ZH-CLIP: A Chinese CLIP Model

Models

You can download ZH-CLIP model from 🤗 thu-ml/zh-clip-vit-roberta-large-patch14. The model structure is shown below:

Getting Started

Dependency

• python >= 3.9
• pip install -r requirements.txt

Inference

You can clone code from https://github.com/thu-ml/zh-clip

from PIL import Image
import requests
from models.zhclip import ZhCLIPProcessor, ZhCLIPModel  # Code in https://github.com/thu-ml/zh-clip

version = 'thu-ml/zh-clip-vit-roberta-large-patch14'
model = ZhCLIPModel.from_pretrained(version)
processor = ZhCLIPProcessor.from_pretrained(version)

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = processor(text=["一只猫", "一只狗"], images=image, return_tensors="pt", padding=True)

outputs = model(**inputs)
image_features = outputs.image_features
text_features = outputs.text_features
text_probs = (image_features @ text_features.T).softmax(dim=-1)

Other Chinese CLIP Models

In addition, to compare the effectiveness of different methods, the inference methods of other Chinese CLIP models have been integrated. For the convenience of use, the inference code has also been made public, and please contact us if there is any infringement. The code only implements models at the same level as clip-vit-large-patch14, but it may be adapted for the use of more different versions of models in the future.
