[Python] Trying to run googlesamples-assistant-pushtotalk results in syntax error after hours...

So I've been building a smart mirror that (hopefully) uses google-cloud-console to integrate google assistant to a raspberry pi for voice command. I am not a programmer. Long story short, google-assistant-pushtotalk required a python version <=3.9. Installed python 3.8.20 via pyenv. In the end I'm left with a syntax error when trying to run. Here are the steps I took.

On first execution, the following error was given.

mirror@raspberrypi:~/.pyenv/versions/3.8.20/bin $ ~/.pyenv/versions/3.8.20/bin/googlesamples-assistant-pushtotalk
Traceback (most recent call last):

_message.Message._CheckCalledFromGeneratedFile()
TypeError: Descriptors cannot be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).


at this point i ran the following pip uninstall protobuf and pip install protobuf==3.20.0

Now when trying to run 'googlesamples-assistant-pushtotalk' I get the following error.

mirror@raspberrypi:~/.pyenv/versions/3.8.20/bin $ /home/mirror/.pyenv/versions/3.8.20/bin/googlesamples-assistant-pushtotalk

SyntaxError: invalid syntax```


I don't have any ideas on how to proceed. I've spent a good amount of time trying to figure this out on my own and I just do not have the aptitude. If someone could help in any way, I can't put into words how grateful I would be. Thank you for your time.
