Does this mean I can t use llama index s

Llama-Index uses some LLM classes from langchain

To me, this error says you need to import/use the ChatOpenAI class for the LLM you are using

Thanks. It doesn't make sense though that I get the error only when using streamlit 😅 I also imported it and nothing changed. I have to "use" it but I don't know how to use it in this context

What does the code in streamlit look like?

are you setting up a service context?

Ah...I fixed it. Thanks Logan! 🙂
