Getting freeze_support() error

Hello I'm getting the following error when I run the command 'python ./model/Twitter/BiGCN_Weibo.py 100' I've tested it on Colab, PyCharm, and by using WindowsShell

    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.
