nbgrader with the-littlest-jupyterhub: Can't use formgrader for release and collect assignment.

[DSqiansun]

Hello,

I followed the tuto https://tljh.jupyter.org/en/latest/install/amazon.html, and installed the-littlest-jupyterhub in AWS EC2. Then I installed nbgrader in jupyterhub terminal. But the courses can't be released

Operating system

Ubuntu 18.4

nbgrader --version

nbgrader version 0.5.5

jupyterhub --version (the littlest JupyterHub)

0.9.4

jupyter notebook --version

5.7.0

Expected behavior

Formgrader should be able to release and collect assignment

Actual behavior

I already set the course id in nbgrader_config.py but formgrader have an error message "The course id has not been set in nbgrader_config.py. The "release" and "collect" functionality will not be available. Please see the documentation on Setting Up The Exchange for instructions." and it cannot release and collect assignment

setup

install jupyterhub

https://tljh.jupyter.org/en/latest/install/amazon.html

install nbgrader in terminal

sudo -E pip install nbgrader
sudo -E jupyter nbextension install --sys-prefix --py nbgrader --overwrite
sudo -E jupyter nbextension enable --sys-prefix --py nbgrader
sudo -E jupyter serverextension enable --sys-prefix --py nbgrader

then, i set nbgrader_config.py in home/username

Hi,

I have the exact same issue and no proper solution, yet. However, what I did do (and still testing this out) is to login JupyterHub as an admin user, open a terminal, and use nbgrader from the console. Everything you want to do is doable through the terminal. If I create an assignment (the basic example one (using nbgrader quickstart), I can then perform the assign and release tasks. It then properly distributes the assignments and when I log in as any other user it is listed under the Assignments tab. I'm also able to collect, edit and submit them and subsequently collect. See the command lines options listed here.

It's definitely not the way we would like to work with nbgrader and I'm not looking forward to instructing my colleagues on how to use it like this, so I'm hoping it'll receive a proper fix.

Did you try creating the /home/teacher-user/.jupyter/nbgrader_config.py file as mentioned in the nbgrader docs?

@DSqiansun

Have you tried to set up the nbgrader_config.py as per https://nbgrader.readthedocs.io/en/stable/configuration/nbgrader_config.html. It says to make three copies of the file.

@jhamrick I am facing an issue that when I try to release the assignment:

nbgrader release_assignment ps1 --force --debug

It releases the assignment without errors but to the location (/home/jupyter-tljh-admin/course_id/outbound/ps1) but not to the shared location /srv/nbgrader/exchange:

[ReleaseAssignmentApp | INFO] Overwriting files: /home/jupyter-tljh-admin/course_id ps1
[ReleaseAssignmentApp | INFO] Source: /home/jupyter-tljh-admin/course_id/release/./ps1
[ReleaseAssignmentApp | INFO] Destination: /home/jupyter-tljh-admin/course_id/outbound/ps1
[ReleaseAssignmentApp | INFO] Released as: /home/jupyter-tljh-admin/course_id ps1

The folder /srv/nbgrader/exchange has write persmissions

Please suggest, what could be issue?

I met same question and set every nbgrader config file i can find, but i could not figure out this question.
