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

Question

this code was working fine before, and now it raise this error when calling GooglePalm with langchain. The error:

----> 8 llm = GooglePalm(). NotImplementedError: Need to determine which default deprecation schedule to use. within ?? minor releases.

My code:

import google.generativeai as palm
from langchain.embeddings import GooglePalmEmbeddings
from langchain.llms import GooglePalm
palm.configure(api_key=GOOGLE_API_KEY)
llm = GooglePalm()

Answer 1

I solved it by upgradown langchain version:

!pip uninstall langchain
!pip install langchain==0.0.339

Answer 2

Please use a lower version of Langchain

langchain==0.0.284
langchain==0.0.339

and used code like

api_key = ''
llm = GooglePalm(google_api_key=api_key, temperature=0.2)
