Langchain error - NotImplementedError: Need to determine which default deprecation schedule to use. within ?? minor releases

I ran the bellow code. However, currently, it shows an error massage.

from langchain.llms import GooglePalm

api_key = 'my_API'


llm = GooglePalm(google_api_key=api_key,
                 temperature=0.1)

This is the error I got.

NotImplementedError                       Traceback (most recent call last)

    297                 f"{removal}"

NotImplementedError: Need to determine which default deprecation schedule to use. within ?? minor releases

Can someone please help me to solve this?

I need to create the large language model variable.

I also had a similar error, I'm using langchain==0.1.4 in which its google_palm file suggests deprecation of GooglePalm and it is replaced with langchain_google_genai.GoogleGenerativeAI

Make use of GoogleGenerativeAI instead; for its installation follow these steps:

1. pip install --upgrade --quiet langchain-google-genai
2. pip install -q -U google-generativeai

Then use this code:

from langchain_google_genai import GoogleGenerativeAI

llm = GoogleGenerativeAI(model="models/text-bison-001", google_api_key=SECRET_KEY, temperature=0.1)

Use Google Palm API key.
