Hi @mraguth , if you run the following in your notebook, what does it say?

!ls

This looks similar to a common python gotcha where if you have a file called langgraph.py or a directory called langgraph in your current working directory, the imports won't resolve correctly.

Thank you....It got resolved by installing below... I appreciate your quick response.

# %%capture --no-stderr
# %pip install -U langchain langchain_openai langsmith pandas langchain_experimental matplotlib langgraph langchain_core

Got it - went back through notebooks to uncomment installs + fix up some missing ones so hopefully becomes less common
