File size of resnet18 model (pretrained vs. from scratch)

When you save your weights, you also save the optimizer state (unless you say with_opt=False ). That’s where the difference comes from.

This is actually also the right answer for my question in this thread. If I save my model with

learner.save('foo.model', with_opt=False)

the file size is reduced to 47 MB
