To make nbgrader work on our JupyterHub, we had to make some adjustments to the extension and the hub itself.
⚠️ Please do not use any other self-installed version of nbgrader!
If you wish to conduct a course on JupyterHub, please sign up with our support. Provide us with the course name and send us a list of instructors and students. We will then create the corresponding groups for you.
