UnicodeDecodeError when loading the pre-trained model

Thank you for your great work!

When I tried to load the model you provided here, I encountered the following error:

Traceback (most recent call last):

    main()

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 1: invalid continuation byte

This problem occurred probably because I tried to decode in a different way from way of encoding. I would appreciate it if you could show me how this problem has happened, and how to solve it.

Thank you for your consideration!

I use default.py and never changed. _C.TRAIN.CHECKPOINT_TYPE = “pytorch”

Once I switch pytorch to caffe2, I succeeded in loading the pre-trained model. Thank you so much!!

Thank you for replying.

I use Python 3.7.3, which may cause this problem. I am going to use 3.6 and let you know what happens.
