainable neural network for image-based sequence recognition and its application to scene text recognition](https://arxiv.org/abs/1507.05717)
+
+
+
+## Abstract
+
+Image-based sequence recognition has been a long-standing research topic in computer vision. In this paper, we investigate the problem of scene text recognition, which is among the most important and challenging tasks in image-based sequence recognition. A novel neural network architecture, which integrates feature extraction, sequence modeling and transcription into a unified framework, is proposed. Compared with previous systems for scene text recognition, the proposed architecture possesses four distinctive properties: (1) It is end-to-end trainable, in contrast to most of the existing algorithms whose components are separately trained and tuned. (2) It naturally handles sequences in arbitrary lengths, involving no character segmentation or horizontal scale normalization. (3) It is not confined to any predefined lexicon and achieves remarkable performances in both lexicon-free and lexicon-based scene text recognition tasks. (4) It generates an effective yet much smaller model, which is more practical for real-world application scenarios. The experiments on standard benchmarks, including the IIIT-5K, Street View Text and ICDAR datasets, demonstrate the superiority of the proposed algorithm over the prior arts. Moreover, the proposed algorithm performs well in the task of image-based music score recognition, which evidently verifies the generality of it.

+
+>[NRTR: A No-Recurrence Sequence-to-Sequence Model For Scene Text Recognition](https://arxiv.org/abs/1806.00926)
+
+
+
+## Abstract
+
+Scene text recognition has attracted a great many researches due to its importance to various applications. Existing methods mainly adopt recurrence or convolution based networks. Though have obtained good performance, these methods still suffer from two limitations: slow training speed due to the internal recurrence of RNNs, and high complexity due to stacked convolutional layers for long-term feature extraction. This paper, for the first time, proposes a no-recurrence sequence-to-sequence text recognizer, named NRTR, that dispenses with recurrences and convolutions entirely. NRTR follows the encoder-decoder paradigm, where the encoder uses stacked self-attention to extract image features, and the decoder applies stacked self-attention to recognize texts based on encoder output. NRTR relies solely on self-attention mechanism thus could be trained with more parallelization and less complexity. Considering scene image has large variation in text and background, we further design a modality-transform block to effectively transform 2D input images to 1D sequences, combined with the encoder to extract more discriminative features. NRTR achieves state-of-the-art or highly competitive performance on both regular and irregular benchmarks, while requires only a small fraction of training time compared to the best model from the literature (at least 8 times faster).

+# RobustScanner
+
+>[RobustScanner: Dynamically Enhancing Positional Clues for Robust Text Recognition](https://arxiv.org/abs/2007.07542)
+
+
+
+## Abstract
+
+The attention-based encoder-decoder framework has recently achieved impressive results for scene text recognition, and many variants have emerged with improvements in recognition quality. However, it performs poorly on contextless texts (e.g., random character sequences) which is unacceptable in most of real application scenarios. In this paper, we first deeply investigate the decoding process of the decoder. We empirically find that a representative character-level sequence decoder utilizes not only context information but also positional information. Contextual information, which the existing approaches heavily rely on, causes the problem of attention drift. To suppress such side-effect, we propose a novel position enhancement branch, and dynamically fuse its outputs with those of the decoder attention module for scene text recognition. Specifically, it contains a position aware module to enable the encoder to output feature vectors encoding their own spatial positions, and an attention module to estimate glimpses using the positional clue (i.e., the current decoding time step) only. The dynamic fusion is conducted for more robust feature via an element-wise gate mechanism. Theoretically, our proposed method, dubbed \emph{RobustScanner}, decodes individual characters with dynamic ratio between context and positional clues, and utilizes more positional ones when the decoding sequences with scarce context, and thus is robust and practical. Empirically, it has achieved new state-of-the-art results on popular regular and irregular text recognition benchmarks while without much performance drop on contextless benchmarks, validating its robustness in both contextual and contextless application scenarios.

+# SAR
+> [Show, Attend and Read: A Simple and Strong Baseline for Irregular Text Recognition](https://arxiv.org/abs/1811.00751)
+
+
+
+## Abstract
+
+Recognizing irregular text in natural scene images is challenging due to the large variance in text appearance, such as curvature, orientation and distortion. Most existing approaches rely heavily on sophisticated model designs and/or extra fine-grained annotations, which, to some extent, increase the difficulty in algorithm implementation and data collection. In this work, we propose an easy-to-implement strong baseline for irregular scene text recognition, using off-the-shelf neural network components and only word-level annotations. It is composed of a 31-layer ResNet, an LSTM-based encoder-decoder framework and a 2-dimensional attention module. Despite its simplicity, the proposed method is robust and achieves state-of-the-art performance on both regular and irregular scene text recognition benchmarks.

+:::{note}
+
+- `R31-1/8-1/4` means the height of feature from backbone is 1/8 of input image, where 1/4 for width.
+- We did not use beam search during decoding.
+- We implemented two kinds of decoder. Namely, `ParallelSARDecoder` and `SequentialSARDecoder`.
+ - `ParallelSARDecoder`: Parallel decoding during training with `LSTM` layer. It would be faster.
+ - `SequentialSARDecoder`: Sequential Decoding during training with `LSTMCell`. It would be easier to understand.
+- For train dataset.
+ - We did not construct distinct data groups (20 groups in [[1]](#1)) to train the model group-by-group since it would render model training too complicated.
+ - Instead, we randomly selected `2.4m` patches from `Syn90k`, `2.4m` from `SynthText` and `1.2m` from `SynthAdd`, and grouped all data together. See [config](https://download.openmmlab.com/mmocr/textrecog/sar/sar_r31_academic.py) for details.
+- We used 48 GPUs with `total_batch_size = 64 * 48` in the experiment above to speedup training, while keeping the `initial lr = 1e-3` unchanged.

+# SATRN
+
+>[On Recognizing Texts of Arbitrary Shapes with 2D Self-Attention](https://arxiv.org/abs/1910.04396)
+
+
+
+## Abstract
+
+Scene text recognition (STR) is the task of recognizing character sequences in natural scenes. While there have been great advances in STR methods, current methods still fail to recognize texts in arbitrary shapes, such as heavily curved or rotated texts, which are abundant in daily life (e.g. restaurant signs, product labels, company logos, etc). This paper introduces a novel architecture to recognizing texts of arbitrary shapes, named Self-Attention Text Recognition Network (SATRN), which is inspired by the Transformer. SATRN utilizes the self-attention mechanism to describe two-dimensional (2D) spatial dependencies of characters in a scene text image. Exploiting the full-graph propagation of self-attention, SATRN can recognize texts with arbitrary arrangements and large inter-character spacing. As a result, SATRN outperforms existing STR models by a large margin of 5.7 pp on average in "irregular text" benchmarks. We provide empirical analyses that illustrate the inner mechanisms and the extent to which the model is applicable (e.g. rotated and multi-line text). We will open-source the code.

+## Abstract
+
+Image-based sequence recognition has been a long-standing research topic in computer vision. In this paper, we investigate the problem of scene text recognition, which is among the most important and challenging tasks in image-based sequence recognition. A novel neural network architecture, which integrates feature extraction, sequence modeling and transcription into a unified framework, is proposed. Compared with previous systems for scene text recognition, the proposed architecture possesses four distinctive properties: (1) It is end-to-end trainable, in contrast to most of the existing algorithms whose components are separately trained and tuned. (2) It naturally handles sequences in arbitrary lengths, involving no character segmentation or horizontal scale normalization. (3) It is not confined to any predefined lexicon and achieves remarkable performances in both lexicon-free and lexicon-based scene text recognition tasks. (4) It generates an effective yet much smaller model, which is more practical for real-world application scenarios. The experiments on standard benchmarks, including the IIIT-5K, Street View Text and ICDAR datasets, demonstrate the superiority of the proposed algorithm over the prior arts. Moreover, the proposed algorithm performs well in the task of image-based music score recognition, which evidently verifies the generality of it.

+ "We now demonstrate how to perform training with an MMOCR recognizer. Since training a full academic dataset is time consuming (usually takes about several hours), we will train on the toy dataset for the SAR text recognition model and visualize the predictions. Text detection and other downstream tasks such as KIE follow similar procedures.\n",
+ "\n",
+ "Training a dataset usually consists of the following steps:\n",
+ "1. Convert the dataset into a format supported by MMOCR (e.g. COCO for text detection). The annotation file can be in either .txt or .lmdb format, depending on the size of the dataset. This step is usually applicable to customized datasets, since the datasets and annotation files we provide are already in supported formats. \n",
+ "2. Modify the config for training. \n",
+ "3. Train the model. \n",
+ "\n",
+ "The toy dataset consisits of ten images as well as annotation files in both txt and lmdb format, which can be found in [ocr_toy_dataset](https://github.com/open-mmlab/mmocr/tree/main/tests/data/toy_dataset). "

+# Demo
+
+We provide an easy-to-use API for the demo and application purpose in [ocr.py](https://github.com/open-mmlab/mmocr/blob/main/mmocr/utils/ocr.py) script.
+
+The API can be called through command line (CL) or by calling it from another python script.
+
+---
+
+## Example 1: Text Detection
+
+
+
+
+
+
+**Instruction:** Perform detection inference on an image with the TextSnake recognition model, export the result in a json file (default) and save the visualization file.
+
+- CL interface:
+
+```shell
+python mmocr/utils/ocr.py demo/demo_text_det.jpg --output demo/det_out.jpg --det TextSnake --recog None --export demo/
+```
+
+- Python interface:
+
+```python
+from mmocr.utils.ocr import MMOCR
+
+# Load models into memory
+ocr = MMOCR(det='TextSnake', recog=None)
+
+# Inference
+results = ocr.readtext('demo/demo_text_det.jpg', output='demo/det_out.jpg', export='demo/')
+```
+
+## Example 2: Text Recognition
+
+
+
+
+
+
+**Instruction:** Perform batched recognition inference on a folder with hundreds of image with the CRNN_TPS recognition model and save the visualization results in another folder.
+*Batch size is set to 10 to prevent out of memory CUDA runtime errors.*
+
+- CL interface:
+
+```shell
+python mmocr/utils/ocr.py %INPUT_FOLDER_PATH% --det None --recog CRNN_TPS --batch-mode --single-batch-size 10 --output %OUPUT_FOLDER_PATH%
+```
+
+- Python interface:
+
+```python
+from mmocr.utils.ocr import MMOCR
+
+# Load models into memory
+ocr = MMOCR(det=None, recog='CRNN_TPS')
+
+# Inference
+results = ocr.readtext(%INPUT_FOLDER_PATH%, output = %OUTPUT_FOLDER_PATH%, batch_mode=True, single_batch_size = 10)
+```
+
+## Example 3: Text Detection + Recognition
+
+
+
+
+
+
+**Instruction:** Perform ocr (det + recog) inference on the demo/demo_text_det.jpg image with the PANet_IC15 (default) detection model and SAR (default) recognition model, print the result in the terminal and show the visualization.
+
+- CL interface:
+
+```shell
+python mmocr/utils/ocr.py demo/demo_text_ocr.jpg --print-result --imshow
+```
+
+:::{note}
+
+When calling the script from the command line, the script assumes configs are saved in the `configs/` folder. User can customize the directory by specifying the value of `config_dir`.
+
+:::
+
+- Python interface:
+
+```python
+from mmocr.utils.ocr import MMOCR
+
+# Load models into memory
+ocr = MMOCR()
+
+# Inference
+results = ocr.readtext('demo/demo_text_ocr.jpg', print_result=True, imshow=True)
+```
+
+---
+
+## Example 4: Text Detection + Recognition + Key Information Extraction
+
+
+
+
+
+
+**Instruction:** Perform end-to-end ocr (det + recog) inference first with PS_CTW detection model and SAR recognition model, then run KIE inference with SDMGR model on the ocr result and show the visualization.
+
+- CL interface:
+
+```shell
+python mmocr/utils/ocr.py demo/demo_kie.jpeg --det PS_CTW --recog SAR --kie SDMGR --print-result --imshow
+```
+
+:::{note}
+
+Note: When calling the script from the command line, the script assumes configs are saved in the `configs/` folder. User can customize the directory by specifying the value of `config_dir`.
+
+:::
+
+- Python interface:
+
+```python
+from mmocr.utils.ocr import MMOCR
+
+# Load models into memory
+ocr = MMOCR(det='PS_CTW', recog='SAR', kie='SDMGR')
+
+# Inference
+results = ocr.readtext('demo/demo_kie.jpeg', print_result=True, imshow=True)
+```
+

