How to use just gemini-pro model

[dwk601]

I imported the .env file with gemini api key, and un # to load gemini model to agents but I'm still getting an error, could you upload or show how to just use gemini-pro model.

Exception has occurred: ValidationError

can you show the code of using gemini-pro model related? In my case, I can run it successfully, here is my code.

from langchain_google_genai import ChatGoogleGenerativeAI

llm_gemini = ChatGoogleGenerativeAI(
    model='gemini-pro', verbose=True, temperature=0.1, google_api_key=os.getenv('GEMINI_API_KEY')
)

...

explorer = Agent(
  ...
  llm=llm_gemini
)
