Pourquoi je suis face à cela?

Answer 1

Je faisais la même question - si vous avez encore ce problème, le déclassement ipykernel à la version 4.3.0 semblait fonctionner pour moi comme une solution temporaire:

pip uninstall ipykernel 

pip install ipykernel=4.3.0 

Answer 2

Assurez-vous pour mettre à niveau ipykernel vers la dernière version (vous avez besoin d'au moins 4.5.0, qui a été publié le 2 septembre 2016). This pull request fixed that issue:

pip install --upgrade ipykernel 

Il y avait an issue as well in GitHub reporting the problem, qui a été fermé après la demande de tirage a été fusionné et 4.5.0 a été libéré.
