研究方向
The issue describes duplicated logger messages in ArviZ notebooks. Likely cause: duplicate handlers added to the root logger. Investigate the logger configuration in arviz/ init .py or arviz/utils.py to find where handlers are added. Ensure only one handler is attached to avoid duplication. The fix may involve using a singleton pattern for the logger or removing extra handlers. The screenshots show examples in cookbook and refitting notebooks, so reproduction may require running those notebooks with the current codebase.
