Interrupt/Restart Slow or Not Working

[claudiaregio]

I have a hunch that interrupt not working is coming from the cell level based on previous feedback and my own experience as well. The cell level interrupt sometimes just doesn't work and requires restarting the entire kernel.

My understanding is that sometimes the kernel cannot be restarted or interrupted because it's executing code outside of the Python kernel proper. In these cases, the external code has to finish running before an interrupt will be honored.

Wouldn't this problem also happen in Jupyter Lab and Jupyter Notebook?

Interrupt is handled by the jupyter extension

Interrupt is slow or doesn't work on windows, this is a know issue for Windows (nothing much we can do)
Restart is slow is documented here #7849

Interrupt button will be moved to VS Code core #7661
Closing as a duplicate of #7849
