Autosave not working

[kylekehrer]

Description

Hello, I recently switched over from PC to Mac and have installed jupyter notebook as my primary python coding environment. It's working great so far, except that the files no longer autosave as expected. There are no error messages in the terminal I open Jupyter notebook from, and so far the only hint to the issue is that when I try to run %autosave 120 (for example) in one of the cells, I receive the error message

Javascript Error: IPython is not defined
Autosaving every 120 seconds

No matter the time I pass as an argument to %autosave, it will never autosave at that frequency. I've tried searching this problem online, which included possible fixes as deleting ~/.ipynb_checkpoints, running jupyter notebook as root, and explicitly adding ~.ipynb_checkpoints to the jupyter notebook config file as the place to store checkpoints, but nothing has worked. I can cmd+S to save the files just fine, but it would be nice to have the autosave feature working in case I forget when I close a notebook.

Reproduce

1. Go to terminal and type jupyter notebook
2. Click on or create any .ipynb file
3. Observe top of window
4. Notice that it never autosaves/creates a checkpoint on its own, and no error message appears

Expected behavior

Context

• Operating System and version: MacOS Sequoia 15.1
• Browser and version: Firefox 132.0.1
• Jupyter Notebook version: 7.2.2

[RRosio]

Thank you for opening this issue @kylekehrer! The Autosave interval option is available in the settings editor so you could try setting it there (search for autosave in the Settings Editor to find the option). You can find more information on the error you are receiving in the following issue: jupyterlab/jupyterlab#5660

[RRosio]

Currently the %autosave magic is not documented in the IPython docs: https://ipython.readthedocs.io/en/stable/interactive/magics.html.

Note: jupyterlab/jupyterlab#7083 is more inline with providing some background on this behaviour.
