# ConvNeXt V2 (large-sized model)
|
18 |
+
|
19 |
+
ConvNeXt V2 model pretrained using the FCMAE framework and fine-tuned on the ImageNet-22K dataset at resolution 384x384. It was introduced in the paper [ConvNeXt V2: Co-designing and Scaling ConvNets with Masked Autoencoders](https://arxiv.org/abs/2301.00808) by Woo et al. and first released in [this repository](https://github.com/facebookresearch/ConvNeXt-V2).
|
20 |
+
|
21 |
+
Disclaimer: The team releasing ConvNeXT V2 did not write a model card for this model so this model card has been written by the Hugging Face team.
|
22 |

|
23 |
+
## Model description
|
24 |
+
|
25 |
+
ConvNeXt V2 is a pure convolutional model (ConvNet) that introduces a fully convolutional masked autoencoder framework (FCMAE) and a new Global Response Normalization (GRN) layer to ConvNeXt. ConvNeXt V2 significantly improves the performance of pure ConvNets on various recognition benchmarks.

## Intended uses & limitations
|
30 |
+
|
31 |
+
You can use the raw model for image classification. See the [model hub](https://huggingface.co/models?search=convnextv2) to look for
|
32 |
+
fine-tuned versions on a task that interests you.
|

+
### How to use
|
35 |
+
|
36 |
+
Here is how to use this model to classify an image of the COCO 2017 dataset into one of the 1,000 ImageNet classes:
|
37 |
+
|
38 |
+
```python
|
39 |
+
from transformers import AutoImageProcessor, ConvNextV2ForImageClassification
|
40 |
+
import torch
|
41 |
+
from datasets import load_dataset
|
42 |
+
|
43 |
+
dataset = load_dataset("huggingface/cats-image")
|
44 |
+
image = dataset["test"]["image"][0]
|
45 |
+
|
46 |
+
preprocessor = AutoImageProcessor.from_pretrained("facebook/convnextv2-large-22k-384")
|
47 |
+
model = ConvNextV2ForImageClassification.from_pretrained("facebook/convnextv2-large-22k-384")
|
48 |
+
|
49 |
+
inputs = preprocessor(image, return_tensors="pt")
|
50 |
+
|
51 |
+
with torch.no_grad():
|
52 |
+
logits = model(**inputs).logits
|
53 |
+
|
54 |
+
# model predicts one of the 1000 ImageNet classes
|
55 |
+
predicted_label = logits.argmax(-1).item()
|
56 |
+
print(model.config.id2label[predicted_label]),
|
57 |
+
```
|
58 |
+
|
59 |
+
