Hi Ben, I closed the issue because I noticed someone else already posted about it. Sorry for the inconvenience! No, I haven't found a solution yet! Very nice book! I'm one of the people who likes to learn through books, I can't grasp information from video tutorials :) and I found your book to be very helpful!

Hi @raniat123
I think we've already talked about this on the discord server. The link looks very relevant, however, that doesn't seem to be the problem, as I can run the code without any issue. Let me take the discussion here, since this will be available for more people:

This could be a problem with the pydantic version that you have installed. Could you please check that it's version 1.10.13?

When I've just rerun the code, I've come across one issue as well, but unrelated - I had an issue with the LLM output. But after changing the llm like this:

llm = ChatOpenAI(model_name="gpt-3.5-turbo")

I got it to work. I've changed this in the information extraction module.
