Jupyter無法運行websocket錯誤

Juputer無法連接

系websocket連接出問題，瀏覽器控制檯報錯 ws 連接異常

WebSocket connection to 'ws://localhost:8888/api/kernels/f8809bf9-988f-4666-b183-e01bed63fa76/channels?session_id=e49c21f065e64e7a89847a0859d689dd' failed: Error during WebSocket handshake: Unexpected response code: 200

解決方案

卸載龍捲風6並重新安裝龍捲風5。

pip uninstall tornado
pip install tornado==5.1.1
