Mikyo and Dat: Just tried the llama index notebook suggested above and it's giving me errors. Is there another notebook related to retrieval that I should be trying? I tried the langchain inference notebooks again and they're still not working as well. At this point neither of the inference notebooks are working, but both of the tracing notebooks ARE working. But it's inference and cluster analysis that I'm really interested in
