Hi @Eric_Hou, nice what about loading the model from a newer version of pytorch (1.8.1) to and older version of pytorch (1.3.0) what would you need to add? I receive the error:
RuntimeError: test.pth is a zip archive (did you mean to use torch.jit.load()?)

Then when adding torch.jit.load, I receive the error message:
RuntimeError: version_number <= kMaxSupportedFileFormatVersion INTERNAL ASSERT FAILED at ../caffe2/serialize/inline_container.cc.......

Regards,
Abu
