@dbroockman I'm not able to reproduce these failures in force_save locally. Are you using JupyterLab, Retrolab, or the old Jupyter notebook interface on the hub?

[dbroockman]

Same, it works for me locally. Errors are appearing on Berkeley Datahub. Here's an example link: https://r.datahub.berkeley.edu/hub/user-redirect/git-pull?repo=https%3A%2F%2Fgithub.com%2Fdbroockman%2FPS3-SP24-Public&branch=main&urlpath=tree%2FPS3-SP24-Public%2Fw2%2Fw2a1v2%2Fstudent%2FWeek2_Activity1.ipynb

Unfortunately I can't access the hub since I no longer have a canvas account. Can you share a screenshot of the full page so I can figure out which you're using?

[chrispyles]

Can you open Help > About RetroLab and send a screenshot? maybe the issue is related to the specific version of retrolab.

[chrispyles]

I assume it's a more recent version than 0.2.2 (mine), since after upgrading to the latest version I am now able to reproduce. Will look into it.

[dbroockman]

Thanks. In Terminal pip show retrolab gives me package not found.

My help menu also does not have an About Retrolab option:

[chrispyles]

Can you select "About Jupyter Notebook" and send a screenshot?

I think this is an upstream bug in Jupyter Notebook. opened jupyter/notebook#7225

[chrispyles]

Until that gets fixed, I've come up with a rather hacky solution that involves installing a JupyterLab extension that leaves a hook ottr can call to force-save the notebook. Since there's already an Otter-Grader lab extension I'm going to reuse it. Will let you know when the version that needs to be installed on the hub is available.

@dbroockman I've sent off v1.5.0 of ottr to CRAN; I'll follow up once it's installable. v1.5.0 will require the Python package ottr_force_save_labextension to be installed in order for force-save to work, so when you make the request to upgrade ottr on the hub, make sure to also ask for package to be installed.

[chrispyles]

ottr v1.5.0 is now installable from CRAN and github, so feel free to open an issue on berkeley-dsep-infra/datahub to install it and ottr_force_save_labextension

[dbroockman]

Thank you!
