Setting up Google AI Assistant SDK on Raspberry Pi 4

Question

I have followed the guidelines from https://developers.google.com/assistant/sdk/guides/service/python on how to set up Google AI Assistant SDK's and am trying to get it working on my Raspberry Pi 4. I have followed all steps accurately as far as I can see. However, when I am told to run the following sample code (with the project id and model id replaced by my project info):

googlesamples-assistant-pushtotalk --project-id --device-model-id

I encounter the following error:

/home/pi/env/lib/python3.9/site-packages/cffi/cparser.py:163: UserWarning: Global variable 'stderr' in cdef(): for consistency with C it should have a storage class specifier (usually 'extern')
warnings.warn("Global variable '%s' in cdef(): for consistency " /home/theaustingelatt/env/lib/python3.9/site-packages/cffi/cparser.py:163: UserWarning: Global variable '__stderrp' in cdef(): for consistency with C it should have a storage class specifier (usually 'extern')
warnings.warn("Global variable '%s' in cdef(): for consistency " Error: no such option: --project-id

I used the --help option and did not see --project-id listed as a viable option. However, this is confusing because I watched multiple tutorials all done in the same fashion work perfectly fine.

I also tried to run: googlesamples-assistant-pushtotalk --demo. However, the same error: no such option: --demo was populated.

I double and triple checked the documentation for the API setup and Actions Console setup and those appear to be in order.

Any help is appreciated!