+
+## API Arguments
+
+The API has an extensive list of arguments that you can use. The following tables are for the python interface.
+
+**MMOCR():**
+
+| Arguments | Type | Default | Description |
+| -------------- | --------------------- | ------------- | ----------------------------------------------------------- |
+| `det` | see [models](#models) | PANet_IC15 | Text detection algorithm |
+| `recog` | see [models](#models) | SAR | Text recognition algorithm |
+| `kie` [1] | see [models](#models) | None | Key information extraction algorithm |
+| `config_dir` | str | configs/ | Path to the config directory where all the config files are located |
+| `det_config` | str | None | Path to the custom config file of the selected det model |
+| `det_ckpt` | str | None | Path to the custom checkpoint file of the selected det model |
+| `recog_config` | str | None | Path to the custom config file of the selected recog model |
+| `recog_ckpt` | str | None | Path to the custom checkpoint file of the selected recog model |
+| `kie_config` | str | None | Path to the custom config file of the selected kie model |
+| `kie_ckpt` | str | None | Path to the custom checkpoint file of the selected kie model |
+| `device` | str | None | Device used for inference, accepting all allowed strings by `torch.device`. E.g., 'cuda:0' or 'cpu'. |
+
+[1]: `kie` is only effective when both text detection and recognition models are specified.
+
+:::{note}
+
+User can use default pretrained models by specifying `det` and/or `recog`, which is equivalent to specifying their corresponding `*_config` and `*_ckpt`. However, manually specifying `*_config` and `*_ckpt` will always override values set by `det` and/or `recog`. Similar rules also apply to `kie`, `kie_config` and `kie_ckpt`.
+
+:::
+
+### readtext()
+
+| Arguments | Type | Default | Description |
+| ------------------- | ----------------------- | ------------ | ---------------------------------------------------------------------- |
+| `img` | str/list/tuple/np.array | **required** | img, folder path, np array or list/tuple (with img paths or np arrays) |
+| `output` | str | None | Output result visualization - img path or folder path |
+| `batch_mode` | bool | False | Whether use batch mode for inference [1] |
+| `det_batch_size` | int | 0 | Batch size for text detection (0 for max size) |
+| `recog_batch_size` | int | 0 | Batch size for text recognition (0 for max size) |
+| `single_batch_size` | int | 0 | Batch size for only detection or recognition |
+| `export` | str | None | Folder where the results of each image are exported |
+| `export_format` | str | json | Format of the exported result file(s) |
+| `details` | bool | False | Whether include the text boxes coordinates and confidence values |
+| `imshow` | bool | False | Whether to show the result visualization on screen |
+| `print_result` | bool | False | Whether to show the result for each image |
+| `merge` | bool | False | Whether to merge neighboring boxes [2] |
+| `merge_xdist` | float | 20 | The maximum x-axis distance to merge boxes |
+
+[1]: Make sure that the model is compatible with batch mode.
+
+[2]: Only effective when the script is running in det + recog mode.
+
+All arguments are the same for the cli, all you need to do is add 2 hyphens at the beginning of the argument and replace underscores by hyphens.
+(*Example:* `det_batch_size` becomes `--det-batch-size`)
+
+For bool type arguments, putting the argument in the command stores it as true.
+(*Example:* `python mmocr/utils/ocr.py demo/demo_text_det.jpg --batch_mode --print_result`
+means that `batch_mode` and `print_result` are set to `True`)

+
+## Additional info
+
+- To perform det + recog inference (end2end ocr), both the `det` and `recog` arguments must be defined.
+- To perform only detection set the `recog` argument to `None`.
+- To perform only recognition set the `det` argument to `None`.
+- `details` argument only works with end2end ocr.
+- `det_batch_size` and `recog_batch_size` arguments define the number of images you want to forward to the model at the same time. For maximum speed, set this to the highest number you can. The max batch size is limited by the model complexity and the GPU VRAM size.
+
+If you have any suggestions for new features, feel free to open a thread or even PR :)

+# 演示
+
+MMOCR 为示例和应用，以 [ocr.py](https://github.com/open-mmlab/mmocr/blob/main/mmocr/utils/ocr.py) 脚本形式，提供了方便使用的 API。
+
+该 API 可以通过命令行执行，也可以在 python 脚本内调用。
+
+---
+
+## 案例一：文本检测
+
+
+
+
+**注：** 首先，使用 PS_CTW 检测模型和 SAR 识别模型，进行端到端的 ocr （检测+识别）推理，然后对得到的结果，使用 SDMGR 模型提取关键信息（KIE），并展示可视化结果。
+
+- 命令行执行：
+
+```shell
+python mmocr/utils/ocr.py demo/demo_kie.jpeg --det PS_CTW --recog SAR --kie SDMGR --print-result --imshow
+```
+
+:::{note}
+
+当用户从命令行执行脚本时，默认配置文件都会保存在 `configs/` 目录下。用户可以通过指定 `config_dir` 的值来自定义读取配置文件的文件夹。
+
+:::
+
+- Python 调用：
+
+```python
+from mmocr.utils.ocr import MMOCR
+
+# 导入模型到内存
+ocr = MMOCR(det='PS_CTW', recog='SAR', kie='SDMGR')
+
+# 推理
+results = ocr.readtext('demo/demo_kie.jpeg', print_result=True, imshow=True)
+```
+
+---
+
+## API 参数
+
+该 API 有多个可供使用的参数列表。下表是 python 接口的参数。
+
+**MMOCR():**
+
+| 参数 | 类型 | 默认值 | 描述 |
+| -------------- | --------------------- | ------------- | ----------------------------------------------------------- |
+| `det` | 参考 **模型** 章节 | PANet_IC15 | 文本检测算法 |
+| `recog` | 参考 **模型** 章节 | SAR | 文本识别算法 |
+| `kie` [1] | 参考 **模型** 章节 | None | 关键信息提取算法 |
+| `config_dir` | str | configs/ | 用于存放所有配置文件的文件夹路径 |
+| `det_config` | str | None | 指定检测模型的自定义配置文件路径 |
+| `det_ckpt` | str | None | 指定检测模型的自定义参数文件路径 |
+| `recog_config` | str | None | 指定识别模型的自定义配置文件路径 |
+| `recog_ckpt` | str | None | 指定识别模型的自定义参数文件路径 |
+| `kie_config` | str | None | 指定关键信息提取模型的自定义配置路径 |
+| `kie_ckpt` | str | None | 指定关键信息提取的自定义参数文件路径 |
+| `device` | str | None | 推理时使用的设备标识, 支持 `torch.device` 所包含的所有设备字符. 例如, 'cuda:0' 或 'cpu'. |
+
+[1]: `kie` 当且仅当同时指定了文本检测和识别模型时才有效。
+
+:::{note}
+
+mmocr 为了方便使用提供了预置的模型配置和对应的预训练权重，用户可以通过指定 `det` 和/或 `recog` 值来指定使用，这种方法等同于分别单独指定其对应的 `*_config` 和 `*_ckpt`。需要注意的是，手动指定 `*_config` 和 `*_ckpt` 会覆盖 `det` 和/或 `recog` 指定模型预置的配置和权重值。 同理 `kie`， `kie_config` 和 `kie_ckpt` 的参数设定逻辑相同。
+
+:::
+
+### readtext()
+
+| 参数 | 类型 | 默认值 | 描述 |
+| ------------------- | ----------------------- | ------------ | ---------------------------------------------------------------------- |
+| `img` | str/list/tuple/np.array | **必填** | 图像，文件夹路径，np array 或 list/tuple （包含图片路径或 np arrays） |
+| `output` | str | None | 可视化输出结果 - 图片路径或文件夹路径 |
+| `batch_mode` | bool | False | 是否使用批处理模式推理 [1] |
+| `det_batch_size` | int | 0 | 文本检测的批处理大小（设置为 0 则与待推理图片个数相同） |
+| `recog_batch_size` | int | 0 | 文本识别的批处理大小（设置为 0 则与待推理图片个数相同） |
+| `single_batch_size` | int | 0 | 仅用于检测或识别使用的批处理大小 |
+| `export` | str | None | 存放导出图片结果的文件夹 |
+| `export_format` | str | json | 导出的结果文件格式 |
+| `details` | bool | False | 是否包含文本框的坐标和置信度的值 |
+| `imshow` | bool | False | 是否在屏幕展示可视化结果 |
+| `print_result` | bool | False | 是否展示每个图片的结果 |
+| `merge` | bool | False | 是否对相邻框进行合并 [2] |
+| `merge_xdist` | float | 20 | 合并相邻框的最大x-轴距离 |
+
+[1]: `batch_mode` 需确保模型兼容批处理模式（见下表模型是否支持批处理）。
+
+[2]: `merge` 只有同时运行检测+识别模式，参数才有效。
+
+以上所有参数在命令行同样适用，只需要在参数前简单添加两个连接符，并且将下参数中的下划线替换为连接符即可。
+（*例如：* `det_batch_size` 变成了 `--det-batch-size`）
+
+对于布尔类型参数，添加在命令中默认为true。
+（*例如：* `python mmocr/utils/ocr.py demo/demo_text_det.jpg --batch_mode --print_result` 意为 `batch_mode` 和 `print_result` 的参数值设置为 `True`）

+SAR_CN 是唯一支持中文字符识别的模型，并且它需要一个中文字典。以便推理能成功运行，请先从 [这里](https://mmocr.readthedocs.io/en/latest/textrecog_models.html#chinese-dataset) 下载辞典。

+
+## 其他需要注意
+
+- 执行检测+识别的推理（端到端 ocr），需要同时定义 `det` 和 `recog` 参数
+- 如果只需要执行检测，则 `recog` 参数设置为 `None`。
+- 如果只需要执行识别，则 `det` 参数设置为 `None`。
+- `details` 参数仅在端到端的 ocr 模型有效。
+- `det_batch_size` 和 `recog_batch_size` 指定了在同时间传递给模型的图片数量。为了提高推理速度，应该尽可能设置你能设置的最大值。最大的批处理值受模型复杂度和 GPU 的显存大小限制。
+
+如果你对新特性有任何建议，请随时开一个 issue，甚至可以提一个 PR:)

+**Full Changelog**: https://github.com/open-mmlab/mmocr/compare/v0.4.0...v0.4.1
+
+## v0.4.0 (15/12/2021)
+
+### Highlights
+
+1. We release a new text recognition model - [ABINet](https://arxiv.org/pdf/2103.06495.pdf) (CVPR 2021, Oral). With it dedicated model design and useful data augmentation transforms, ABINet can achieve the best performance on irregular text recognition tasks. [Check it out!](https://mmocr.readthedocs.io/en/latest/textrecog_models.html#read-like-humans-autonomous-bidirectional-and-iterative-language-modeling-for-scene-text-recognition)
+2. We are also working hard to fulfill the requests from our community.
+[OpenSet KIE](https://mmocr.readthedocs.io/en/latest/kie_models.html#wildreceiptopenset) is one of the achievement, which extends the application of SDMGR from text node classification to node-pair relation extraction. We also provide
+a demo script to convert WildReceipt to open set domain, though it cannot
+take the full advantage of OpenSet format. For more information, please read our
+[tutorial](https://mmocr.readthedocs.io/en/latest/tutorials/kie_closeset_openset.html).
+3. APIs of models can be exposed through TorchServe. [Docs](https://mmocr.readthedocs.io/en/latest/model_serving.html)
+
+### Breaking Changes & Migration Guide
+
+#### Postprocessor
+
+Some refactoring processes are still going on. For all text detection models, we unified their `decode` implementations into a new module category, `POSTPROCESSOR`, which is responsible for decoding different raw outputs into boundary instances. In all text detection configs, the `text_repr_type` argument in `bbox_head` is deprecated and will be removed in the future release.
+
+**Migration Guide**: Find a similar line from detection model's config:
+```
+text_repr_type=xxx,
+```
+And replace it with
+```
+postprocessor=dict(type='{MODEL_NAME}Postprocessor', text_repr_type=xxx)),
+```
+Take a snippet of PANet's config as an example. Before the change, its config for `bbox_head` looks like:
+```
+ bbox_head=dict(
+ type='PANHead',
+ text_repr_type='poly',
+ in_channels=[128, 128, 128, 128],
+ out_channels=6,
+ loss=dict(type='PANLoss')),
+```
+Afterwards:
+```
+ bbox_head=dict(
+ type='PANHead',
+ in_channels=[128, 128, 128, 128],
+ out_channels=6,
+ loss=dict(type='PANLoss'),
+ postprocessor=dict(type='PANPostprocessor', text_repr_type='poly')),
+```
+There are other postprocessors and each takes different arguments. Interested users can find their interfaces or implementations in `mmocr/models/textdet/postprocess` or through our [api docs](https://mmocr.readthedocs.io/en/latest/api.html#textdet-postprocess).
+
+#### New Config Structure
+
+We reorganized the `configs/` directory by extracting reusable sections into `configs/_base_`. Now the directory tree of `configs/_base_` is organized as follows:
+
+```
+_base_
+├── det_datasets
+├── det_models
+├── det_pipelines
+├── recog_datasets
+├── recog_models
+├── recog_pipelines
+└── schedules
+```
+
+Most of model configs are making full use of base configs now, which makes the overall structural clearer and facilitates fair
+comparison across models. Despite the seemingly significant hierarchical difference, **these changes would not break the backward compatibility** as the names of model configs remain the same.
+

+**Full Changelog**: https://github.com/open-mmlab/mmocr/compare/v0.3.0...0.4.0
+
+## v0.3.0 (25/8/2021)
+
+### Highlights
+1. We add a new text recognition model -- SATRN! Its pretrained checkpoint achieves the best performance over other provided text recognition models. A lighter version of SATRN is also released which can obtain ~98% of the performance of the original model with only 45 MB in size. ([@2793145003](https://github.com/2793145003)) [#405](https://github.com/open-mmlab/mmocr/pull/405)
+2. Improve the demo script, `ocr.py`, which supports applying end-to-end text detection, text recognition and key information extraction models on images with easy-to-use commands. Users can find its full documentation in the demo section. ([@samayala22](https://github.com/samayala22), [@manjrekarom](https://github.com/manjrekarom)) [#371](https://github.com/open-mmlab/mmocr/pull/371), [#386](https://github.com/open-mmlab/mmocr/pull/386), [#400](https://github.com/open-mmlab/mmocr/pull/400), [#374](https://github.com/open-mmlab/mmocr/pull/374), [#428](https://github.com/open-mmlab/mmocr/pull/428)
+3. Our documentation is reorganized into a clearer structure. More useful contents are on the way! [#409](https://github.com/open-mmlab/mmocr/pull/409), [#454](https://github.com/open-mmlab/mmocr/pull/454)
+4. The requirement of `Polygon3` is removed since this project is no longer maintained or distributed. We unified all its references to equivalent substitutions in `shapely` instead. [#448](https://github.com/open-mmlab/mmocr/pull/448)
+
+### Breaking Changes & Migration Guide
+1. Upgrade version requirement of MMDetection to 2.14.0 to avoid bugs [#382](https://github.com/open-mmlab/mmocr/pull/382)
+2. MMOCR now has its own model and layer registries inherited from MMDetection's or MMCV's counterparts. ([#436](https://github.com/open-mmlab/mmocr/pull/436)) The modified hierarchical structure of the model registries are now organized as follows.
+
+```text
+mmcv.MODELS -> mmdet.BACKBONES -> BACKBONES
+mmcv.MODELS -> mmdet.NECKS -> NECKS
+mmcv.MODELS -> mmdet.ROI_EXTRACTORS -> ROI_EXTRACTORS
+mmcv.MODELS -> mmdet.HEADS -> HEADS
+mmcv.MODELS -> mmdet.LOSSES -> LOSSES
+mmcv.MODELS -> mmdet.DETECTORS -> DETECTORS
+mmcv.ACTIVATION_LAYERS -> ACTIVATION_LAYERS
+mmcv.UPSAMPLE_LAYERS -> UPSAMPLE_LAYERS
+```
+
+To migrate your old implementation to our new backend, you need to change the import path of any registries and their corresponding builder functions (including `build_detectors`) from `mmdet.models.builder` to `mmocr.models.builder`. If you have referred to any model or layer of MMDetection or MMCV in your model config, you need to add `mmdet.` or `mmcv.` prefix to its name to inform the model builder of the right namespace to work on.
+
+Interested users may check out [MMCV's tutorial on Registry](https://mmcv.readthedocs.io/en/latest/understand_mmcv/registry.html) for in-depth explanations on its mechanism.

