Expected behavior
The command nbgrader autograde --force “Homework XX” --student abc123 should work for well-formed notebooks.
Actual behavior
About ~20% of the time it fails with TimeoutError: Timeout waiting for IOPub output Running the same notebooks with the web interface works about 50% of the time. If I keep trying it works eventually.

It’s not consistent with any particular notebook. What I’ve since found is that setting my PC’s power mode to “Best Performance” (on Windows 10) makes the issue completely disappear.
It might have something to do with how the timeout is calculated. It’s not just that it takes too long. When it does fail, it usually does it within a few seconds.
I also run into the issue
Timeout waiting for IOPub outputfor some of my student submissions. I haven’t looked into it in enough detail to find out what is causing it. It occured with student submissins that generated a lot of outputs (plots, print statements, etc.). It might be related, but it could also be a coincidence.
