Summary: Resubmit of https://github.com/pytorch/pytorch/pull/25980. Our old serialization was in tar (like `resnet18-5c106cde.pth` was in this format) so let's only support automatically unzip if checkpoints are zipfiles. We can still manage to get it work with tarfile, but let's delay it when there's an ask. Pull Request resolved: https://github.com/pytorch/pytorch/pull/26723 Differential Revision: D17551795 Pulled By: ailzhang fbshipit-source-id: 00b4e7621f1e753ca9aa07b1fe356278c6693a1e
