Using a low version of pytorch to load a model saved with a high version of pytorch (1.6+) will report an error

xxx.pt is a zip archive(did you mean to use torch.jit.load()?

The 1.6 release of PyTorch switched torch.save to use a new zipfile-based file format. torch.load still retains the ability to load files in the old format. If for any reason you want torch.save to use the old format, pass the kwarg _use_new_zipfile_serialization=False.