+## Important Note
+
+:::{note}
+**For users who want to train models on CTW1500, ICDAR 2015/2017, and Totaltext dataset,** there might be some images containing orientation info in EXIF data. The default OpenCV
+backend used in MMCV would read them and apply the rotation on the images. However, their gold annotations are made on the raw pixels, and such
+inconsistency results in false examples in the training set. Therefore, users should use `dict(type='LoadImageFromFile', color_type='color_ignore_orientation')` in pipelines to change MMCV's default loading behaviour. (see [DBNet's pipeline config](https://github.com/open-mmlab/mmocr/blob/main/configs/_base_/det_pipelines/dbnet_pipeline.py) for example)
+:::
+

+- TensorRT upsampling operation is a little different from PyTorch. For DBNet and PANet, we suggest replacing upsampling operations with the nearest mode to operations with bilinear mode. [Here](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpem_ffm.py#L33) for PANet, [here](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpn_cat.py#L111) and [here](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpn_cat.py#L121) for DBNet. As is shown in the above table, networks with tag * mean the upsampling mode is changed.
+- Note that changing upsampling mode reduces less performance compared with using the nearest mode. However, the weights of networks are trained through the nearest mode. To pursue the best performance, using bilinear mode for both training and TensorRT deployment is recommended.
+- All ONNX and TensorRT models are evaluated with dynamic shapes on the datasets, and images are preprocessed according to the original config file.
+- This tool is still experimental, and we only support a subset of detection and recognition algorithms for now.

+2. Download *DBNet_r18* detector and *SATRN_small* recognizer models from our [Model Zoo](modelzoo.md), and export them with the following python commands (you may change the paths accordingly):
+
+```bash
+python3.9 ../mmocr/tools/deployment/pytorch2onnx.py --verify --output-file detector.onnx ../mmocr/configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py ./dbnet_r18_fpnc_sbn_1200e_icdar2015_20210329-ba3ab597.pth --dynamic-export det ./sample_big_image_eg_1920x1080.png
+
+python3.9 ../mmocr/tools/deployment/pytorch2onnx.py --opset 14 --verify --output-file recognizer.onnx ../mmocr/configs/textrecog/satrn/satrn_small.py ./satrn_small_20211009-2cf13355.pth recog ./sample_small_image_eg_200x50.png
+```
+
+:::{note}
+- Be aware, while exported `detector.onnx` file is relatively small (about 50 Mb), `recognizer.onnx` is pretty big (more than 600 Mb).
+- *DBNet_r18* can use ONNX opset 11, *SATRN_small* can be exported with opset 14.
+:::
+
+:::{warning}
+Be sure, that verifications of both models are successful - look through the export messages.
+:::
+
+### Example
+Example usage of exported models with C++ is in the code below (don't forget to change paths to \*.onnx files). It's applicable to these two models only, other models have another preprocessing and postprocessing logics.

+# Getting Started
+
+In this guide we will show you some useful commands and familiarize you with MMOCR. We also provide [a notebook](https://github.com/open-mmlab/mmocr/blob/main/demo/MMOCR_Tutorial.ipynb) that can help you get the most out of MMOCR.
+
+## Installation
+
+Check out our [installation guide](install.md) for full steps.
+
+## Dataset Preparation
+
+MMOCR supports numerous datasets which are classified by the type of their corresponding tasks. You may find their preparation steps in these sections: [Detection Datasets](datasets/det.md), [Recognition Datasets](datasets/recog.md), [KIE Datasets](datasets/kie.md) and [NER Datasets](datasets/ner.md).
+
+## Inference with Pretrained Models
+
+You can perform end-to-end OCR on our demo image with one simple line of command:
+
+```shell
+python mmocr/utils/ocr.py demo/demo_text_ocr.jpg --print-result --imshow
+```
+
+Its detection result will be printed out and a new window will pop up with result visualization. More demo and full instructions can be found in [Demo](demo.md).
+
+## Training
+
+### Training with Toy Dataset
+
+We provide a toy dataset under `tests/data` on which you can get a sense of training before the academic dataset is prepared.
+
+For example, to train a text recognition task with `seg` method and toy dataset,
+```shell
+python tools/train.py configs/textrecog/seg/seg_r31_1by16_fpnocr_toy_dataset.py --work-dir seg
+```
+
+To train a text recognition task with `sar` method and toy dataset,
+```shell
+python tools/train.py configs/textrecog/sar/sar_r31_parallel_decoder_toy_dataset.py --work-dir sar
+```
+
+### Training with Academic Dataset
+
+Once you have prepared required academic dataset following our instruction, the only last thing to check is if the model's config points MMOCR to the correct dataset path. Suppose we want to train DBNet on ICDAR 2015, and part of `configs/_base_/det_datasets/icdar2015.py` looks like the following:
+```python
+dataset_type = 'IcdarDataset'
+data_root = 'data/icdar2015'
+train = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_training.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+test = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_test.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+train_list = [train]
+test_list = [test]
+```
+You would need to check if `data/icdar2015` is right. Then you can start training with the command:
+```shell
+python tools/train.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py --work-dir dbnet
+```
+
+You can find full training instructions, explanations and useful training configs in [Training](training.md).
+
+## Testing
+
+Suppose now you have finished the training of DBNet and the latest model has been saved in `dbnet/latest.pth`. You can evaluate its performance on the test set using the `hmean-iou` metric with the following command:
+```shell
+python tools/test.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py dbnet/latest.pth --eval hmean-iou
+```
+
+Evaluating any pretrained model accessible online is also allowed:
+```shell
+python tools/test.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py https://download.openmmlab.com/mmocr/textdet/dbnet/dbnet_r18_fpnc_sbn_1200e_icdar2015_20210329-ba3ab597.pth --eval hmean-iou
+```
+
+More instructions on testing are available in [Testing](testing.md).

+
+## Step-by-Step Installation Instructions
+
+a. Create a Conda virtual environment and activate it.
+
+```shell
+conda create -n open-mmlab python=3.7 -y
+conda activate open-mmlab
+```
+
+b. Install PyTorch and torchvision following the [official instructions](https://pytorch.org/), e.g.,
+
+```shell
+conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch
+```
+
+:::{note}
+Make sure that your compilation CUDA version and runtime CUDA version matches.
+You can check the supported CUDA version for precompiled packages on the [PyTorch website](https://pytorch.org/).
+:::
+
+c. Install [mmcv](https://github.com/open-mmlab/mmcv), we recommend you to install the pre-build mmcv as below.
+
+```shell
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
+```
+
+Please replace ``{cu_version}`` and ``{torch_version}`` in the url with your desired one. For example, to install the latest ``mmcv-full`` with CUDA 11 and PyTorch 1.7.0, use the following command:
+
+```shell
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7.0/index.html
+```
+
+:::{note}
+mmcv-full is only compiled on PyTorch 1.x.0 because the compatibility usually holds between 1.x.0 and 1.x.1. If your PyTorch version is 1.x.1, you can install mmcv-full compiled with PyTorch 1.x.0 and it usually works well.
+
+```bash
+# We can ignore the micro version of PyTorch
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7/index.html
+```
+
+:::
+:::{note}
+
+If it compiles during installation, then please check that the CUDA version and PyTorch version **exactly** matches the version in the `mmcv-full` installation command.
+
+See official [installation guide](https://github.com/open-mmlab/mmcv#installation) for different versions of MMCV compatible to different PyTorch and CUDA versions.
+:::
+
+:::{warning}
+You need to run `pip uninstall mmcv` first if you have `mmcv` installed. If `mmcv` and `mmcv-full` are both installed, there will be `ModuleNotFoundError`.
+:::
+
+d. Install [mmdet](https://github.com/open-mmlab/mmdetection), we recommend you to install the latest `mmdet` with pip.
+See [here](https://pypi.org/project/mmdet/) for different versions of `mmdet`.
+
+```shell
+pip install mmdet
+```
+
+Optionally you can choose to install `mmdet` following the official [installation guide](https://github.com/open-mmlab/mmdetection/blob/master/docs/get_started.md).
+
+e. Clone the MMOCR repository.
+
+```shell
+git clone https://github.com/open-mmlab/mmocr.git
+cd mmocr
+```
+
+f. Install build requirements and then install MMOCR.
+
+```shell
+pip install -r requirements.txt
+pip install -v -e . # or "python setup.py develop"
+export PYTHONPATH=$(pwd):$PYTHONPATH
+```
+
+## Full Set-up Script
+
+Here is the full script for setting up MMOCR with Conda.
+
+```shell
+conda create -n open-mmlab python=3.7 -y
+conda activate open-mmlab
+
+# install latest pytorch prebuilt with the default prebuilt CUDA version (usually the latest)
+conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch
+
+# install the latest mmcv-full
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.6.0/index.html
+
+# install mmdetection
+pip install mmdet
+
+# install mmocr
+git clone https://github.com/open-mmlab/mmocr.git
+cd mmocr
+
+pip install -r requirements.txt
+pip install -v -e . # or "python setup.py develop"
+export PYTHONPATH=$(pwd):$PYTHONPATH
+```
+
+## Another option: Docker Image
+
+We provide a [Dockerfile](https://github.com/open-mmlab/mmocr/blob/master/docker/Dockerfile) to build an image.
+
+```shell
+# build an image with PyTorch 1.6, CUDA 10.1
+docker build -t mmocr docker/
+```
+
+Run it with
+
+```shell
+docker run --gpus all --shm-size=8g -it -v {DATA_DIR}:/mmocr/data mmocr
+```
+
+## Prepare Datasets
+
+It is recommended to symlink the dataset root to `mmocr/data`. Please refer to [datasets.md](datasets.md) to prepare your datasets.
+If your folder structure is different, you may need to change the corresponding paths in config files.
+
+The `mmocr` folder is organized as follows:
+
+```
+├── configs/
+├── demo/
+├── docker/
+├── docs/
+├── LICENSE
+├── mmocr/
+├── README.md
+├── requirements/

