%pip show langchain – 1.1.o version.

Hi!
Based on your screenshot, you have langchain 1.1.0 installed, but the import fails.

Please try the following:

  1. Restart Your Kernel

After %pip install, the kernel can still have the old module cached. Go to Kernel → Restart (or Runtime → Restart Runtime in Colab).

  1. If that doesn’t work, do a clean reinstall:
%pip uninstall langchain langchain-core langgraph -y
%pip install langchain langchain-core langgraph

Then restart the kernel and run:

from langchain.agents import create_agent

If nothing helps, please gather version info for troubleshooting, run:

!pip list | grep -E "langchain|langgraph"

And provide the output of this command.
