Run this program in linux would fix it, pytorch implements different solutions in function DataLoaderIter ,so it can't work well in windows.

Thanks a lot!

Hi, in case that you are still interested to run it in Windows 10 again.
Here is a tested solution ( I have tested it on 3 PC with AMD/intel CPU and NVIDIA GPUS, so just give it a shot...).

To fix the issue, change your num_worker in config.py to 0 so that it will use the main thread (only one process) ->(multithreading/process related error is a common issue in Window).