+# Model Serving
+
+`MMOCR` provides some utilities that facilitate the model serving process.
+Here is a quick walkthrough of necessary steps that let the models to serve through an API.
+
+## Install TorchServe
+
+You can follow the steps on the [official website](https://github.com/pytorch/serve#install-torchserve-and-torch-model-archiver) to install `TorchServe` and
+`torch-model-archiver`.
+
+## Convert model from MMOCR to TorchServe
+
+We provide a handy tool to convert any `.pth` model into `.mar` model
+for TorchServe.
+
+```shell
+python tools/deployment/mmocr2torchserve.py ${CONFIG_FILE} ${CHECKPOINT_FILE} \
+--output-folder ${MODEL_STORE} \
+--model-name ${MODEL_NAME}
+```
+
+:::{note}
+${MODEL_STORE} needs to be an absolute path to a folder.
+:::
+
+For example:
+
+```shell
+python tools/deployment/mmocr2torchserve.py \
+ configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py \
+ checkpoints/dbnet_r18_fpnc_1200e_icdar2015.pth \
+ --output-folder ./checkpoints \
+ --model-name dbnet
+```
+
+## Start Serving
+
+### From your Local Machine
+
+Getting your models prepared, the next step is to start the service with a one-line command:
+
+```bash
+# To load all the models in ./checkpoints
+torchserve --start --model-store ./checkpoints --models all
+# Or, if you only want one model to serve, say dbnet
+torchserve --start --model-store ./checkpoints --models dbnet=dbnet.mar
+```
+
+Then you can access inference, management and metrics services
+through TorchServe's REST API.
+You can find their usages in [TorchServe REST API](https://github.com/pytorch/serve/blob/master/docs/rest_api.md).
+
+| Service | Address |
+| ------------------- | ----------------------- |
+| Inference | `http://127.0.0.1:8080` |
+| Management | `http://127.0.0.1:8081` |
+| Metrics | `http://127.0.0.1:8082` |
+
+:::{note}
+By default, TorchServe binds port number `8080`, `8081` and `8082` to its services.
+You can change such behavior by modifying and saving the contents below to `config.properties`, and running TorchServe with option `--ts-config config.preperties`.
+
+```bash
+inference_address=http://0.0.0.0:8080
+management_address=http://0.0.0.0:8081
+metrics_address=http://0.0.0.0:8082
+number_of_netty_threads=32
+job_queue_size=1000
+model_store=/home/model-server/model-store
+```
+
+:::
+
+
+### From Docker
+
+A better alternative to serve your models is through Docker. We provide a Dockerfile
+that frees you from those tedious and error-prone environmental setup steps.
+
+#### Build `mmocr-serve` Docker image
+
+```shell
+docker build -t mmocr-serve:latest docker/serve/
+```
+
+#### Run `mmocr-serve` with Docker
+
+In order to run Docker in GPU, you need to install [nvidia-docker](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html); or you can omit the `--gpus` argument for a CPU-only session.
+
+The command below will run `mmocr-serve` with a gpu, bind the ports of `8080` (inference),
+`8081` (management) and `8082` (metrics) from container to `127.0.0.1`, and mount
+the checkpoint folder `./checkpoints` from the host machine to `/home/model-server/model-store`
+of the container. For more information, please check the official docs for [running TorchServe with docker](https://github.com/pytorch/serve/blob/master/docker/README.md#running-torchserve-in-a-production-docker-environment).
+
+```shell
+docker run --rm \
+--cpus 8 \
+--gpus device=0 \
+-p8080:8080 -p8081:8081 -p8082:8082 \
+--mount type=bind,source=`realpath ./checkpoints`,target=/home/model-server/model-store \
+mmocr-serve:latest
+```
+
+:::{note}
+`realpath ./checkpoints` points to the absolute path of "./checkpoints", and you can replace it with the absolute path where you store torchserve models.
+:::
+
+Upon running the docker, you can access inference, management and metrics services
+through TorchServe's REST API.
+You can find their usages in [TorchServe REST API](https://github.com/pytorch/serve/blob/master/docs/rest_api.md).
+
+| Service | Address |
+| ------------------- | ----------------------- |
+| Inference | `http://127.0.0.1:8080` |
+| Management | `http://127.0.0.1:8081` |
+| Metrics | `http://127.0.0.1:8082` |
+
+
+
+## 4. Test deployment
+
+Inference API allows user to post an image to a model and returns the prediction result.
+
+```shell
+curl http://127.0.0.1:8080/predictions/${MODEL_NAME} -T demo/demo_text_det.jpg
+```
+
+For example,
+
+```shell
+curl http://127.0.0.1:8080/predictions/dbnet -T demo/demo_text_det.jpg
+```
+
+For detection models, you should obtain a json with an object named `boundary_result`. Each array inside has float numbers representing x, y
+coordinates of boundary vertices in clockwise order, and the last float number as the
+confidence score.
+
+```json
+{
+ "boundary_result": [
+ [
+ 221.18990004062653,
+ 226.875,
+ 221.18990004062653,
+ 212.625,
+ 244.05868631601334,
+ 212.625,
+ 244.05868631601334,
+ 226.875,
+ 0.80883354575186
+ ]
+ ]
+}
+```
+
+For recognition models, the response should look like:
+
+```json
+{
+ "text": "sier",
+ "score": 0.5247521847486496
+}
+```
+
+And you can use `test_torchserve.py` to compare result of TorchServe and PyTorch by visualizing them.
+
+```shell
+python tools/deployment/test_torchserve.py ${IMAGE_FILE} ${CONFIG_FILE} ${CHECKPOINT_FILE} ${MODEL_NAME}
+[--inference-addr ${INFERENCE_ADDR}] [--device ${DEVICE}]
+```
+
+Example:
+
+```shell
+python tools/deployment/test_torchserve.py \
+ demo/demo_text_det.jpg \
+ configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py \
+ checkpoints/dbnet_r18_fpnc_1200e_icdar2015.pth \
+ dbnet
+```

+# Model Architecture Summary
+
+MMOCR has implemented many models that support various tasks. Depending on the type of tasks, these models have different architectural designs and, therefore, might be a bit confusing for beginners to master. We release a primary design doc to clearly illustrate the basic task-specific architectures and provide quick pointers to docstrings of model components to aid users' understanding.
+
+## Text Detection Models
+
+
+
+
+
+
+The design of text detectors is similar to [SingleStageDetector](https://mmdetection.readthedocs.io/en/latest/api.html#mmdet.models.detectors.SingleStageDetector) in MMDetection. The feature of an image was first extracted by `backbone` (e.g., ResNet), and `neck` further processes raw features into a head-ready format, where the models in MMOCR usually adapt the variants of FPN to extract finer-grained multi-level features. `bbox_head` is the core of text detectors, and its implementation varies in different models.
+
+When training, the output of `bbox_head` is directly fed into the `loss` module, which compares the output with the ground truth and generates a loss dictionary for optimizer's use. When testing, `Postprocessor` converts the outputs from `bbox_head` to bounding boxes, which will be used for evaluation metrics (e.g., hmean-iou) and visualization.

+
+## Text Recognition Models
+
+**Most of** the implemented recognizers use the following architecture:
+
+
+
+
+
+
+`preprocessor` refers to any network that processes images before they are fed to `backbone`. `encoder` encodes images features into a hidden vector, which is then transcribed into text tokens by `decoder`.
+
+The architecture diverges at training and test phases. The loss module returns a dictionary during training. In testing, `converter` is invoked to convert raw features into texts, which are wrapped into a dictionary together with confidence scores. Users can access the dictionary with the `text` and `score` keys to query the recognition result.

+:::
+
+## Key Information Extraction Models
+
+
+
+
+
+
+The architecture of key information extraction (KIE) models is similar to text detection models, except for the extra feature extractor. As a downstream task of OCR, KIE models are required to run with bounding box annotations indicating the locations of text instances, from which an ROI extractor extracts the cropped features for `bbox_head` to discover relations among them.
+
+The output containing edges and nodes information from `bbox_head` is sufficient for test and inference. Computation of loss also relies on such information.

+# Testing
+
+We introduce the way to test pretrained models on datasets here.
+
+## Testing with Single GPU
+
+You can use `tools/test.py` to perform single CPU/GPU inference. For example, to evaluate DBNet on IC15: (You can download pretrained models from [Model Zoo](modelzoo.md)):
+
+```shell
+./tools/dist_test.sh configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py dbnet_r18_fpnc_sbn_1200e_icdar2015_20210329-ba3ab597.pth --eval hmean-iou
+```
+
+And here is the full usage of the script:
+
+```shell
+python tools/test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} [ARGS]
+```
+
+:::{note}
+By default, MMOCR prefers GPU(s) to CPU. If you want to test a model on CPU, please empty `CUDA_VISIBLE_DEVICES` or set it to -1 to make GPU(s) invisible to the program. Note that running CPU tests requires **MMCV >= 1.4.4**.
+
+```bash
+CUDA_VISIBLE_DEVICES= python tools/test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} [ARGS]
+```
+
+:::
+
+
+
+| ARGS | Type | Description |
+| ------------------ | --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `--out` | str | Output result file in pickle format. |
+| `--fuse-conv-bn` | bool | Path to the custom config of the selected det model. |
+| `--format-only` | bool | Format the output results without performing evaluation. It is useful when you want to format the results to a specific format and submit them to the test server. |
+| `--gpu-id` | int | GPU id to use. Only applicable to non-distributed training. |
+| `--eval` | 'hmean-ic13', 'hmean-iou', 'acc' | The evaluation metrics, which depends on the task. For text detection, the metric should be either 'hmean-ic13' or 'hmean-iou'. For text recognition, the metric should be 'acc'. |
+| `--show` | bool | Whether to show results. |
+| `--show-dir` | str | Directory where the output images will be saved. |
+| `--show-score-thr` | float | Score threshold (default: 0.3). |
+| `--gpu-collect` | bool | Whether to use gpu to collect results. |
+| `--tmpdir` | str | The tmp directory used for collecting results from multiple workers, available when gpu-collect is not specified. |
+| `--cfg-options` | str | Override some settings in the used config, the key-value pair in xxx=yyy format will be merged into the config file. If the value to be overwritten is a list, it should be of the form of either key="[a,b]" or key=a,b. The argument also allows nested list/tuple values, e.g. key="[(a,b),(c,d)]". Note that the quotation marks are necessary and that no white space is allowed. |
+| `--eval-options` | str | Custom options for evaluation, the key-value pair in xxx=yyy format will be kwargs for dataset.evaluate() function. |
+| `--launcher` | 'none', 'pytorch', 'slurm', 'mpi' | Options for job launcher. |
+
+
+## Testing with Multiple GPUs
+
+MMOCR implements **distributed** testing with `MMDistributedDataParallel`.
+
+You can use the following command to test a dataset with multiple GPUs.
+
+```shell
+[PORT={PORT}] ./tools/dist_test.sh ${CONFIG_FILE} ${CHECKPOINT_FILE} ${GPU_NUM} [PY_ARGS]
+```
+
+
+| Arguments | Type | Description |
+| --------- | ---- | -------------------------------------------------------------------------------- |
+| `PORT` | int | The master port that will be used by the machine with rank 0. Defaults to 29500. |
+| `PY_ARGS` | str | Arguments to be parsed by `tools/test.py`. |
+
+
+For example,
+
+```shell
+./tools/dist_test.sh configs/example_config.py work_dirs/example_exp/example_model_20200202.pth 1 --eval hmean-iou
+```
+
+## Testing with Slurm
+
+If you run MMOCR on a cluster managed with [Slurm](https://slurm.schedmd.com/), you can use the script `tools/slurm_test.sh`.
+
+
+```shell
+[GPUS=${GPUS}] [GPUS_PER_NODE=${GPUS_PER_NODE}] [SRUN_ARGS=${SRUN_ARGS}] ./tools/slurm_test.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${CHECKPOINT_FILE} [PY_ARGS]
+```
+
+| Arguments | Type | Description |
+| --------------- | ---- | ----------------------------------------------------------------------------------------------------------- |
+| `GPUS` | int | The number of GPUs to be used by this task. Defaults to 8. |
+| `GPUS_PER_NODE` | int | The number of GPUs to be allocated per node. Defaults to 8. |
+| `SRUN_ARGS` | str | Arguments to be parsed by srun. Available options can be found [here](https://slurm.schedmd.com/srun.html). |
+| `PY_ARGS` | str | Arguments to be parsed by `tools/test.py`. |
+
+
+Here is an example of using 8 GPUs to test an example model on the 'dev' partition with job name 'test_job'.
+
+```shell
+GPUS=8 ./tools/slurm_test.sh dev test_job configs/example_config.py work_dirs/example_exp/example_model_20200202.pth --eval hmean-iou
+```
+
+## Batch Testing
+
+By default, MMOCR tests the model image by image. For faster inference, you may change `data.val_dataloader.samples_per_gpu` and `data.test_dataloader.samples_per_gpu` in the config. For example,
+
+```
+data = dict(
+ ...
+ val_dataloader=dict(samples_per_gpu=16),
+ test_dataloader=dict(samples_per_gpu=16),
+ ...
+)
+```
+will test the model with 16 images in a batch.
+
+:::{warning}
+Batch testing may incur performance decrease of the model due to the different behavior of the data preprocessing pipeline.

+# Useful Tools
+
+We provide some useful tools under `mmocr/tools` directory.
+
+## Publish a Model
+
+Before you upload a model to AWS, you may want to
+(1) convert the model weights to CPU tensors, (2) delete the optimizer states and
+(3) compute the hash of the checkpoint file and append the hash id to the filename. These functionalities could be achieved by `tools/publish_model.py`.
+
+```shell
+python tools/publish_model.py ${INPUT_FILENAME} ${OUTPUT_FILENAME}
+```
+
+For example,
+
+```shell
+python tools/publish_model.py work_dirs/psenet/latest.pth psenet_r50_fpnf_sbn_1x_20190801.pth
+```
+
+The final output filename will be `psenet_r50_fpnf_sbn_1x_20190801-{hash id}.pth`.
+
+
+## Convert txt annotation to lmdb format
+Sometimes, loading a large txt annotation file with multiple workers can cause OOM (out of memory) error. You can convert the file into lmdb format using `tools/data/utils/txt2lmdb.py` and use LmdbLoader in your config to avoid this issue.
+```bash
+python tools/data/utils/txt2lmdb.py -i -o
+```
+For example,
+```bash
+python tools/data/utils/txt2lmdb.py -i data/mixture/Syn90k/label.txt -o data/mixture/Syn90k/label.lmdb
+```

+# Training
+
+## Training on a Single GPU
+
+You can use `tools/train.py` to train a model on a single machine with a CPU and optionally a GPU.
+
+Here is the full usage of the script:
+
+```shell
+python tools/train.py ${CONFIG_FILE} [ARGS]
+```
+
+:::{note}
+By default, MMOCR prefers GPU to CPU. If you want to train a model on CPU, please empty `CUDA_VISIBLE_DEVICES` or set it to -1 to make GPU invisible to the program. Note that CPU training requires **MMCV >= 1.4.4**.
+
+```bash
+CUDA_VISIBLE_DEVICES= python tools/train.py ${CONFIG_FILE} [ARGS]

