Google Assistant Raspberry Pi Problem | hotword not working

Question

i am new to raspberry and python and i've installed the Google Assistant using this tutorial https://pimylifeup.com/raspberry-pi-google-assistant/ on my Raspberry Pi 4 B using Raspbian.

This works fine:

googlesamples-assistant-pushtotalk 

Testing it, i get the following errors:

(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

Also running " googlesamples-assistant-hotword " just gives me a memory access error.

I am trying to get it to work handsfree on boot so i used sudo systemctl status assistant.service wich gives me:

● assistant.service - Google Assistant
   Loaded: loaded (/lib/systemd/system/assistant.service; enabled; vendor preset

I think the errors are probably related.

Thank you very much in advance.

您需要按照官方文档创建设备模型 ID，然后在运行项目时传递该参数。
