我是raspberry和python的新手，并且我已经使用Raspbian在Raspberry Pi 4 B上使用本教程https://pimylifeup.com/raspberry-pi-google-assistant/安装了Google助手。
这很好：
googlesamples-assistant-pushtotalk
进行测试，出现以下错误：
(env) pi@raspberrypi:~ $ google-assistant-demo --project-id XXX
Traceback (most recent call last):
File "/home/pi/env/bin/google-assistant-demo", line 8, in <module>
sys.exit(main())
File "/home/pi/env/lib/python3.7/site-packages/google/assistant/library/__main__.py", line 119, in main
raise Exception('Missing --device-model-id option')
Exception: Missing --device-model-id option
也运行“ googlesamples-assistant-hotword”只会给我带来内存访问错误。
我正在尝试使其在启动时免提工作，因此我使用sudo systemctl status assistant.service来给我：
● assistant.service - Google Assistant

我认为这些错误可能是相关的。
非常感谢您。
