Do you know how I can fix this problem in PyTorch 1.9?
File "main.py", line 138, in main
    checkpoint = torch.load(args.resume)
  File "/scratch3/venv/fashcomp/lib/python3.8/site-packages/torch/serialization.py", line 608, in load
    return _legacy_load(opened_file, map_location, pickle_module, **pickle_load_args)
  File "/scratch3/venv/fashcomp/lib/python3.8/site-packages/torch/serialization.py", line 787, in _legacy_load
    result = unpickler.load()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbe in position 2: invalid start byte
