Curt K. Are you looking at integrating LangChain with the Arize Cloud (Production Monitoring & Observability use cases) or OSS Phoenix (Early stage development use case)?
The notebook you are using is old and is about to be replaced as we release LLM LangChain spans and traces officially in Arize cloud.
The exact spans and traces look in Phoenix is about to be released into Arize in about 1-2 weeks, we have it in Beta with a number of customers testing.
Let me recommend the following. Check out the Phoenix with LangChain notebook here:
https://colab.research.google.com/github/Arize-ai/phoenix/blob/main/tutorials/tracing/langchain_tracing_tutorial.ipynb
https://docs.arize.com/phoenix/concepts/llm-traces
We will drop the updated LangChain notebook for Arize cloud shortly.
