Hi everyone, I'm trying to follow the example about Guidance for Sub-Question Query Engine (https://gpt-index.readthedocs.io/en/latest/examples/output_parsing/guidance_sub_question.html). Which version of guidance is compatible with llama-index?. I use the colab as base, an install guidance, but it's not working. I'm currently getting the following error: "ImportError: cannot import name 'Program' from 'guidance' (/usr/local/lib/python3.10/dist-packages/guidance/init.py)".

hi everyone!, I'm using llamaindex (great library an community by the way congrats!) to build a RAG application for question answering legal text (chilean laws in particular). Laws have a specific structure like: title, paragraph and articles. I would like to add that structure as metadata to the chunk nodes, does anyone faced a similar problem who can give a little guidance?. Thanks in advance
