Anaconda Fehler beim Starten von Python 3 Jupiter Notebook

Question

Ich erhalte einen Fehler, wenn ich versuche, ein Python 3 Notebook mit Jupyter nach der Installation von Anaconda3.5 zu öffnen. Es gibt kein Problem mit Python 2 Notebooks. Hier ist der Fehler

Answer 1

Wenn Sie python3 mit einem Conda Umgebung installiert, greifen Sie es wie folgt aus:

$ source activate <env name> 
$ jupyter notebook 

Sie an die Wurzel wie folgt wieder her:

$ source deactivate 

Wenn Sie Wenn Sie eine neue Instanz von Anaconda installiert haben, sollten Sie sie möglicherweise deinstallieren und neu installieren:

$ conda create -n py35 python=3.5 anaconda 

Answer 2

python -m IPython kernelspec install-self

hat den Trick
