I followed the instructions from here to test the new Gemini provider. However, it does not show up on the model list. Any advice?

@giswqs Thank you very much for your contribution! This will be really useful once it's released. There remains only a minor concern that needs to be addressed.

It would also be helpful if you could include a screenshot (or preferably a video) of Gemini working in Jupyter AI after making these changes. That would help verify that this PR behaves as expected. 👍

@dlqqq I have made the changes as suggested, but Gemini still does not show up on the provider list. Anything else I should change?

The following code snippet works without the jupyter-ai magic command.

from langchain_google_genai import GoogleGenerativeAI

llm = GoogleGenerativeAI(model="gemini-pro")
result = llm.invoke("Write a ballad about LangChain")
print(result)

I figured it out. I just need to reinstall the packages using the following command line. It now works properly

jlpm dev-uninstall && jlpm dev-install

Here is a demo showing Gemini in action @dlqqq @@simonff

There are more Gemini models available. Let me work on adding them.

I have added a few more gemini models to the list.

https://ai.google.dev/api/python/google/generativeai
https://ai.google.dev/api/python/google/generativeai/list_models

# pip install google-generativeai
import pprint
import google.generativeai as genai

for model in genai.list_models():
    pprint.pprint(model.name)

@giswqs Awesome work, thank you! I've rebased this branch on the latest main and fixed the merge conflicts. Will merge this, pending passing CI. 🚀

I had missed your question earlier in my review, my apologies. You are correct in recognizing that you need to run jlpm dev-install if you are updating the entry points in pyproject.toml. I've opened a new issue to add this info to the contributor documentation, so other contributors won't experience the same pain point. 👍

Congrats on your first merged pull request in this project! 🎉
