# YOLOS (small-sized) model
|
18 |
+
|
19 |
+
The original YOLOS model was fine-tuned on COCO 2017 object detection (118k annotated images). It was introduced in the paper [You Only Look at One Sequence: Rethinking Transformer in Vision through Object Detection](https://arxiv.org/abs/2106.00666) by Fang et al. and first released in [this repository](https://github.com/hustvl/YOLOS).
|
20 |
+
|
21 |
+
This model was further fine-tuned on the [face mask dataset]("https://www.kaggle.com/datasets/andrewmvd/face-mask-detection") from Kaggle. The dataset consists of 853 images of people with annotations categorised as "with mask","without mask" and "mask not worn correctly". The model was trained for 200 epochs on a single GPU usins Google Colab
|
22 |
+
|
23 |
+
## Model description
|
24 |
+
|
25 |
+
YOLOS is a Vision Transformer (ViT) trained using the DETR loss. Despite its simplicity, a base-sized YOLOS model is able to achieve 42 AP on COCO validation 2017 (similar to DETR and more complex frameworks such as Faster R-CNN).
|
26 |
+
|
27 |
+
## Intended uses & limitations
|
28 |
+
|
29 |
+
You can use the raw model for object detection. See the [model hub](https://huggingface.co/models?search=hustvl/yolos) to look for all available YOLOS models.

### How to use
|
32 |
+
|
33 |
+
Here is how to use this model:
|
34 |
+
|
35 |
+
```python
|
36 |
+
from transformers import YolosFeatureExtractor, YolosForObjectDetection
|
37 |
+
from PIL import Image
|
38 |
+
import requests
|
39 |
+
url = 'https://drive.google.com/uc?id=1VwYLbGak5c-2P5qdvfWVOeg7DTDYPbro'
|
40 |
+
image = Image.open(requests.get(url, stream=True).raw)
|
41 |
+
feature_extractor = YolosFeatureExtractor.from_pretrained('nickmuchi/yolos-small-finetuned-masks')
|
42 |
+
model = YolosForObjectDetection.from_pretrained('nickmuchi/yolos-small-finetuned-masks')
|
43 |
+
inputs = feature_extractor(images=image, return_tensors="pt")
|
44 |
+
outputs = model(**inputs)
|
45 |
+
# model predicts bounding boxes and corresponding face mask detection classes
|
46 |
+
logits = outputs.logits
|
47 |
+
bboxes = outputs.pred_boxes
|
48 |
+
```
|
49 |
+
|
50 |
+
Currently, both the feature extractor and model support PyTorch.
|
51 |
+
|
52 |
+
## Training data
|
53 |
+
|
54 |
+
The YOLOS model was pre-trained on [ImageNet-1k](https://huggingface.co/datasets/imagenet2012) and fine-tuned on [COCO 2017 object detection](https://cocodataset.org/#download), a dataset consisting of 118k/5k annotated images for training/validation respectively.
|
55 |
+
|
56 |
+
### Training