+
+## Training on Multiple GPUs
+
+MMOCR implements **distributed** training with `MMDistributedDataParallel`. (Please refer to [datasets.md](datasets.md) to prepare your datasets)
+
+```shell
+[PORT={PORT}] ./tools/dist_train.sh ${CONFIG_FILE} ${WORK_DIR} ${GPU_NUM} [PY_ARGS]
+```
+
+| Arguments | Type | Description |
+| --------- | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `PORT` | int | The master port that will be used by the machine with rank 0. Defaults to 29500. **Note:** If you are launching multiple distrbuted training jobs on a single machine, you need to specify different ports for each job to avoid port conflicts. |
+| `PY_ARGS` | str | Arguments to be parsed by `tools/train.py`. |
+
+## Training on Multiple Machines
+
+MMOCR relies on torch.distributed package for distributed training. Thus, as a basic usage, one can launch distributed training via PyTorch’s [launch utility](https://pytorch.org/docs/stable/distributed.html#launch-utility).
+
+## Training with Slurm
+
+If you run MMOCR on a cluster managed with [Slurm](https://slurm.schedmd.com/), you can use the script `slurm_train.sh`.
+
+```shell
+[GPUS=${GPUS}] [GPUS_PER_NODE=${GPUS_PER_NODE}] [CPUS_PER_TASK=${CPUS_PER_TASK}] [SRUN_ARGS=${SRUN_ARGS}] ./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${WORK_DIR} [PY_ARGS]

+
+```shell
+./tools/slurm_train.sh dev psenet-ic15 configs/textdet/psenet/psenet_r50_fpnf_sbn_1x_icdar2015.py /nfs/xxxx/psenet-ic15
+```
+
+### Running Multiple Training Jobs on a Single Machine
+
+If you are launching multiple training jobs on a single machine with Slurm, you may need to modify the port in configs to avoid communication conflicts.
+
+For example, in `config1.py`,
+
+```python
+dist_params = dict(backend='nccl', port=29500)
+```
+
+In `config2.py`,
+
+```python
+dist_params = dict(backend='nccl', port=29501)
+```
+
+Then you can launch two jobs with `config1.py` ang `config2.py`.
+
+```shell
+CUDA_VISIBLE_DEVICES=0,1,2,3 GPUS=4 ./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} config1.py ${WORK_DIR}
+CUDA_VISIBLE_DEVICES=4,5,6,7 GPUS=4 ./tools/slurm_train.sh ${PARTITION} ${JOB_NAME} config2.py ${WORK_DIR}
+```
+
+## Commonly Used Training Configs
+
+Here we list some configs that are frequently used during training for quick reference.
+
+```python
+total_epochs = 1200
+data = dict(
+ # Note: User can configure general settings of train, val and test dataloader by specifying them here. However, their values can be overridden in dataloader's config.
+ samples_per_gpu=8, # Batch size per GPU
+ workers_per_gpu=4, # Number of workers to process data for each GPU
+ train_dataloader=dict(samples_per_gpu=10, drop_last=True), # Batch size = 10, workers_per_gpu = 4
+ val_dataloader=dict(samples_per_gpu=6, workers_per_gpu=1), # Batch size = 6, workers_per_gpu = 1
+ test_dataloader=dict(workers_per_gpu=16), # Batch size = 8, workers_per_gpu = 16
+ ...
+)
+# Evaluation
+evaluation = dict(interval=1, by_epoch=True) # Evaluate the model every epoch
+# Saving and Logging
+checkpoint_config = dict(interval=1) # Save a checkpoint every epoch
+log_config = dict(
+ interval=5, # Print out the model's performance every 5 iterations
+ hooks=[
+ dict(type='TextLoggerHook')
+ ])
+# Optimizer
+optimizer = dict(type='SGD', lr=0.02, momentum=0.9, weight_decay=0.0001) # Supports all optimizers in PyTorch and shares the same parameters

+# Learn about Configs
+
+We incorporate modular and inheritance design into our config system, which is convenient to conduct various experiments.
+If you wish to inspect the config file, you may run `python tools/misc/print_config.py /PATH/TO/CONFIG` to see the complete config.
+
+## Modify config through script arguments
+
+When submitting jobs using "tools/train.py" or "tools/test.py", you may specify `--cfg-options` to in-place modify the config.
+
+- Update config keys of dict chains.
+
+ The config options can be specified following the order of the dict keys in the original config.
+ For example, `--cfg-options model.backbone.norm_eval=False` changes the all BN modules in model backbones to `train` mode.
+
+- Update keys inside a list of configs.
+
+ Some config dicts are composed as a list in your config. For example, the training pipeline `data.train.pipeline` is normally a list
+ e.g. `[dict(type='LoadImageFromFile'), ...]`. If you want to change `'LoadImageFromFile'` to `'LoadImageFromNdarry'` in the pipeline,
+ you may specify `--cfg-options data.train.pipeline.0.type=LoadImageFromNdarry`.
+
+- Update values of list/tuples.
+
+ If the value to be updated is a list or a tuple. For example, the config file normally sets `workflow=[('train', 1)]`. If you want to
+ change this key, you may specify `--cfg-options workflow="[(train,1),(val,1)]"`. Note that the quotation mark \" is necessary to
+ support list/tuple data types, and that **NO** white space is allowed inside the quotation marks in the specified value.
+
+## Config Name Style
+
+We follow the below style to name full config files (`configs/TASK/*.py`). Contributors are advised to follow the same style.
+
+```
+{model}_[ARCHITECTURE]_[schedule]_{dataset}.py
+```
+
+`{xxx}` is required field and `[yyy]` is optional.
+
+- `{model}`: model type like `dbnet`, `crnn`, etc.
+- `[ARCHITECTURE]`: expands some invoked modules following the order of data flow, and the content depends on the model framework. The following examples show how it is generally expanded.
+ - For text detection tasks, key information tasks, and SegOCR in text recognition task: `{model}_[backbone]_[neck]_[schedule]_{dataset}.py`
+ - For other text recognition tasks, `{model}_[backbone]_[encoder]_[decoder]_[schedule]_{dataset}.py`
+ Note that `backbone`, `neck`, `encoder`, `decoder` are the names of modules, e.g. `r50`, `fpnocr`, etc.
+- `{schedule}`: training schedule. For instance, `1200e` denotes 1200 epochs.
+- `{dataset}`: dataset. It can either be the name of a dataset (`icdar2015`), or a collection of datasets for brevity (e.g. `academic` usually refers to a common practice in academia, which uses MJSynth + SynthText as training set, and IIIT5K, SVT, IC13, IC15, SVTP and CT80 as test set).
+
+Most configs are composed of basic _primitive_ configs in `configs/_base_`, where each _primitive_ config in different subdirectory has a slightly different name style. We present them as follows.
+
+- det_datasets, recog_datasets: `{dataset_name(s)}_[train|test].py`. If [train|test] is not specified, the config should contain both training and test set.
+
+ There are two exceptions: toy_data.py and seg_toy_data.py. In recog_datasets, the first one works for most while the second one contains character level annotations and works for seg baseline only as of Dec 2021.
+- det_models, recog_models: `{model}_[ARCHITECTURE].py`.
+- det_pipelines, recog_pipelines: `{model}_pipeline.py`.
+- schedules: `schedule_{optimizer}_{num_epochs}e.py`.
+
+## Config Structure
+
+For better config reusability, we break many of reusable sections of configs into `configs/_base_`. Now the directory tree of `configs/_base_` is organized as follows:
+
+```
+_base_
+├── det_datasets
+├── det_models
+├── det_pipelines
+├── recog_datasets
+├── recog_models
+├── recog_pipelines
+└── schedules
+```
+
+These _primitive_ configs are categorized by their roles in a complete config. Most of model configs are making full use of _primitive_ configs by including them as parts of `_base_` section. For example, [dbnet_r18_fpnc_1200e_icdar2015.py](https://github.com/open-mmlab/mmocr/blob/5a8859fe6666c096b75fa44db4f6c53d81a2ed62/configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py) takes five _primitive_ configs from `_base_`:
+
+```python
+_base_ = [
+ '../../_base_/runtime_10e.py',
+ '../../_base_/schedules/schedule_sgd_1200e.py',
+ '../../_base_/det_models/dbnet_r18_fpnc.py',
+ '../../_base_/det_datasets/icdar2015.py',
+ '../../_base_/det_pipelines/dbnet_pipeline.py'
+]
+```
+
+From these configs' names we can roughly know this config trains dbnet_r18_fpnc with sgd optimizer in 1200 epochs. It uses the origin dbnet pipeline and icdar2015 as the dataset. We encourage users to follow and take advantage of this convention to organize the config clearly and facilitate fair comparison across different _primitive_ configurations as well as models.
+
+Please refer to [mmcv](https://mmcv.readthedocs.io/en/latest/understand_mmcv/config.html) for detailed documentation.
+
+## Config File Structure
+
+### Model
+
+The parameter `"model"` is a python dictionary in the configuration file, which mainly includes information such as network structure and loss function.
+
+```{note}
+The 'type' in the configuration file is not a constructed parameter, but a class name.
+```
+
+```{note}
+We can also use models from MMDetection by adding `mmdet.` prefix to type name, or from other OpenMMLab projects in a similar way if their backbones are registered in registries.
+```

+
+### Data & Pipeline
+
+The parameter `"data"` is a python dictionary in the configuration file, which mainly includes information to construct dataloader:
+
+- `samples_per_gpu` : the BatchSize of each GPU when building the dataloader
+- `workers_per_gpu` : the number of threads per GPU when building dataloader
+- `train | val | test` : config to construct dataset
+ - `type`: Dataset name. Check [dataset types](../dataset_types.md) for supported datasets.
+
+The parameter `evaluation` is also a dictionary, which is the configuration information of `evaluation hook`, mainly including evaluation interval, evaluation index, etc.

+
+## FAQ
+
+### Ignore some fields in the base configs
+
+Sometimes, you may set `_delete_=True` to ignore some of fields in base configs.
+You may refer to [mmcv](https://mmcv.readthedocs.io/en/latest/understand_mmcv/config.html#inherit-from-base-config-with-ignored-fields) for simple illustration.
+
+### Use intermediate variables in configs
+
+Some intermediate variables are used in the configs files, like `train_pipeline`/`test_pipeline` in datasets.
+It's worth noting that when modifying intermediate variables in the children configs, user need to pass the intermediate variables into corresponding fields again.
+For example, we usually want the data path to be a variable so that we
+
+```python
+dataset_type = 'IcdarDataset'
+data_root = 'data/icdar2015'
+
+train = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_training.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+
+test = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_test.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+```
+
+### Use some fields in the base configs
+
+Sometimes, you may refer to some fields in the `_base_` config, so as to avoid duplication of definitions. You can refer to [mmcv](https://mmcv.readthedocs.io/en/latest/understand_mmcv/config.html#reference-variables-from-base) for some more instructions.
+
+This technique has been widely used in MMOCR's configs, where the main configs refer to the dataset and pipeline defined in _base_ configs by:
+
+```python
+train_list = {{_base_.train_list}}
+test_list = {{_base_.test_list}}
+
+train_pipeline = {{_base_.train_pipeline}}
+test_pipeline = {{_base_.test_pipeline}}
+```
+
+Which assumes that its _base_ configs export datasets and pipelines in a way like:
+
+```python
+# base dataset config
+dataset_type = 'IcdarDataset'
+data_root = 'data/icdar2015'
+
+train = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_training.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+
+test = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_test.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+
+train_list = [train]
+test_list = [test]
+```
+
+```python
+# base pipeline config
+train_pipeline = dict(...)
+test_pipeline = dict(...)
+```
+
+## Deprecated train_cfg/test_cfg
+
+The `train_cfg` and `test_cfg` are deprecated in config file, please specify them in the model config. The original config structure is as below.
+
+```python
+# deprecated
+model = dict(
+ type=...,
+ ...
+)
+train_cfg=dict(...)
+test_cfg=dict(...)
+```
+
+The migration example is as below.
+
+```python
+# recommended
+model = dict(
+ type=...,
+ ...
+ train_cfg=dict(...),
+ test_cfg=dict(...),
+)

