IPython 5.1.0

Widget Javascript not detected.  It may not be installed properly. Did you enable the widgetsnbextension? If not, then run "jupyter nbextension enable --py --sys-prefix widgetsnbextension"

I run

jupyter nbextension enable --py --sys-prefix widgetsnbextension

and rerun ipython console. But still

Pardon,

Kernel restarting was not enough. I had to stop/start ipython process.
