"""Example of how to add MemGPT into an AutoGen groupchat and chat with docs.

See https://memgpt.readthedocs.io/en/latest/autogen/#loading-documents

Based on the official AutoGen example here: https://github.com/microsoft/autogen/blob/main/notebook/agentchat_groupchat.ipynb

Begin by doing:
  pip install "pyautogen[teachable]"
  pip install pymemgpt
  or
  pip install -e . (inside the MemGPT home directory)
