Notebook extnesions that you install through e.g. pip install are not enabled by default.
As an example, suppose that we have installed the widgetsnbextension using
pip install widgetsnbextension --prefix=~/JHL_installations/Python |
Note that such extensions may also have been installed as dependencies of other pip packages, in which case you also may want to enable them.
To enable this notebook extension for all of your students (and youself), add the following to the ~/JHL_hooks/script hook:
jupyter nbextension enable --py widgetsnbextension --user |
