excuse me，your code bring me a big help about my research，but,when i run the train.py,it appears the following errors,do you konw how to fix it? thank you!
RuntimeError:
An attempt has been made to start a new process before the
current process has finished its bootstrapping phase.

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.

ForkingPickler(file, protocol).dump(obj)
BrokenPipeError: [Errno 32] Broken pipe

Please use the following code:

if __name__ == "__main__":
  torch.multiprocessing.freeze_support()
  main()
