BrokenPipeError: [Errno 32] Broken pipe

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.

你解决了吗？好兄弟

[YaleFeng]

我在train.py的最后一行，train_n_valid前面加了if name == main:，好像解决了

num_works改成0试试
