Hello,
I would like to enable certain nbextensions in my Jupyter Notebooks, for example the Autopep8 extension.
I tried to follow the documentation on this page: Install and enable notebook extensions - Help
I executed the following command jupyter nbextension enable Autopep8, but it says the module could not be found.
So I assumed the extension is not available, so I followed the section on how to enable extension that is not provided by SWAN:
pip install --user Autopep8
export JUPYTER_DATA_DIR=$CERNBOX_HOME/.local/share/jupyter
jupyter nbextension install --py --symlink --user Autopep8
jupyter nbextension enable Autopep8 --user --py
Unfortunately, an exception is thrown upon the execution of the third command:
Traceback (most recent call last):

What might be the problem here? Thanks for your help.
