Jupyter kernel started crashing

See original GitHub issue

Applies To

  • Notebooks (.ipynb files)
  • Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

The Kernel crashed while executing code in the the current cell or a previous cell. Please review the code in the cell(s) to identify a possible cause of the failure. Click here for more info. View Jupyter log for further details.

Canceled future for execute_request message before replies were done

I have a code cell I’ve run successfully in the past that started bringing the whole server down recently. I think it may have started after upgrading some packages in my venv. Tried downgrading those again which didn’t help.

I can repro the same kernel crash even outside VS Code, i.e. if you run the same code in Jupyter Notebooks the kernel crashes.

Should have tried that myself. 🤦

Just to check, do you have any advice how to debug this? Is there some hidden stack trace somewhere?
