Issue with Version Conflicts While Upgrading to Gemini 2.5 (Google Generative AI & LangChain) I am switching to Gemini 2.5 Experimental from Gemini 1.5 and trying to upgrade the versions of google-ai-generativelanguage and google-generativeai to support Gemini 2.5.

I am using a requirements.txt file to manage dependencies, but due to version conflicts, I am unable to install the dependencies properly.

I tried using:

google-ai-generativelanguage==0.6.15

google-generativeai==0.8.4

However, these versions are not compatible with my current langchain version.

Issue When I install my requirements.txt, I get dependency conflicts between langchain, google-ai-generativelanguage, and google-generativeai.

• python-3.x

• 3 why not relax the absolute versions and let pip try to figure out a working combo for you? – JonSG Commented Mar 31 at 17:20

Starting with Gemini 1.5 and Gemini 2.0, you should use Google Gen AI SDK, which provides a unified interface to Gemini 2.0 and 1.5 (and should be for Gemini 2.5 when GA) through both the Gemini Developer API and the Gemini API on Vertex AI. So, you just need: google-genai (version 1.7.0 as of now). You no longer need google-ai-generativelanguage.

I tested the latest google-genai with lanchain modules, seems installing fine.

langchain==0.2.6
langchain-community==0.2.6
langchain-core==0.2.10
langchain-google-genai==1.0.7
langchain-text-splitters==0.2.2
langsmith==0.1.82
google-genai==1.7.0

Please review the Google Gen AI SDK documentation for detail.
