Lesson:
The notebook from “Multimodal RAG with Multimodal Langchain” works in the course container environment, but when I downloaded the necessary files and tried the notebook I had to

  1. make minor changes in the “prompt_processing” function
  2. When is comes to the mm_ragchain - after constructing the first one without the visual aspect, that itself when I invoke the query, I get the error that says: “ValueError: Could not make prediction. validation: top_k must be 1 or greater”
    I tried to pass **options with top_k: 10, when I do that I get the error that says unexpected parameter top_k encountered type of an error.
