調用stop_conversation時發生TypErrror（）

Question

我試圖擴展谷歌助理，以便能夠使用我自己的本地命令，它正在工作，但語音仍然響應「我無法幫助你」或類似的東西。當我嘗試使用stop_conversation()方法我得到一個錯誤：

TypeError: unbound method stop_conversation() must be called with Assistant instance as first argument (got nothing instead)

我該如何解決這個問題？

if __name__ == '__main__': 

    main() 

這是我爲我的谷歌助理項目模擬的代碼，我想這就是你要找的。 stop_conversation應該和助手函數一起調用，否則會溢出錯誤。
