[Python-modules-team] Bug#848252: jupyter-notebook: ipywidgets warning on startup

[Paride Legovini]

Package: jupyter-notebook
Version: 4.2.3-3
Severity: wishlist

Dear Maintainer,

When starting jupyter-notebook this warning is shown:

/usr/lib/python3/dist-packages/ipywidgets/__init__.py:67: RuntimeWarning: To
use the widgets with your installed Jupyter Notebook version, please install
ipywidgets 4.x or earlier.

This seems to be just a cosmetic issue, as the widgets work.
Installing python3-widgetsnbextension "solves" the issuem, but this package
should not be necessary, as its description says.

Thank you,

Paride