+# Dataset Types
+
+## General Introduction
+
+To support the tasks of text detection, text recognition and key information extraction, we have designed some new types of dataset which consist of **loader** and **parser** to load and parse different types of annotation files.
+- **loader**: Load the annotation file. There are two types of loader, `HardDiskLoader` and `LmdbLoader`
+ - `HardDiskLoader`: Load `txt` format annotation file from hard disk to memory.
+ - `LmdbLoader`: Load `lmdb` format annotation file with lmdb backend, which is very useful for **extremely large** annotation files to avoid out-of-memory problem when ten or more GPUs are used, since each GPU will start multiple processes to load annotation file to memory.
+- **parser**: Parse the annotation file line-by-line and return with `dict` format. There are two types of parser, `LineStrParser` and `LineJsonParser`.
+ - `LineStrParser`: Parse one line in ann file while treating it as a string and separating it to several parts by a `separator`. It can be used on tasks with simple annotation files such as text recognition where each line of the annotation files contains the `filename` and `label` attribute only.
+ - `LineJsonParser`: Parse one line in ann file while treating it as a json-string and using `json.loads` to convert it to `dict`. It can be used on tasks with complex annotation files such as text detection where each line of the annotation files contains multiple attributes (e.g. `filename`, `height`, `width`, `box`, `segmentation`, `iscrowd`, `category_id`, etc.).
+
+Here we show some examples of using different combination of `loader` and `parser`.
+
+## General Task
+
+### UniformConcatDataset
+
+`UniformConcatDataset` is a dataset wrapper which allows users to apply a universal pipeline on multiple datasets without specifying the pipeline for each of them.
+
+For example, to apply `train_pipeline` on both `train1` and `train2`,
+
+```python
+data = dict(
+ ...
+ train=dict(
+ type='UniformConcatDataset',
+ datasets=[train1, train2],
+ pipeline=train_pipeline))
+```
+
+Also, it support apply different `pipeline` to different `datasets`,
+
+```python
+train_list1 = [train1, train2]
+train_list2 = [train3, train4]
+
+data = dict(
+ ...
+ train=dict(
+ type='UniformConcatDataset',
+ datasets=[train_list1, train_list2],
+ pipeline=[train_pipeline1, train_pipeline2]))
+```
+
+Here, `train_pipeline1` will be applied to `train1` and `train2`, and
+`train_pipeline2` will be applied to `train3` and `train4`.
+
+## Text Detection Task
+
+### TextDetDataset
+
+*Dataset with annotation file in line-json txt format*
+
+```python
+dataset_type = 'TextDetDataset'
+img_prefix = 'tests/data/toy_dataset/imgs'
+test_anno_file = 'tests/data/toy_dataset/instances_test.txt'
+test = dict(
+ type=dataset_type,
+ img_prefix=img_prefix,
+ ann_file=test_anno_file,
+ loader=dict(
+ type='HardDiskLoader',
+ repeat=4,
+ parser=dict(
+ type='LineJsonParser',
+ keys=['file_name', 'height', 'width', 'annotations'])),
+ pipeline=test_pipeline,
+ test_mode=True)
+```
+The results are generated in the same way as the segmentation-based text recognition task above.
+You can check the content of the annotation file in `tests/data/toy_dataset/instances_test.txt`.
+The combination of `HardDiskLoader` and `LineJsonParser` will return a dict for each file by calling `__getitem__`:
+```python
+{"file_name": "test/img_10.jpg", "height": 720, "width": 1280, "annotations": [{"iscrowd": 1, "category_id": 1, "bbox": [260.0, 138.0, 24.0, 20.0], "segmentation": [[261, 138, 284, 140, 279, 158, 260, 158]]}, {"iscrowd": 0, "category_id": 1, "bbox": [288.0, 138.0, 129.0, 23.0], "segmentation": [[288, 138, 417, 140, 416, 161, 290, 157]]}, {"iscrowd": 0, "category_id": 1, "bbox": [743.0, 145.0, 37.0, 18.0], "segmentation": [[743, 145, 779, 146, 780, 163, 746, 163]]}, {"iscrowd": 0, "category_id": 1, "bbox": [783.0, 129.0, 50.0, 26.0], "segmentation": [[783, 129, 831, 132, 833, 155, 785, 153]]}, {"iscrowd": 1, "category_id": 1, "bbox": [831.0, 133.0, 43.0, 23.0], "segmentation": [[831, 133, 870, 135, 874, 156, 835, 155]]}, {"iscrowd": 1, "category_id": 1, "bbox": [159.0, 204.0, 72.0, 15.0], "segmentation": [[159, 205, 230, 204, 231, 218, 159, 219]]}, {"iscrowd": 1, "category_id": 1, "bbox": [785.0, 158.0, 75.0, 21.0], "segmentation": [[785, 158, 856, 158, 860, 178, 787, 179]]}, {"iscrowd": 1, "category_id": 1, "bbox": [1011.0, 157.0, 68.0, 16.0], "segmentation": [[1011, 157, 1079, 160, 1076, 173, 1011, 170]]}]}
+```
+
+
+### IcdarDataset
+
+*Dataset with annotation file in coco-like json format*
+
+For text detection, you can also use an annotation file in a COCO format that is defined in [MMDetection](https://github.com/open-mmlab/mmdetection/blob/master/mmdet/datasets/coco.py):
+```python
+dataset_type = 'IcdarDataset'
+prefix = 'tests/data/toy_dataset/'
+test=dict(
+ type=dataset_type,
+ ann_file=prefix + 'instances_test.json',
+ img_prefix=prefix + 'imgs',
+ pipeline=test_pipeline)
+```
+You can check the content of the annotation file in `tests/data/toy_dataset/instances_test.json`.
+
+:::{note}
+Icdar 2015/2017 and ctw1500 annotations need to be converted into the COCO format following the steps in [datasets.md](datasets.md).
+:::
+
+## Text Recognition Task
+
+### OCRDataset
+
+*Dataset for encoder-decoder based recognizer*
+
+```python
+dataset_type = 'OCRDataset'
+img_prefix = 'tests/data/ocr_toy_dataset/imgs'
+train_anno_file = 'tests/data/ocr_toy_dataset/label.txt'
+train = dict(
+ type=dataset_type,
+ img_prefix=img_prefix,
+ ann_file=train_anno_file,
+ loader=dict(
+ type='HardDiskLoader',
+ repeat=10,
+ parser=dict(
+ type='LineStrParser',
+ keys=['filename', 'text'],
+ keys_idx=[0, 1],
+ separator=' ')),
+ pipeline=train_pipeline,
+ test_mode=False)
+```
+You can check the content of the annotation file in `tests/data/ocr_toy_dataset/label.txt`.
+The combination of `HardDiskLoader` and `LineStrParser` will return a dict for each file by calling `__getitem__`: `{'filename': '1223731.jpg', 'text': 'GRAND'}`.
+
+**Optional Arguments:**
+
+- `repeat`: The number of repeated lines in the annotation files. For example, if there are `10` lines in the annotation file, setting `repeat=10` will generate a corresponding annotation file with size `100`.
+
+If the annotation file is extremely large, you can convert it from txt format to lmdb format with the following command:
+```python
+python tools/data_converter/txt2lmdb.py -i ann_file.txt -o ann_file.lmdb
+```
+
+After that, you can use `LmdbLoader` in dataset like below.
+```python
+img_prefix = 'tests/data/ocr_toy_dataset/imgs'
+train_anno_file = 'tests/data/ocr_toy_dataset/label.lmdb'
+train = dict(
+ type=dataset_type,
+ img_prefix=img_prefix,
+ ann_file=train_anno_file,
+ loader=dict(
+ type='LmdbLoader',
+ repeat=10,
+ parser=dict(
+ type='LineStrParser',
+ keys=['filename', 'text'],
+ keys_idx=[0, 1],
+ separator=' ')),
+ pipeline=train_pipeline,
+ test_mode=False)
+```
+
+### OCRSegDataset
+
+*Dataset for segmentation-based recognizer*
+
+```python
+prefix = 'tests/data/ocr_char_ann_toy_dataset/'
+train = dict(
+ type='OCRSegDataset',
+ img_prefix=prefix + 'imgs',
+ ann_file=prefix + 'instances_train.txt',
+ loader=dict(
+ type='HardDiskLoader',
+ repeat=10,
+ parser=dict(
+ type='LineJsonParser',
+ keys=['file_name', 'annotations', 'text'])),
+ pipeline=train_pipeline,
+ test_mode=True)
+```
+You can check the content of the annotation file in `tests/data/ocr_char_ann_toy_dataset/instances_train.txt`.
+The combination of `HardDiskLoader` and `LineJsonParser` will return a dict for each file by calling `__getitem__` each time:
+```python
+{"file_name": "resort_88_101_1.png", "annotations": [{"char_text": "F", "char_box": [11.0, 0.0, 22.0, 0.0, 12.0, 12.0, 0.0, 12.0]}, {"char_text": "r", "char_box": [23.0, 2.0, 31.0, 1.0, 24.0, 11.0, 16.0, 11.0]}, {"char_text": "o", "char_box": [33.0, 2.0, 43.0, 2.0, 36.0, 12.0, 25.0, 12.0]}, {"char_text": "m", "char_box": [46.0, 2.0, 61.0, 2.0, 53.0, 12.0, 39.0, 12.0]}, {"char_text": ":", "char_box": [61.0, 2.0, 69.0, 2.0, 63.0, 12.0, 55.0, 12.0]}], "text": "From:"}

+# KIE: Difference between CloseSet & OpenSet
+
+Being trained on WildReceipt, SDMG-R, or other KIE models, can identify the types of text boxes on a receipt picture.
+But what SDMG-R can do is far more beyond that. For example, it's able to identify key-value pairs on the picture. To demonstrate such ability and hopefully facilitate future research, we release a demonstrative version of WildReceiptOpenset annotated in OpenSet format, and provide a full training/testing pipeline for KIE models such as SDMG-R.
+Since it might be a *confusing* update, we'll elaborate on the key differences between the OpenSet and CloseSet format, taking WildReceipt as an example.
+
+## CloseSet
+
+WildReceipt ("CloseSet") divides text boxes into 26 categories. There are 12 key-value pairs of fine-grained key information categories, such as (`Prod_item_value`, `Prod_item_key`), (`Prod_price_value`, `Prod_price_key`) and (`Tax_value`, `Tax_key`), plus two more "do not care" categories: `Ignore` and `Others`.
+
+The objective of CloseSet SDMGR is to predict which category fits the text box best, but it will not predict the relations among text boxes. For instance, if there are four text boxes "Hamburger", "Hotdog", "$1" and "$2" on the receipt, the model may assign `Prod_item_value` to the first two boxes and `Prod_price_value` to the last two, but it can't tell if Hamburger sells for $1 or $2. However, this could be achieved in the open-set variant.
+
+
+
+
+
+
+:::{warning}
+
+A `*_key` and `*_value` pair do not necessarily have to both appear on the receipt. For example, we usually won't see `Prod_item_key` appearing on the receipt, while there can be multiple boxes annotated as `Pred_item_value`. In contrast, `Tax_key` and `Tax_value` are likely to appear together since they're usually structured as `Tax`: `11.02` on the receipt.
+
+:::
+
+## OpenSet
+
+In OpenSet, all text boxes, or nodes, have only 4 possible categories: `background`, `key`, `value`, and `others`. The connectivity between nodes are annotated as *edge labels*. If a pair of key-value nodes have the same edge label, they are connected by an valid edge.
+
+Multiple nodes can have the same edge label. However, only key and value nodes will be linked by edges. The nodes of same category will never be connected.
+
+When making OpenSet annotations, each node must have an edge label. It should be an unique one if it falls into non-`key` non-`value` categories.
+
+:::{note}
+You can merge `background` to `others` if telling background apart is not important, and we provide this choice in the conversion script for WildReceipt .
+:::
+
+### Converting WildReceipt from CloseSet to OpenSet
+
+We provide a [conversion script](../datasets/kie.md) that converts WildRecipt-like dataset to OpenSet format. This script links every `key`-`value` pairs following the rules above. Here's an example illustration: (For better understanding, all the node labels are presented as texts)
+

+
+A common request from our community is to extract the relations between food items and food prices. In this case, this conversion script ***is not you need***.
+Wildrecipt doesn't provide necessary information to recover this relation. For instance, there are four text boxes "Hamburger", "Hotdog", "$1" and "$2" on the receipt, and here's how they actually look like before and after the conversion:
+
+|box_content | closeset_node_label| closeset_edge_label | openset_node_label | openset_edge_label |
+| :----: | :---: | :----: | :---: | :---: |
+| Hamburger | Prod_item_value | - | Value | 0 |
+| Hotdog | Prod_item_value | - | Value | 0 |
+| $1 | Prod_price_value | - | Value | 1 |
+| $2 | Prod_price_value | - | Value | 1 |
+
+So there won't be any valid edges connecting them. Nevertheless, OpenSet format is far more general than CloseSet, so this task can be achieved by annotating the data from scratch.
+
+|box_content | openset_node_label | openset_edge_label |
+| :----: | :---: | :---: |
+| Hamburger | Value | 0 |
+| Hotdog | Value | 1 |
+| $1 | Value | 0 |
+| $2 | Value | 1 |

