Bug#1085071: Thanks for your information

[EiPiFun <me@eipi.fun>]

Hello, Andrey!

The problem is that its GitHub release does not contains all files.
You can check the file:
https://github.com/googleapis/google-cloud-python/archive/refs/tags/google-ai-generativelanguage-v0.6.10.tar.gz

An easy and good solution is that they add docs in its pypi release.
I suggest them to do so:
https://github.com/googleapis/google-cloud-python/issues/13168

Or, add setup.py or pyproject.toml in their GitHub release.

Best regards,
EiPi Fun/Dong Xu
