If I try to load resnet50 after downloading the pretrained weights, with the code
start = time.time()
resnet = torchvision.models.resnet50(pretrained=True)
print('resnet50 loaded in {} seconds'.format(time.time()-start))

I get
resnet50 loaded in 0.41980624198913574 seconds

and similar times for vgg, densenet, etc. However, for inception_v3, I get
inception_v3 loaded in 184.83905911445618 seconds

Is there a reason inception takes so much longer to load?
