This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:
if __name__ == '__main__':
freeze_support()
...
The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.

BrokenPipeError: [Errno 32] Broken pipe
I notice that you are using Windows platform.The error is related to the multithreading of Dataloader on Windows. For more details, see this issue. You could try setting num_workers=0. But this will slow down the speed of data loading. I recommend to run the code on Ubuntu platform.
Thanks for you reply. My problem is solved. I will accept your recommend to run the code on Ubuntu platform.
