Users can install the current version of ipywidgets with pip or conda.
pip install ipywidgets
jupyter nbextension enable --py widgetsnbextensionWhen using virtualenv and working in
an activated virtual environment, the --sys-prefix option may be required
to enable the extension and keep the environment isolated (i.e.
jupyter nbextension enable --py widgetsnbextension --sys-prefix).
conda install -c conda-forge ipywidgetsInstalling ipywidgets with conda will also enable the extension for you.
