It's likely that an unstable network connection or a firewall have caused an incomplete download. Check if these URLs are accessible manually:

If it was a temporary connection issue, retrying it will probably work.

In my case, the problem is happening repeatedly. I feel like the issue is deeper, because I've never had problems with an unstable connection completely aborting downloads like this.

In my case, when I encountered this error for the first time, I reran the code below again and there was no error.

import torch
import clip
from PIL import Image

device = "cuda" if torch.cuda.is_available() else "cpu"
model, preprocess = clip.load("ViT-B/32", device=device)

image = preprocess(Image.open("CLIP.png")).unsqueeze(0).to(device)
text = clip.tokenize(["a diagram", "a dog", "a cat"]).to(device)

@jongwook's suggestion worked for my whisper issue. I had to create the $HOME/.cache/clip directory and then download the ViT.*pt files into it. Thanks @jongwook !
