/home/dmitry/.pyenv/versions/3.11.6/lib/python3.11/site-packages/langgraph/checkpoint/__init__.py:2: LangChainDeprecationWarning: As of langchain-core 0.3.0, LangChain uses pydantic v2 internally. The langchain_core.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_core.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

For example, replace imports like: `from langchain_core.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 from langgraph.checkpoint.memory import MemorySaver Traceback (most recent call last): File

This was FREAKING venv !
For some reason it stucked at langgraph 0.0.36
Guys, pay attention to it! Just delete venv folder and create a new one (a new venv)
Don't pay attention what is described in poetry.lock file - always do pip show langgraph