+## 重要提醒
+
+:::{note}
+**若用户需要在 CTW1500, ICDAR 2015/2017 或 Totaltext 数据集上训练模型**, 请注意这些数据集中有部分图片的 EXIF 信息里保存着方向信息。MMCV 采用的 OpenCV 后端会默认根据方向信息对图片进行旋转；而由于数据集的标注是在原图片上进行的，这种冲突会使得部分训练样本失效。因此，用户应该在配置 pipeline 时使用 `dict(type='LoadImageFromFile', color_type='color_ignore_orientation')` 以避免 MMCV 的这一行为。（配置文件可参考 [DBNet 的 pipeline 配置](https://github.com/open-mmlab/mmocr/blob/main/configs/_base_/det_pipelines/dbnet_pipeline.py)）
+:::
+
+
+## 准备步骤
+
+### ICDAR 2015
+- 第一步：从[下载地址](https://rrc.cvc.uab.es/?ch=4&com=downloads)下载 `ch4_training_images.zip`、`ch4_test_images.zip`、`ch4_training_localization_transcription_gt.zip`、`Challenge4_Test_Task1_GT.zip` 四个文件，分别对应训练集数据、测试集数据、训练集标注、测试集标注。
+- 第二步：运行以下命令，移动数据集到对应文件夹
+```bash
+mkdir icdar2015 && cd icdar2015
+mkdir imgs && mkdir annotations
+# 移动数据到目录：
+mv ch4_training_images imgs/training
+mv ch4_test_images imgs/test
+# 移动标注到目录：
+mv ch4_training_localization_transcription_gt annotations/training
+mv Challenge4_Test_Task1_GT annotations/test
+```
+- 第三步：下载 [instances_training.json](https://download.openmmlab.com/mmocr/data/icdar2015/instances_training.json) 和 [instances_test.json](https://download.openmmlab.com/mmocr/data/icdar2015/instances_test.json)，并放入 `icdar2015` 文件夹里。或者也可以用以下命令直接生成 `instances_training.json` 和 `instances_test.json`:
+```bash
+python tools/data/textdet/icdar_converter.py /path/to/icdar2015 -o /path/to/icdar2015 -d icdar2015 --split-list training test
+```
+
+### ICDAR 2017
+- 与上述步骤类似。
+
+### CTW1500
+- 第一步：执行以下命令，从 [下载地址](https://github.com/Yuliang-Liu/Curve-Text-Detector) 下载 `train_images.zip`，`test_images.zip`，`train_labels.zip`，`test_labels.zip` 四个文件并配置到对应目录：
+
+```bash
+mkdir ctw1500 && cd ctw1500
+mkdir imgs && mkdir annotations
+
+# 下载并配置标注
+cd annotations
+wget -O train_labels.zip https://universityofadelaide.box.com/shared/static/jikuazluzyj4lq6umzei7m2ppmt3afyw.zip
+wget -O test_labels.zip https://cloudstor.aarnet.edu.au/plus/s/uoeFl0pCN9BOCN5/download
+unzip train_labels.zip && mv ctw1500_train_labels training
+unzip test_labels.zip -d test
+cd ..
+# 下载并配置数据
+cd imgs
+wget -O train_images.zip https://universityofadelaide.box.com/shared/static/py5uwlfyyytbb2pxzq9czvu6fuqbjdh8.zip
+wget -O test_images.zip https://universityofadelaide.box.com/shared/static/t4w48ofnqkdw7jyc4t11nsukoeqk9c3d.zip
+unzip train_images.zip && mv train_images training
+unzip test_images.zip && mv test_images test
+```
+- 第二步：执行以下命令，生成 `instances_training.json` 和 `instances_test.json`。
+
+```bash
+python tools/data/textdet/ctw1500_converter.py /path/to/ctw1500 -o /path/to/ctw1500 --split-list training test
+```
+
+### SynthText
+
+- 下载 [data.mdb](https://download.openmmlab.com/mmocr/data/synthtext/instances_training.lmdb/data.mdb) 和 [lock.mdb](https://download.openmmlab.com/mmocr/data/synthtext/instances_training.lmdb/lock.mdb) 并放置到 `synthtext/instances_training.lmdb/` 中.
+
+### TextOCR
+ - 第一步：下载 [train_val_images.zip](https://dl.fbaipublicfiles.com/textvqa/images/train_val_images.zip)，[TextOCR_0.1_train.json](https://dl.fbaipublicfiles.com/textvqa/data/textocr/TextOCR_0.1_train.json) 和 [TextOCR_0.1_val.json](https://dl.fbaipublicfiles.com/textvqa/data/textocr/TextOCR_0.1_val.json) 到 `textocr` 文件夹里。
+ ```bash
+ mkdir textocr && cd textocr
+
+ # 下载 TextOCR 数据集
+ wget https://dl.fbaipublicfiles.com/textvqa/images/train_val_images.zip
+ wget https://dl.fbaipublicfiles.com/textvqa/data/textocr/TextOCR_0.1_train.json
+ wget https://dl.fbaipublicfiles.com/textvqa/data/textocr/TextOCR_0.1_val.json
+
+ # 把图片移到对应目录
+ unzip -q train_val_images.zip
+ mv train_images train
+ ```
+
+ - 第二步：生成 `instances_training.json` 和 `instances_val.json`:
+ ```bash
+ python tools/data/textdet/textocr_converter.py /path/to/textocr
+ ```
+
+### Totaltext
+ - 第一步：从 [github dataset](https://github.com/cs-chan/Total-Text-Dataset/tree/master/Dataset) 下载 `totaltext.zip`，从 [github Groundtruth](https://github.com/cs-chan/Total-Text-Dataset/tree/master/Groundtruth/Text) 下载 `groundtruth_text.zip` 。（建议下载 `.mat` 格式的标注文件，因为我们提供的标注格式转换脚本 `totaltext_converter.py` 仅支持 `.mat` 格式。）
+ ```bash
+ mkdir totaltext && cd totaltext
+ mkdir imgs && mkdir annotations
+
+ # 图像
+ # 在 ./totaltext 中执行
+ unzip totaltext.zip
+ mv Images/Train imgs/training
+ mv Images/Test imgs/test
+
+ # 标注文件
+ unzip groundtruth_text.zip
+ cd Groundtruth
+ mv Polygon/Train ../annotations/training
+ mv Polygon/Test ../annotations/test
+
+ ```
+ - 第二步：用以下命令生成 `instances_training.json` 和 `instances_test.json` ：
+ ```bash
+ python tools/data/textdet/totaltext_converter.py /path/to/totaltext -o /path/to/totaltext --split-list training test
+ ```

+## 评估 ONNX 和 TensorRT 模型（试验性的）
+
+我们在 `tools/deployment/deploy_test.py ` 中提供了评估 TensorRT 和 ONNX 模型的方法。
+
+### 前提条件
+在评估 ONNX 和 TensorRT 模型之前，首先需要安装 ONNX，ONNXRuntime 和 TensorRT。根据 [ONNXRuntime in mmcv](https://mmcv.readthedocs.io/en/latest/onnxruntime_op.html) 和 [TensorRT plugin in mmcv](https://github.com/open-mmlab/mmcv/blob/master/docs/tensorrt_plugin.md) 安装 ONNXRuntime 定制操作和 TensorRT 插件。
+
+### 使用
+
+```bash
+python tools/deploy_test.py \
+ ${CONFIG_FILE} \
+ ${MODEL_PATH} \
+ ${MODEL_TYPE} \
+ ${BACKEND} \
+ --eval ${METRICS} \
+ --device ${DEVICE}
+```
+
+### 参数说明
+
+| 参数 | 类型 | 描述 |
+| -------------- | ------------------------- | ------------------------------------------------------ |
+| `model_config` | str | 模型配置文件的路径。 |
+| `model_file` | str | TensorRT 或 ONNX 模型路径。 |
+| `model_type` | 'recog', 'det' | 部署检测还是识别模型。 |
+| `backend` | 'TensorRT', 'ONNXRuntime' | 测试后端。 |
+| `--eval` | 'acc', 'hmean-iou' | 评估指标。“acc”用于识别模型，“hmean-iou”用于检测模型。 |
+| `--device` | str | 评估使用的设备。默认为 `cuda:0`。 |

+- TensorRT 上采样（upsample）操作和 PyTorch 有一点不同。对于 DBNet 和 PANet，我们建议把上采样的最近邻 (nearest) 模式代替成双线性 (bilinear) 模式。 PANet 的替换处在[这里](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpem_ffm.py#L33) ，DBNet 的替换处在[这里](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpn_cat.py#L111)和[这里](https://github.com/open-mmlab/mmocr/blob/50a25e718a028c8b9d96f497e241767dbe9617d1/mmocr/models/textdet/necks/fpn_cat.py#L121)。如在上表中显示的，带有标记*的网络的上采样模式均被改变了。
+- 注意到，相比最近邻模式，使用更改后的上采样模式会降低性能。然而，默认网络的权重是通过最近邻模式训练的。为了保持在部署中的最佳性能，建议在训练和 TensorRT 部署中使用双线性模式。
+- 所有 ONNX 和 TensorRT 模型都使用数据集上的动态尺寸进行评估，图像根据原始配置文件进行预处理。
+- 这个工具仍然是试验性的。一些定制的操作模型没有被支持。并且我们目前仅支持一部分的文本检测和文本识别算法。

+# 开始
+
+在这个指南中，我们将介绍一些常用的命令，来帮助你熟悉 MMOCR。我们同时还提供了[notebook](https://github.com/open-mmlab/mmocr/blob/main/demo/MMOCR_Tutorial.ipynb) 版本的代码，可以让您快速上手 MMOCR。
+
+## 安装
+
+查看[安装指南](install.md)，了解完整步骤。
+
+## 数据集准备
+
+MMOCR 支持许多种类数据集，这些数据集根据其相应任务的类型进行分类。可以在以下部分找到它们的准备步骤：[检测数据集](datasets/det.md)、[识别数据集](datasets/recog.md)、[KIE 数据集](datasets/kie.md)和 [NER 数据集](datasets/ner.md)。
+
+## 使用预训练模型进行推理
+
+下面通过一个简单的命令来演示端到端的识别：
+
+```shell
+python mmocr/utils/ocr.py demo/demo_text_ocr.jpg --print-result --imshow
+```
+
+其检测结果将被打印出来，并弹出一个新窗口显示结果。更多示例和完整说明可以在[示例](demo.md)中找到。
+
+## 训练
+
+### 小数据集训练
+
+在`tests/data`目录下提供了一个用于训练演示的小数据集，在准备学术数据集之前，它可以演示一个初步的训练。
+
+例如：用 `seg` 方法和小数据集来训练文本识别任务，
+```shell
+python tools/train.py configs/textrecog/seg/seg_r31_1by16_fpnocr_toy_dataset.py --work-dir seg
+```
+
+用 `sar` 方法和小数据集训练文本识别,
+```shell
+python tools/train.py configs/textrecog/sar/sar_r31_parallel_decoder_toy_dataset.py --work-dir sar
+```
+
+### 使用学术数据集进行训练
+
+按照说明准备好所需的学术数据集后，最后要检查模型的配置是否将 MMOCR 指向正确的数据集路径。假设在 ICDAR2015 数据集上训练 DBNet,部分配置如 `configs/_base_/det_datasets/icdar2015.py` 所示:
+```python
+dataset_type = 'IcdarDataset'
+data_root = 'data/icdar2015'
+train = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_training.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+test = dict(
+ type=dataset_type,
+ ann_file=f'{data_root}/instances_test.json',
+ img_prefix=f'{data_root}/imgs',
+ pipeline=None)
+train_list = [train]
+test_list = [test]
+```
+这里需要检查数据集路径 `data/icdar2015` 是否正确. 然后可以启动训练命令：
+```shell
+python tools/train.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py --work-dir dbnet
+```
+
+想要了解完整的训练参数配置可以查看 [Training](training.md)了解。
+
+## 测试
+
+假设我们完成了 DBNet 模型训练，并将最新的模型保存在 `dbnet/latest.pth`。则可以使用以下命令，及`hmean-iou`指标来评估其在测试集上的性能：
+```shell
+python tools/test.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py dbnet/latest.pth --eval hmean-iou
+```
+
+还可以在线评估预训练模型，命令如下：
+```shell
+python tools/test.py configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py https://download.openmmlab.com/mmocr/textdet/dbnet/dbnet_r18_fpnc_sbn_1200e_icdar2015_20210329-ba3ab597.pth --eval hmean-iou
+```
+
+有关测试的更多说明，请参阅 [测试](testing.md).

+
+## 详细安装步骤
+
+a. 创建一个 Conda 虚拟环境并激活（open-mmlab 为自定义环境名）。
+
+```shell
+conda create -n open-mmlab python=3.7 -y
+conda activate open-mmlab
+```
+
+b. 按照 PyTorch 官网教程安装 PyTorch 和 torchvision ([参见官方链接](https://pytorch.org/)), 例如,
+
+```shell
+conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch
+```
+
+:::{note}
+请确定 CUDA 编译版本和运行版本一致。你可以在 [PyTorch](https://pytorch.org/) 官网检查预编译 PyTorch 所支持的 CUDA 版本。
+:::
+
+c. 安装 [mmcv](https://github.com/open-mmlab/mmcv)，推荐以下方式进行安装。
+
+```shell
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/{cu_version}/{torch_version}/index.html
+```
+
+请将上述 url 中 ``{cu_version}`` 和 ``{torch_version}``替换成你环境中对应的 CUDA 版本和 PyTorch 版本。例如，如果想要安装最新版基于 CUDA 11 和 PyTorch 1.7.0 的最新版 `mmcv-full`，请输入以下命令:
+
+```shell
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7.0/index.html
+```
+
+:::{note}
+PyTorch 在 1.x.0 和 1.x.1 之间通常是兼容的，故 mmcv-full 只提供 1.x.0 的编译包。如果你的 PyTorch 版本是 1.x.1，你可以放心地安装在 1.x.0 版本编译的 mmcv-full。
+
+```bash
+# 我们可以忽略 PyTorch 的小版本号
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu110/torch1.7/index.html
+```
+
+:::
+
+:::{note}
+如果安装时进行了编译过程，请再次确认安装的 `mmcv-full` 版本与环境中 CUDA 和 PyTorch 的版本匹配。
+
+如有需要，可以在[此处](https://github.com/open-mmlab/mmcv#installation)检查 mmcv 与 CUDA 和 PyTorch 的版本对应关系。
+:::
+
+:::{warning}
+如果你已经安装过 `mmcv`，你需要先运行 `pip uninstall mmcv` 删除 `mmcv`，再安装 `mmcv-full`。 如果环境中同时安装了 `mmcv` 和 `mmcv-full`, 将会出现报错 `ModuleNotFoundError`。
+:::
+
+d. 安装 [mmdet](https://github.com/open-mmlab/mmdetection), 我们推荐使用pip安装最新版 `mmdet`。
+在 [此处](https://pypi.org/project/mmdet/) 可以查看 `mmdet` 版本信息.
+
+```shell
+pip install mmdet
+```
+
+或者，你也可以按照 [安装指南](https://github.com/open-mmlab/mmdetection/blob/master/docs/get_started.md) 中的方法安装 `mmdet`。
+
+e. 克隆 MMOCR 项目到本地.
+
+```shell
+git clone https://github.com/open-mmlab/mmocr.git
+cd mmocr
+```
+
+f. 安装依赖软件环境并安装 MMOCR。
+
+```shell
+pip install -r requirements.txt
+pip install -v -e . # or "python setup.py develop"
+export PYTHONPATH=$(pwd):$PYTHONPATH
+```
+
+## 完整安装命令
+
+以下是 conda 方式安装 mmocr 的完整安装命令。
+
+```shell
+conda create -n open-mmlab python=3.7 -y
+conda activate open-mmlab
+
+# 安装最新的 PyTorch 预编译包
+conda install pytorch==1.6.0 torchvision==0.7.0 cudatoolkit=10.1 -c pytorch
+
+# 安装最新的 mmcv-full
+pip install mmcv-full -f https://download.openmmlab.com/mmcv/dist/cu101/torch1.6.0/index.html
+
+# 安装 mmdet
+pip install mmdet
+
+# 安装 mmocr
+git clone https://github.com/open-mmlab/mmocr.git
+cd mmocr
+
+pip install -r requirements.txt
+pip install -v -e . # 或 "python setup.py develop"
+export PYTHONPATH=$(pwd):$PYTHONPATH
+```
+
+## 可选方式: Docker镜像
+
+我们提供了一个 [Dockerfile](https://github.com/open-mmlab/mmocr/blob/master/docker/Dockerfile) 文件以建立 docker 镜像 。
+
+```shell
+# build an image with PyTorch 1.6, CUDA 10.1
+docker build -t mmocr docker/
+```
+
+使用以下命令运行。
+
+```shell
+docker run --gpus all --shm-size=8g -it -v {实际数据目录}:/mmocr/data mmocr
+```
+
+## 数据集准备
+
+我们推荐建立一个 symlink 路径映射，连接数据集路径到 `mmocr/data`。 详细数据集准备方法请阅读**数据集**章节。
+如果你需要的文件夹路径不同，你可能需要在 configs 文件中修改对应的文件路径信息。
+
+ `mmocr` 文件夹路径结构如下：
+
+```
+├── configs/
+├── demo/
+├── docker/
+├── docs/
+├── LICENSE
+├── mmocr/
+├── README.md
+├── requirements/

