    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.

Hi @nickyoungforu

Sorry for the late response. I was wondering if you have tried running the code with Python3.6.

This is what we used for the code. It might be that the latest version of python is causing some environment error :)
