Hi guys, I don't understand why now, after I save an image when it is prompted out, the image is not saved and it closes automatically and on the terminal appears segmentation fault. this is what my terminal shows: [gs66-stumbras:~/Desktop] gbrambil% python Bdipole.py Bdipole.py:52: RuntimeWarning: divide by zero encountered in divide lwb = 5/(np.log10(modB.max()/modB)) Bdipole.py:55: RuntimeWarning: divide by zero encountered in divide lwe = 5/(np.log10(modE.max()/modE)) Segmentation fault Thanks Gabriele |

What happens when you edit your program to avoid dividing by zero? -p — Sent from Mailbox On Thu, Mar 19, 2015 at 10:14 AM, Gabriele Brambilla <gb....@gm...> wrote: > Hi guys, > I don't understand why now, after I save an image when it is prompted out, > the image is not saved and it closes automatically and on the terminal > appears segmentation fault. > this is what my terminal shows: > [gs66-stumbras:~/Desktop] gbrambil% python Bdipole.py > Bdipole.py:52: RuntimeWarning: divide by zero encountered in divide > lwb = 5/(np.log10(modB.max()/modB)) > Bdipole.py:55: RuntimeWarning: divide by zero encountered in divide > lwe = 5/(np.log10(modE.max()/modE)) > Segmentation fault > Thanks > Gabriele |

The warnings probably have nothing to do with the issue at hand. Try this. Install the package "faulthandler" and add the appropriate lines to your Bdipoly.py script and run it again. That way, we can get a traceback and find out where it is segfaulting from. http://faulthandler.readthedocs.org/en/latest/ Ben Root As a side-note: faulthandler is part of the standard library as of 3.3! Neat!

Actually Paul Hobson was right. Now it works. Thanks Gabriele On Thu, Mar 19, 2015 at 1:19 PM, Benjamin Root <ben...@ou...> wrote: > The warnings probably have nothing to do with the issue at hand.

well, that still doesn't explain the segfaults. NaNs shouldn't cause matplotlib to crash upon saving. I would still be interested in a stacktrace.
