When I run main.py , the program has a bug What can i do and what is the problem？

Well, provide some suggestions from new bing:

Hello, this is Bing. It seems that you are running into a RuntimeError when using PyTorch on Windows. This error may be caused by a problem with multiprocessing and shared memory12. One possible solution is to set num_workers=0 in your DataLoader function2. Another possible solution is to use Linux instead of Windows3. Have you tried any of these solutions?

Thanks for your reply! The early num_workers=10 and I just set it to 8 ,I don't know if this will run successfully to the end
