在python中调用start（）时发生运行时错误

Question

def maxpackages():

    while max_packages:

        print("maxpackages")
        # Loop to send amount from config file of msg to server
        for x in range(parser.getint('MaximumPackages', 'MaximumPackages')):
            msg = 'maxpackages'
            mp = multiprocessing.Process(target=sock.sendto, args=(msg.encode(), server_address))
            mp.start()
        resp, server = sock.recvfrom(4096)
        server_resp = resp.decode()
        print(server_resp)
        sock.close()
        break

错误消息： RuntimeError： 尝试在启动新进程之前启动新进程。 当前进程已完成其引导阶段。

    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.
