树莓派谷歌助理

Question

我需要关于我哪里出了问题的帮助。我跟踪了https://pimylifeup.com/raspberry-pi-google-assistant/。程序要求我输入一个请求，但它不会通过扬声器输出答案。当我和麦克风交谈时，我已经附上了(发送请求)。

Answer 1

我不认为这是一个答案。当在覆盆子上安装助手SDK时，刚刚经历了同样的问题。不幸的是，Python没有做太多事情，但我认为关键是

File "/home/pi/env/lib/python3.9/site-backages/googlesamples/assistant/grpc/audio_helpers.py", line 57, in normalize_audio_buffer
buf = arr.tostring()
AttributeError: 'array.array' object has no attribute 'tostring'

可能是什么类型的演员问题？或者一个不受欢迎的函数。明天，我将回到一个更老的Python，然后再试一次。
