Couldn't build proto file into descriptor pool

[shirsakm]

Description of the bug:

I encounter the error "TypeError: Couldn't build proto file into descriptor pool: duplicate symbol "'google.ai.generativelanguage.v1beta.firstlineno'", when trying to import this module.

Actual vs expected behavior:

The module should import correctly and work as in the Quickstart guide.

Any other information you'd like to share?

I am using PyCharm and the module installed is google-generativeai.

Hi @shirsakm

I tried to reproduce the code in the PyCharm environment, and the basic Quickstart guide is functioning correctly. Would you like to try reinstalling or upgrading the google-generativeai package?

Thanks

I was able to fix the issue by downgrading from Python 3.13 to 3.12.

Same here, happened on py3.13, not happened in py3.12

I was able to fix the issue by downgrading from Python 3.13 to 3.12.

Downgrading to 3.12.6 worked for me as well.

Running into the same issue on python 3.13, downgrading to 3.12 seems to fix the problem for now.

And I just got 3.13 installed... Oh well, back to 3.12.7 it is.
