Installation: nbgrader menus don't show up in jupyterhub

kliegr commented 2 years ago

Operating system

Ubuntu 20.04.5 LTS

`nbgrader version`

0.8.1

`jupyterhub version` (if used with JupyterHub)

1.5.0 20220918101831

`jupyter notebook --version`

6.4.12

Expected behavior

after pip install nbrader the Jupyter hub web UI contains Formgrader, Courses and Assignment menus

Actual behavior

Neither of the nbgrader-specific menus shows up

Steps to reproduce the behavior

I have also tried installing with "sudo" and activating the server extensions manually as described in https://nbgrader.readthedocs.io/en/stable/user_guide/installation.html with no result. No error is reported during the installation or activation of the extensions.

Thanks for reporting this issue.

Are you running it in Classic Notebook or JupyterLab ?

Can you copy the return of the following commands :

jupyter nbextension list

and

jupyter labextension list

Thanks for looking at this. We are running it JupyterHub, where we get:

But we would expect (and get on another older installation):

The results of the commands (on server where the menus don't show up):

Look like the extensions are enabled.

Do the extensions work if you run jupyter notebook or jupyter lab, without going through JupyterHub?

If it works, maybe you can take a look at the demos directory for the settings of nbgrader with JupyterHub.

Hi, we resolved this. It looks like this was caused by a mismatch between the version of nbgrader and the changes in configuration files between nbgrader versions 0.7.1 a 0.8.0.

jupyter / nbgrader
