did all agents move to llama_index.core.

llama_index.agent for agent integrations that are experimental or 3rd party
https://llamahub.ai/?tab=agent

core has the react and function calling agent

is there a specific package we need to install for IntrospectiveAgentWorker?
i installed llama-index-agent-introspective and it keeps saying ModuleNotFoundError: No module named 'llama_index.agent'

this is what i get when i type poetry show

@shawtyisaten maybe try a fresh venv? It works in google colab

Or if you are in a notebook, try restarting it after you install things

thanks
