The langchain.pydantic_v1 module was a compatibility shim for pydantic v1, and should no longer be used. Please update the code to import from Pydantic directly. For example, replace imports like: `from langchain.pydantic_v1 import BaseModel` with: `from pydantic import BaseModel` or the v1 compatibility namespace if you are working in a code base that has not been fully upgraded to pydantic 2 yet. from pydantic.v1 import BaseModel )removal alternativemessageN)langchain_core._apirpydantic.v1.mainR/var/www/html/shao/venv/lib/python3.13/site-packages/langchain/pydantic_v1/main.pyr s!/ ) 0 r
