What Slicer version are you using? On what operating system?

Try disable anti-virus programs if u have any. Control environmental path and check python path. Maybe your jupyter libraries were not installed on your path same as comm targets of Slicer. If u had not added slicer/bin file path to environments please do and try.  
Keep us informed.  
Good Luck

I’m encountering the same problem. This happens when run the “01\_Data\_loading\_and\_display.ipynb” - " Dynamic views". Adding slicer/bin file path to environments doesn’t solve the problem. I’m using windows and slicer 5.2.2
