When ever python breaks, notebook blows up etc etc I often find that the source of my problem is the fact I had installed <STRONG>Deep learning libraries for ArcGIS Pro</STRONG>. I have to use the Windows Add/Remove to remove the deep learning packages and often follow that up with a repair on ArcPro. That often fixes the issue.</P><P>Something to explore...</P> Fri, 24 Nov 2023 17:16:00 GMT https://community.esri.com/t5/python-questions/kernel-error-failed-to-start-the-kernel-arcgis-pro/m-p/1353192#M69282 DuncanHornby 2023-11-24T17:16:00Z
