import robustness. dataset "No module named 'torchvision.models.utils'"

[yifan6210]

Hi, package developers,

I encountered an issue with the import robustness. dataset and I think the potential problem occurs in the vgg.py file under imagenet models.

potential changes from

from torchvision.models.utils import load_state_dict_from_url

to

from torch.hub import load_state_dict_from_url

This was updated in github but not in PyPi

To fix this, the owner of the repository just needs to push the updates to PyPi.
