Got it, thanks Adam K.. Do you have a snippet of LangChain code that reproduces the issue, or is it any LangChain code whatsoever?

Adam K. I'm not able to reproduce the issue. I left a link to a modified version of the notebook you sent and the requirements that worked for me on the GitHub issue. Can you sync your requirements to the ones I provided and see if that allows you to run the notebook?
