@1hexf1 this problem is mainly caused by the python version. please refe to this issue. Please let me know if you could solve it. Thanks.

I have succeeded in solving the problem. InceptionV3 model loading problem.
It needs to download the model and replace it manually.
Also, I upgraded Pytorch to use Pytorch1.7.