+# 服务器部署
+
+`MMOCR` 预先提供了一些脚本来加速模型部署服务流程。下面快速介绍一些在服务器端通过调用 API 来进行模型推理的必要步骤。
+
+## 安装 TorchServe
+
+你可以根据[官网](https://github.com/pytorch/serve#install-torchserve-and-torch-model-archiver)步骤来安装 `TorchServe` 和
+`torch-model-archiver` 两个模块。
+
+## 将 MMOCR 模型转换为 TorchServe 模型格式
+
+我们提供了一个便捷的工具可以将任何以 `.pth` 为后缀的模型转换为以 `.mar` 结尾的模型来满足 TorchServe 使用要求。
+
+```shell
+python tools/deployment/mmocr2torchserve.py ${CONFIG_FILE} ${CHECKPOINT_FILE} \
+--output-folder ${MODEL_STORE} \
+--model-name ${MODEL_NAME}
+```
+
+:::{note}
+${MODEL_STORE} 必须是文件夹的绝对路径。
+:::
+
+例如：
+
+```shell
+python tools/deployment/mmocr2torchserve.py \
+ configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py \
+ checkpoints/dbnet_r18_fpnc_1200e_icdar2015.pth \
+ --output-folder ./checkpoints \
+ --model-name dbnet
+```
+
+## 启动服务
+
+### 本地启动
+
+准备好模型后，使用一行命令即可启动服务：
+
+```bash
+# 加载所有位于 ./checkpoints 中的模型文件
+torchserve --start --model-store ./checkpoints --models all
+# 或者你仅仅使用一个模型服务，比如 dbnet
+torchserve --start --model-store ./checkpoints --models dbnet=dbnet.mar
+```
+
+然后，你可以通过 TorchServe 的 REST API 访问 Inference、 Management、 Metrics 等服务。你可以在[TorchServe REST API](https://github.com/pytorch/serve/blob/master/docs/rest_api.md) 中找到它们的用法。
+
+
+| 服务 | 地址 |
+| ------------------- | ----------------------- |
+| Inference | `http://127.0.0.1:8080` |
+| Management | `http://127.0.0.1:8081` |
+| Metrics | `http://127.0.0.1:8082` |
+
+:::{note}
+TorchServe 默认会将服务绑定到端口 `8080`、 `8081` 、 `8082` 上。你可以通过修改 `config.properties` 来更改端口及存储位置等内容，并通过可选项 `--ts-config config.preperties` 来运行 TorchServe 服务。
+
+```bash
+inference_address=http://0.0.0.0:8080
+management_address=http://0.0.0.0:8081
+metrics_address=http://0.0.0.0:8082
+number_of_netty_threads=32
+job_queue_size=1000
+model_store=/home/model-server/model-store
+```
+
+:::
+
+
+### 通过 Docker 启动
+
+通过 Docker 提供模型服务不失为一种更好的方法。我们提供了一个 Dockerfile，可以让你摆脱那些繁琐且容易出错的环境设置步骤。
+
+#### 构建 `mmocr-serve` Docker 镜像
+
+```shell
+docker build -t mmocr-serve:latest docker/serve/
+```
+
+#### 通过 Docker 运行 `mmocr-serve`
+
+为了在 GPU 环境下运行 Docker， 首先需要安装 [nvidia-docker](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html)；或者你也可以只使用 CPU 环境而不必加 `--gpus` 参数。
+
+下面的命令将使用 gpu 运行，将 Inference、 Management、 Metric 的端口分别绑定到8080、8081、8082上，将容器的IP绑定到127.0.0.1上，并将检查点文件夹 `./checkpoints` 从主机挂载到容器的 `/home/model-server/model-store` 文件夹下。更多相关信息，请查看官方文档中 [docker中运行 TorchServe 服务](https://github.com/pytorch/serve/blob/master/docker/README.md#running-torchserve-in-a-production-docker-environment)。
+
+```shell
+docker run --rm \
+--cpus 8 \
+--gpus device=0 \
+-p8080:8080 -p8081:8081 -p8082:8082 \
+--mount type=bind,source=`realpath ./checkpoints`,target=/home/model-server/model-store \
+mmocr-serve:latest
+```
+
+:::{note}
+`realpath ./checkpoints` 指向的是 "./checkpoints" 的绝对路径，你也可以将其替换为你的 torchserve 模型所在的绝对路径。
+:::
+
+运行docker后，你可以通过 TorchServe 的 REST API 访问 Inference、 Management、 Metrics 等服务。具体你可以在[TorchServe REST API](https://github.com/pytorch/serve/blob/master/docs/rest_api.md) 中找到它们的用法。
+
+| 服务 | 地址 |
+| ------------------- | ----------------------- |
+| Inference | http://127.0.0.1:8080 |
+| Management | http://127.0.0.1:8081 |
+| Metrics | http://127.0.0.1:8082 |
+
+
+
+## 4. 测试单张图片推理
+
+推理 API 允许用户上传一张图到模型服务中，并返回相应的预测结果。
+
+```shell
+curl http://127.0.0.1:8080/predictions/${MODEL_NAME} -T demo/demo_text_det.jpg
+```
+
+例如，
+
+```shell
+curl http://127.0.0.1:8080/predictions/dbnet -T demo/demo_text_det.jpg
+```
+
+对于检测模型，你会获取到名为 boundary_result 的 json 对象。内部的每个数组包含以浮点数格式的，按顺时针排序的 x， y 边界顶点坐标。数组的最后一位为置信度分数。
+```json
+{
+ "boundary_result": [
+ [
+ 221.18990004062653,
+ 226.875,
+ 221.18990004062653,
+ 212.625,
+ 244.05868631601334,
+ 212.625,
+ 244.05868631601334,
+ 226.875,
+ 0.80883354575186
+ ]
+ ]
+}
+```
+
+对于识别模型，返回的结果如下：
+
+```json
+{
+ "text": "sier",
+ "score": 0.5247521847486496
+}
+```
+
+同时可以使用 `test_torchserve.py` 来可视化对比 TorchServe 和 PyTorch 结果。
+
+```shell
+python tools/deployment/test_torchserve.py ${IMAGE_FILE} ${CONFIG_FILE} ${CHECKPOINT_FILE} ${MODEL_NAME}
+[--inference-addr ${INFERENCE_ADDR}] [--device ${DEVICE}]
+```
+
+例如：
+
+```shell
+python tools/deployment/test_torchserve.py \
+ demo/demo_text_det.jpg \
+ configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py \
+ checkpoints/dbnet_r18_fpnc_1200e_icdar2015.pth \
+ dbnet
+```

+# 测试
+
+此文档介绍在数据集上测试预训练模型的方法。
+
+## 使用单 GPU 进行测试
+
+您可以使用 `tools/test.py` 执行单 CPU/GPU 推理。例如，要在 IC15 上评估 DBNet: ( 可以从 [Model Zoo]( ../../README_zh-CN.md#模型库) 下载预训练模型 )：
+
+```shell
+./tools/dist_test.sh configs/textdet/dbnet/dbnet_r18_fpnc_1200e_icdar2015.py dbnet_r18_fpnc_sbn_1200e_icdar2015_20210329-ba3ab597.pth --eval hmean-iou
+```
+
+下面是脚本的完整用法:
+
+```shell
+python tools/test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} [ARGS]
+```
+
+:::{note}
+默认情况下，MMOCR 更偏向于使用 GPU 而非 CPU。如果您想在 CPU 上测试模型，请清空 `CUDA_VISIBLE_DEVICES` 或者将其设置为 -1 以使 GPU(s) 对程序不可见。需要注意的是，运行 CPU 测试需要 **MMCV >= 1.4.4**。
+
+```bash
+CUDA_VISIBLE_DEVICES= python tools/test.py ${CONFIG_FILE} ${CHECKPOINT_FILE} [ARGS]
+```
+
+:::
+
+
+
+| 参数 | 类型 | 描述 |
+| ------------------ | --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `--out` | str | 以 pickle 格式输出结果文件。 |
+| `--fuse-conv-bn` | bool | 所选 det 模型的自定义配置的路径。 |
+| `--format-only` | bool | 格式化输出结果文件而不执行评估。 当您想将结果格式化为特定格式并将它们提交到测试服务器时，它很有用。 |
+| `--gpu-id` | int | 要使用的 GPU ID。仅适用于非分布式训练。 |
+| `--eval` | 'hmean-ic13', 'hmean-iou', 'acc' | 不同的任务使用不同的评估指标。对于文本检测任务，指标是 'hmean-ic13' 或者 'hmean-iou'。对于文本识别任务，指标是 'acc'。 |
+| `--show` | bool | 是否显示结果。 |
+| `--show-dir` | str | 将用于保存输出图像的目录。 |
+| `--show-score-thr` | float | 分数阈值 (默认值: 0.3)。 |
+| `--gpu-collect` | bool | 是否使用 gpu 收集结果。 |
+| `--tmpdir` | str | 用于从多个 workers 收集结果的 tmp 目录，在未指定 gpu-collect 时可用。 |
+| `--cfg-options` | str | 覆盖使用的配置中的一些设置，xxx=yyy 格式的键值对将被合并到配置文件中。如果要覆盖的值是一个列表，它应当是 key ="[a,b]" 或者 key=a,b 的形式。该参数还允许嵌套列表/元组值，例如 key="[(a,b),(c,d)]"。请注意，引号是必需的，并且不允许使用空格。 |
+| `--eval-options` | str | 用于评估的自定义选项，xxx=yyy 格式的键值对将是 dataset.evaluate() 函数的 kwargs。 |
+| `--launcher` | 'none', 'pytorch', 'slurm', 'mpi' | 工作启动器的选项。 |
+
+## 使用多 GPU 进行测试
+
+MMOCR 使用 `MMDistributedDataParallel` 实现 **分布式**测试。
+
+您可以使用以下命令测试具有多个 GPU 的数据集。
+
+
+```shell
+[PORT={PORT}] ./tools/dist_test.sh ${CONFIG_FILE} ${CHECKPOINT_FILE} ${GPU_NUM} [PY_ARGS]
+```
+
+| 参数 | 类型 | 描述 |
+| --------- | ---- | -------------------------------------------------------------------------------- |
+| `PORT` | int | rank 为 0 的机器将使用的主端口。默认为 29500。 |
+| `PY_ARGS` | str | 由 `tools/test.py` 解析的参数。 |
+
+例如，
+
+```shell
+./tools/dist_test.sh configs/example_config.py work_dirs/example_exp/example_model_20200202.pth 1 --eval hmean-iou
+```
+
+## 使用 Slurm 进行测试
+
+如果您在使用 [Slurm](https://slurm.schedmd.com/) 管理的集群上运行 MMOCR， 则可以使用脚本 `tools/slurm_test.sh`。
+
+```shell
+[GPUS=${GPUS}] [GPUS_PER_NODE=${GPUS_PER_NODE}] [SRUN_ARGS=${SRUN_ARGS}] ./tools/slurm_test.sh ${PARTITION} ${JOB_NAME} ${CONFIG_FILE} ${CHECKPOINT_FILE} [PY_ARGS]
+```
+
+| 参数 | 类型 | 描述 |
+| --------------- | ---- | ----------------------------------------------------------------------------------------------------------- |
+| `GPUS` | int | 此任务要使用的 GPU 数量。默认为 8。 |
+| `GPUS_PER_NODE` | int | 每个节点要分配的 GPU 数量。默认为 8。 |
+| `SRUN_ARGS` | str | srun 解析的参数。可以在[此处](https://slurm.schedmd.com/srun.html)找到可用选项。|
+| `PY_ARGS` | str | 由 `tools/test.py` 解析的参数。 |
+
+下面是一个在 "dev" 分区上运行任务的示例。该任务名为 "test_job"，其调用了 8 个 GPU 对示例模型进行评估 。
+
+```shell
+GPUS=8 ./tools/slurm_test.sh dev test_job configs/example_config.py work_dirs/example_exp/example_model_20200202.pth --eval hmean-iou
+```
+
+## 批量测试
+
+默认情况下，MMOCR 仅对逐张图像进行测试。为了令推理更快，您可以在配置中更改
+`data.val_dataloader.samples_per_gpu` 和 `data.test_dataloader.samples_per_gpu` 字段。
+
+例如，
+```
+data = dict(
+ ...
+ val_dataloader=dict(samples_per_gpu=16),
+ test_dataloader=dict(samples_per_gpu=16),
+ ...
+)
+```
+
+将使用 16 张图像作为一个批大小测试模型。
+
+:::{warning}
+批量测试时数据预处理管道的行为会有所变化，因而可能导致模型的性能下降。
