kernel died unexpectedly

[matt]

When I start an ipython session now, it works for a small amount of time (0-2 minutes), then fails with

 It seems the kernel died unexpectedly. Use 'Restart kernel' to continue using this console.

Then Windows makes me end the task and that same line keeps appearing in the Ipython console.  I can look into it further, but nobody else is seeing this?

Have you checked that the kernel attached to the console is still alive?
I mean, in the console (not IPython console) plugin?

Everything else in spyder still functions as normal (I believe this would not be the case if the console kernel had died) just the Ipython console gives up, if I restart it with your new tool, it seems to work fine for a while, then dies again.  How do I check if kernel attached to the console is still alive?

Please select the Console plugin and check that a tab called "IPyKernel (23987)" (where the number is the same as the one of console you see has died) and check that is not greyed out.

It is greyed out, that is what has died and has to be restarted.

[Carlos Córdoba]

Did you send some heavy/strange computations from the IPython console? or it just dies with no apparent reason?

I don't even have to be using it for it to die...I was playing on the internet.

[Carlos Córdoba]

What happens if you run ipython alone with

ipython qtconsole

from the terminal? Are you seeing the same behavior?

Ipython qtconsole by itself will run all day.  Possibly I should mention I am on a windows 7 64 bit machine.  The amount of time before it dies in Spyder can be rather long, 5-10 minutes even.

[Carlos Córdoba]

Do you seem something printed on the Internal Console plugin or on the kernel tab that shows why it died? Or could you use 'hg bisect' to try to detect what change introduced the problem? Also, if you updated IPython lately try to run 'ipython qtconsole' next to Spyder to see if thet show the same behavior.

Jed, I think you use a 64 bit Win 7 machine. Could you confirm this issue?

i don't know if this is the same problem but

on osx using the latest ipython (both qtconsole and notebook works fine)

i installed latest hg version of spyder, when i run the ipython from inside spyder with : 

open an  ipython console 

 i got :

I do have Win 7 64-bit, but I'm running 32-bit Python. I cannot reproduce this behavior. I have yet to see a kernel self destruct like this.

Hi Massimo,

That's not the same problem. It seems you're using IPython 0.13dev but you need to update to 0.13beta1 to make Spyder work again with the latest IPython. A simple git fetch for IPython should solve the problem.

Cheers,
Carlos

Thanks Carlos,

git pull and problem fixed

so spyder-dev and ipython-dev are pretty i sync, grat job on both sides! :)

Well, good news bad news...I can no longer reproduce this error.  After rebooting my machine it no longer occurs, so chalk it up to a windows glitch I guess.  If it starts happening again I'll do a bisect on it.

[matt]

A little more info on this.  It seems to be a Pyside problem.  I can recreate this issue when using Pyside, but not when using PyQt

Hi Carlos, I am facing same problem,

But i have given a heavy computation command, is it that reason I am getting the error "It seems the kernel died unexpectedly. Use 'Restart kernel' to continue using this console." 

[Carlos Córdoba]

I don't know. Does the kernel die when you run simple computations or not?

I have an issue which might be related. I get exactly the same problem when using matplotlib in Ipython: "It seems the kernel died unexpectedly. Use 'Restart kernel' to continue using this console."

 If I run it in a normal console inside spyder it dies - if I run it in a normal console outside spyder there is no problem.

To reproduce run:
"""
from pylab import *

plot([1], [2])
"""

My configuration is:
Python 3.5.1 |Anaconda 2.2.0 (64-bit)| (default, Feb 16 2016, 09:49:46) [MSC v.1900 64 bit (AMD64)]

I have not tried it on my linux machine yet, but this seems to be a problem starting recently, maybe due to an upgrade of Anaconda.

[Carlos Córdoba]

Are you using the Tk backend for matplotlib?

Hi Carlos,

I'm getting "kernel died" errors on my IPython Spyder console too (Python 2.7, Spyder 2.3.8, Windows 7), no computations but just as soon as I start up the program. Tried resetting Spyder to defaults and also installing the latest version of Anaconda but no luck. Any tips?

Many thanks,
Will
