Any way to kill/restart the IPython kernel?

Every once in a while my ILeo IPython kernel becomes unresponsive. The IPython window itself will look normal but when trying to execute anything from that window or through ipython-exec I get nothing in return.

I haven't submitted this as a bug because I have no idea when this is happening to the kernel and therefor can't reproduce it.

In the meantime I was wondering if there is any way to kill and restart the kernel?

Have you tried ipython-new?

Otherwise, isn't this question really an IPython issue?

Yes, have tried closing the IPython window and use ipython-new, to no avail. The thing is IPython doesn't become unresponsive on it's own. I've only had issues with ILeo, and only within the past couple months I would say... I think it started after the upgrade to Jupyter/IPython 4.

Not sure how to proceed with this. The interface code is quite simple, although it obviously could have bugs.

You can enable more verbose tracing by setting Leo's --debug option. It will probably be easier for you to

enable tracing by hand in ileo.pylab_kernel. Higher levels are quieter so perhaps level 0 would be reasonable.

Please let me know whether this provides any insights. Btw, it's good to know somebody is actually using the IPython bridge.

I will do it manually by hand, so I don't get noise from elsewhere.

I am a huge fan of the IPython bridge. Having "interactive" access to Leo's internals is pretty great, sort of feels like I'm "hacking" into Leo.
