Phoenix in Python: Debug RAG Failures with Traces and Evals

About this lesson

Debug RAG pipelines with Phoenix traces and Python to pinpoint whether the retriever or the generator failed. Learn a reproducible workflow to trace retrieval runs, replay traced runs, inspect retriever outputs and generated text, and attach eval spans to find failing links fast. Demo uses Phoenix (OpenTelemetry bridge), Phoenix Python client and pandas with span instrumentation and a keyword-recall evaluation.
