I tried to install jupyter_contrib_nbextensions : http://jupyter-contrib-nbextensions.readthedocs.io/en/latest/install.html
Everything worked fine but when I open a notebook nothing changes. I can't see the new tool bar that I'm supposed to see.
When I reinstall the Extension, the process is the same (I don't have a message tellign me that the files already exists). I don't have an error. So I can't figure out why it doesn't work.
Thanks a lot.
Project description. The jupyter_nbextensions_configurator jupyter server extension provides graphical user interfaces for configuring which nbextensions are enabled (load automatically for every notebook), and display their readme files.
Enable autocompletion (Hinterland)By checking the 'Hinterland' box, you'll enable autocompletion on Jupyter Notebooks and would be able to write code like in your favorite editor.
Follow 3 steps: In Terminal
pip install jupyter_contrib_nbextensions jupyter contrib nbextension install --user jupyter nbextension enable varInspector/main
after this you will see "Vaildating: ok" Now you can open jupyter notebook you will see the require changes
Update Jan 2021
I was seeing this issue using the latest from pip packages.
Turns out it was related to: https://discourse.jupyter.org/t/the-static-notebook-js-mathjaxutils-js-is-missing/7303
Basically, jupyter-notebook moved a .js file in a recent update causing the extensions tab to no longer appear.
Reverting to an older version works-around the issue:
pip install notebook==6.1.5
Also note that a substantial number of the extensions aren't officially supported by the 6.x version. So you may be better off reverting to 5.x until your desired extensions are 'officially' supported:
pip install notebook==5.7.10
