以"openai/clip-vit-large-patch14"为例，原代码为：
self.tokenizer = CLIPTokenizer.from_pretrained(“openai/clip-vit-large-patch14”)
self.transformer = CLIPTextModel.from_pretrained(“openai/clip-vit-large-patch14”)
但我连不到外网没办法直接下载，所以去
https://huggingface.co/openai/clip-vit-large-patch14/tree/main
这个网页把所有文件下载下来，传到.cache/huggingface/transformers下，然后把代码改
# 校园网连不上huggingface
# self.tokenizer = CLIPTokenizer.from_pretrained(version)
# self.transformer = CLIPTextModel.from_pretrained(version)
local_path="/home/rongl/.cache/huggingface/transformers/{}".format(version.split('/')[-1])
# '/home/xxx/.cache/huggingface/transformers/clip-vit-large-patch14'
self.tokenizer = CLIPTokenizer.from_pretrained(local_path)
self.transformer = CLIPTextModel.from_pretrained(local_path)
