# Chinese-CLIP-ViT-Large-Patch14 |
|
|
|
## Introduction |
|
This is the huge-version of the Chinese CLIP, with ViT-H/14 as the image encoder and RoBERTa-wwm-large as the text encoder. Chinese CLIP is a simple implementation of CLIP on a large-scale dataset of around 200 million Chinese image-text pairs. For more details, please refer to our technical report https://arxiv.org/abs/2211.01335 and our official github repo https://github.com/OFA-Sys/Chinese-CLIP |
|
|
|
## Use with the official API |
|
We provide a simple code snippet to show how to use the API for Chinese-CLIP. For starters, please install cn_clip: |
|
```bash |
|
# to install the latest stable release |
|
pip install cn_clip |
|
|
|
# or install from source code |
|
cd Chinese-CLIP |
|
pip install -e . |
|
``` |
|
After installation, use Chinese CLIP as shown below: |
|
```python |
|
import torch |
|
from PIL import Image |
|
|
|
import cn_clip.clip as clip |
|
from cn_clip.clip import load_from_name, available_models |
|
print("Available models:", available_models()) |
|
# Available models: ['ViT-B-16', 'ViT-L-14', 'ViT-L-14-336', 'ViT-H-14', 'RN50'] |
|
|
|
device = "cuda" if torch.cuda.is_available() else "cpu" |
|
model, preprocess = load_from_name("ViT-H-14", device=device, download_root='./') |
|
model.eval() |
|
image = preprocess(Image.open("examples/pokemon.jpeg")).unsqueeze(0).to(device) |
|
text = clip.tokenize(["杰尼龟", "妙蛙种子", "小火龙", "皮卡丘"]).to(device) |
|
|
|
with torch.no_grad(): |
|
image_features = model.encode_image(image) |
|
text_features = model.encode_text(text) |
|
# Normalize the features. Please use the normalized features for downstream tasks. |
|
image_features /= image_features.norm(dim=-1, keepdim=True) |
|
text_features /= text_features.norm(dim=-1, keepdim=True) |
|
|
|
logits_per_image, logits_per_text = model.get_similarity(image, text) |
|
probs = logits_per_image.softmax(dim=-1).cpu().numpy() |
|
|
|
print("Label probs:", probs) # [[1.268734e-03 5.436878e-02 6.795761e-04 9.436829e-01]] |
|
``` |
|
|
|
However, if you are not satisfied with only using the API, feel free to check our github repo https://github.com/OFA-Sys/Chinese-CLIP for more details about training and inference. |
