Installation and API key setup was done as described in the readme, but when running

from chemcrow.agents import ChemCrow

I am getting the error

ModuleNotFoundError: No module named 'langchain_core.schema'

langchain is installed and version confirmed to be 0.0.275.

Thanks in advance!

Hi there! Thank you for your feedback.

The issue has been solved, can you try installing again with pip install chemcrow -U

The problem was the langchain_core library which wasn't pinned and was simply pointing to the newest (0.0.6) that has no langchain_core.schema module, while the first version (0.0.1) does.
