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 GooglePalmapi_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)<ipython-input-2-a3e32679669c> in <cell line: 7>()      5       6 # Create llm variable here----> 7 llm = GooglePalm(google_api_key=api_key,      8                  temperature=0.1)2 frames/usr/local/lib/python3.10/dist-packages/langchain_core/_api/deprecation.py in warn_deprecated(since, message, name, alternative, pending, obj_type, addendum, removal)    293         if not removal:    294             removal = f"in {removal}" if removal else "within ?? minor releases"--> 295             raise NotImplementedError(    296                 f"Need to determine which default deprecation schedule to use. "    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.
