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.

Would you like to help me, please?

I saw a link above, it was said:
They are not supported on Windows. Something like doing multiprocessing on CUDA tensors cannot succeed, there are two alternatives for this.

Don’t use multiprocessing. Set the num_worker of DataLoader to zero.
Share CPU tensors instead. Make sure your custom DataSet returns CPU tensors.

I am using windows 10.
