问题：你好朋友，我正在尝试制作一个可以处理不和谐的聊天机器人，并且可以通过我构建的人工智能模型给出答案，但是我收到了 RuntimeWarning: E​​nable tracemalloc to get the object allocation traceback 和 RuntimeError: This event loop is already running 我该如何解决这些问题？

Answer 1

您的错误是因为您不断重新启动discord.Client。在每个程序中，应该只有一个discord.Client 的实例。如果你想让它吐出最后一个响应，你应该把客户端移出循环。设置机器人对全局变量的响应，并在发送命令时让机器人吐出全局变量
