Question about error for context encoder

Created by: IvanChen777

Hi, I have a question about the error for context encoder, when I follow the instruction to train the model, I met such issue, that is: 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.

Does someone knows how to solve this problem? Thank you in advance!
