问题
I'm using jupyter notebook for a while. Often when I tried to stop a cell execution, interrupting kernel did not work. In this case, what else can I do, other than just closing the notebook and relaunch again? I guess this might be a common situation for many people. thanks a lot.
回答1:
If you're ok with losing all currently defined variables, then going to Kernel > Restart will stop execution without closing the notebook.

Currently this is an issue in the github jupyter repository as well, https://github.com/ipython/ipython/issues/3400 there seems to be no exact solution for that except killing the kernel
回答3:
Put in comment (highlight and press Ctrl-/) the instruction(s) responsible for running -- or, faster, comment the whole cell -- and re-run the cell (Ctrl-Enter). This will stop running and of course the output. You can then un-comment the affected part. This is much less painful than killing and restarting the kernel.
(Note that just clearing the output with [Esc]+'O' won't stop it.)

If the iPython kernel did not die, you might be able to inject Python code into it that saves important data using pyrasite. You need to install and run pyrasite as root, i.e. with sudo python -m pip install pyrasite or python3 as needed. Then you need to figure out the process id (PID) of the iPython kernel (e.g. via htop), say 3873. Finally, write a script that saves the state for example to a pickle in a file inject.py and inject it into the process as follows:
sudo pyrasite 3873 inject.py
You may need to enable dtrace first like so:
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
