Failed to install google-assistant-sdk[samples] to raspberry pi Zero W

I am attempting to install the Google Assistant to a raspberry pi Zero W.

During the last step it to failed to complete install google-assistant-sdk[samples].

I am running python 3.9.2 on the pi Zero. Python 3 is also loaded.

I have loaded the following to my Pi Zero as part of the setup for running the assistant, per the Google Assistant SDK setup instructions.

sudo apt-get update
sudo apt-get install python3-dev python3-venv
python3 -m venv env
env/bin/python -m pip install --upgrade pip setuptools wheel

Then I activated the virtual env

source env/bin/activate

In the virtual env I loaded

sudo apt-get install portaudio19-dev libffi-dev libssl-dev

The final step requires loading the Google assistant SDK, this is where it goes wrong.

python -m pip install --upgrade google-assistant-sdk[samples]

Initially the setup seems to be going well, then while preparing the metadata after downloading grpcio-1.47.0.tar.gz the subprocess exits with an error.

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I have rerun this several times, still in the virtual env, specifying either python3 or python3.9

python3 -m pip install --upgrade google-assistant-sdk[samples]

python3.9 -m pip install --upgrade google-assistant-sdk[samples]

I get the same error everytime.

At this point I am not sure what I can do differently.

I am looking for some guidance on next steps.
