博客内容涉及到Python多进程编程中出现的错误，具体表现为在尝试启动新进程前，当前进程尚未完成初始化。错误提示强调可能未使用fork方式启动子进程，并提醒在主模块中正确使用`if __name__ == '__main__':`和`freeze_support()`。同时，代码中存在局部变量`Machine`在使用前未被正确赋值。解决方法包括定义全局变量`Machine`和检查多进程启动逻辑。

        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:

                freeze_support()

        The "freeze_support()" line can be omitted if the program
        is not going to be frozen to produce an executable.    raise RuntimeError('''
