redis-ai-resources/python-recipes/RAG /01_redisvl.ipynb- section : Improve personalization by including chat session history

[amscosta]

Hi , Trying to reproduce the above section but getting the pink error cell message below. Should I restart the kernel and play those cells in sequence ?

Hey @amscosta I re-ran all the cells in the colab environment and was unable to recreate your issue.

From your error message it seems that the llmcache doesn't exist. This can be for redis connection errors or potentially other unknown reasons.

Check by running this cell:

If you're running locally potentially check that your redis instance is running and available on localhost:6379.

Thanks for the output. I am running locally. Can you test locally? Maybe also indicate the exact sequence of cells to be run ?
