用Pytorch训练保存模型，在human_play中加载模型报错

[bxdxstu]

Traceback (most recent call last):
File "E:/project/AlphaZero_Gomoku/human_play.py", line 68, in run
policy_param = pickle.load(open(model_file, 'rb'))
_pickle.UnpicklingError: A load persistent id instruction was encountered,
but no persistent_load function was specified.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
