Ran into a few walls with LangGraph Integration Example

Local Version

Installation

Was difficult to figure out that I needed to run uv pip install -U openpipe-art[backend,langgraph]==0.4.9 discovered the extras from https://pypi.org/project/openpipe-art/ did not see stated in docks. Saw in Collab Notebook as well.

Unknown attributes

Cannot access attribute "register_model" for class "LocalBackend"
  Attribute "register_model" is unknown

Had to switch this from backend.register_model -> backend.register

"train" is not a known attribute of module "art"

Did not find a working method in my search for this. Saw that model had a method called _train_model but read was not implemented yet.

Decorator for wrap_rollout not working

Argument missing for parameter "fn"

I thought I had a workaround by passing run_agent before it created the trajectory but appears to not like the LangGraph message schema. My assumption is the decorator manages that.

Oof, this is actually on me! I generated the docs automatically based on the notebook, but it looks like CC hallucinated a couple methods. Will fix real quick!

@ryaneggz really sorry for the confusion! If you follow the updated docs, agent initialization and training should work properly now. Thanks for flagging!

@arcticfly no worries at all, ty for your help! Excited to dive back in tonight!
