remove import torchvision when testing torch.hub (#21132)
Summary:
This should pass once https://github.com/pytorch/vision/pull/971 is merged.
To remove torchvision as baseline, we just compare to sum of all param.sum() in pretrained resnet18 model, which means we need to manually update the number only when that pretrained weights are changed, which is generally rare.
