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 (Welcome to star! 🔥🔥) ## Use with the official API We provide a simple code snippet to show how to use the API of Chinese-CLIP to compute the image & text embeddings and similarities. ```python from PIL import Image import requests from transformers import ChineseCLIPProcessor, ChineseCLIPModel model = ChineseCLIPModel.from_pretrained("OFA-Sys/chinese-clip-vit-huge-patch14") processor = ChineseCLIPProcessor.from_pretrained("OFA-Sys/chinese-clip-vit-huge-patch14") url = "https://clip-cn-beijing.oss-cn-beijing.aliyuncs.com/pokemon.jpeg" image = Image.open(requests.get(url, stream=True).raw) # Squirtle, Bulbasaur, Charmander, Pikachu in English texts = ["杰尼龟", "妙蛙种子", "小火龙", "皮卡丘"] # compute image feature inputs = processor(images=image, return_tensors="pt") image_features = model.get_image_features(**inputs) image_features = image_features / image_features.norm(p=2, dim=-1, keepdim=True) # normalize # compute text features inputs = processor(text=texts, padding=True, return_tensors="pt") text_features = model.get_text_features(**inputs) text_features = text_features / text_features.norm(p=2, dim=-1, keepdim=True) # normalize # compute image-text similarity scores inputs = processor(text=texts, images=image, return_tensors="pt", padding=True) outputs = model(**inputs) logits_per_image = outputs.logits_per_image # this is the image-text similarity score probs = logits_per_image.softmax(dim=1) # probs: [[1.1419e-02, 1.0478e-02, 5.2018e-04, 9.7758e-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.
