Hi, I'm having issues loading RN50x64 model recently released in Jan 2022.

Running:
model, preprocess = clip.load("RN50x64", device=device)

returns:
RuntimeError: Model RN50x64 not found; available models = ['RN50', 'RN101', 'RN50x4', 'RN50x16', 'ViT-B/32', 'ViT-B/16']

Is there a way to load the larger model for evaluation?

Thanks!

Maybe you should add 'RN50x64' to _MODELS in https://github.com/openai/CLIP/blob/main/clip/clip.py

Did you make it work? I am having the same problem with the Vit-L/14 version. @adrielkuek

This should work after reinstalling the package from the latest commit. As an alternative, downloading the checkpoint from the URLs in clip.py and loading its path with clip.load would also work.
