Google collab interactions

Is is possible to activate the validate form button in google collab ? Can I ask the students to complpete the assignments in google collab, export and import it for grading on nbgrader.

Operating system

nbgrader --version

jupyterhub --version (if used with JupyterHub)

jupyter notebook --version

Is there any chance of nbgrader and Google colab working together at some point in the future? I’ve been running JupyterHub on my own kubernetes cluster so I can use nbgrader, but this can be expensive and Google colab offers some nice features.

The notebook is just a file on some storage system, accessible to the user. nbgrader sets a ‘read-only’ metedata on cells, but it’s up to the editor (jupyter notebook server, colab) to use it or not. For some fun, you can edit cell metadata in normal jupyter notebook/lab and make any read-write if you want. Or open the notebook in a raw text editor…

nbgrader might re-insert the original content back when it is being re-processed, and it definitely will for hidden solutions. If you want some sort of assurance, it has to be at this level. This is the theory at least, I know it does something but upon looking a bit I can’t immediately convince myself it does for all of the cases I have in my mind. Has someone looked into this?

nbgrader isn’t a captive editing system.

But for the original question… I have a teacher that tells students they can download notebooks from our jupyterhub, upload to colab to work, and transfer them back to jupyterhub to submit (they they have a few other options). There are ways that colab can break things, but when you realize what goes on under the hood it works. I also use nbgrader on a multi-node system with a shared filesystem, it works if you manage user IDs well (and some people manage without, but I wouldn’t recommend that). As far as students work, the notebooks are just notebooks. Submitting/receiving is another matter, depending on your needs you may be happy with the current situation or you may not be. Remember that original nbgrader relied on some other way of distributing notebooks to students, if you build something that way colab works like normal.
