http://bugzilla.opensuse.org/show_bug.cgi?id=1136643 Bug ID: 1136643 Summary: IPython console in spyder3 breaks after an exception error Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development Assignee: bnc-team-screening@forge.provo.novell.com Reporter: rodolfo.am25@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 806259 --> http://bugzilla.opensuse.org/attachment.cgi?id=806259&action=edit journalctl -f log during the reproduction of the bug in spyder3 I have found this bug occurring anytime an error exception is raised in the IPython console. After an exception the console breaks and any further commands output the message "ERROR: execution aborted". Reinitializing the console (Restart kernel in spyder3 GUI) restores functionality but does not remove the bug, that is, after a new exception any following command break with the message "ERROR: execution aborted". I installed spyder3 from the Main Repository (OSS) in a machine recently upgraded from Leap 15.0 to 15.1. I performed the upgrade via YaST run from a bootable drive. After the first boot to Leap 15.1 I performed a zypper up followed by spyder3. Installed versions on Leap 15.1 spyder3 3.2.8-lp151.3.3 python3-jupyter_ipython 7.4.0-lp151.1.1 python3-jupyter_ipykernel 5.1.0-lp151.1.23 While the spyder3 version is the same in Leap 15.0 and 15.1, the system upgrade included an update of IPython from 6.2.1 to 7.4.0 and an update of the IPython kernel component (python3-jupyter_ipykernel) from 4.8.2 to 5.1.0. This may be connected to this present bug. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1136643 http://bugzilla.opensuse.org/show_bug.cgi?id=1136643#c1 --- Comment #1 from Rodolfo Marques --- I did a further inspection in order to recreate the problem and found out that this problem appears after installing matplotlib plotting backends. Here's what I did: 1) First I uninstalled all previously installed matplotlib components: python3-matplotlib-2.0.2-lp151.3.6.x86_64 python3-matplotlib-cairo-2.0.2-lp151.3.6.x86_64 python3-matplotlib-gtk3-2.0.2-lp151.3.6.x86_64 python3-matplotlib-tk-2.0.2-lp151.3.6.x86_64 python3-scikit-learn-0.20.2-lp151.1.8.x86_64 NOTE: at this point the interactive console behaves normally, i.e. no bug 2) Reinstalled python3-matplotlib: python3-matplotlib-2.0.2-lp151.3.6.x86_64 python3-matplotlib-tk-2.0.2-lp151.3.6.x86_64 (recommended) After installing these components the interactive console in spyder crashes due to matplotlib backends not being found. Here is the error output: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/spyder/utils/ipython/spyder_kernel.py", line 498, in _set_mpl_backend get_ipython().run_line_magic(magic, backend) File "/usr/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 2307, in run_line_magic result = fn(*args, **kwargs) File "", line 2, in matplotlib File "/usr/lib/python3.6/site-packages/IPython/core/magic.py", line 187, in <lambda> call = lambda f, *a, **k: f(*a, **k) File "/usr/lib/python3.6/site-packages/IPython/core/magics/pylab.py", line 99, in matplotlib gui, backend = self.shell.enable_matplotlib(args.gui) File "/usr/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 3384, in enable_matplotlib pt.activate_matplotlib(backend) File "/usr/lib/python3.6/site-packages/IPython/core/pylabtools.py", line 313, in activate_matplotlib import matplotlib.pyplot File "/usr/lib64/python3.6/site-packages/matplotlib/pyplot.py", line 115, in <module> _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup() File "/usr/lib64/python3.6/site-packages/matplotlib/backends/__init__.py", line 32, in pylab_setup globals(),locals(),[backend_name],0) ModuleNotFoundError: No module named 'matplotlib.backends.backend_gtk3agg' 3) Installed the following packages: python3-matplotlib-gtk3-2.0.2-lp151.3.6.x86_64 python3-matplotlib-cairo-2.0.2-lp151.3.6.x86_64 (recommended) After this the error when starting the interactive console in spyder disappears but the original bug appears. ADDITIONAL NOTE: I created a simple Python environment installing only spyder, ipython (pip install spyder ipython), tested it and it was ok. After installing matplotlib I received error messages for the cairo and GTK backends. Installed pycairo and pygobject from pip and the original bug was recreated in spyder's interactive console. -- You are receiving this mail because: You are on the CC list for the bug.

I tried to reproduce this bug with the following matplotlib, spyder and ipython packages installed:

But IPython starts fine in Spyder3

Do you have any other repositories enabled?

Yes, I have an OBS repo enable from the user Dead_Mozay (https://download.opensuse.org/repositories/home:/Dead_Mozay/openSUSE_Leap_15...) to install the pycharm-community IDE. However I put this repo with a lower priority relative to the main repos. Meanwhile I installed a fresh Leap 15.1 installation on a virtual machine, updated it and installed every component you listed in your test in the same order. The IPython in spyder actually behaved fine! I enabled the Dead_Mozay repo, installed pycharm-community (with its dependencies), and no problem! I am quite puzzled but I think of two hypothesis: 1) Something went wrong during the upgrade from Leap 15.0 to Leap 15.1. 2) I messed up something while enabling certain repos to get software I wanted. The latter is probably the most likely and although I try to be careful, sometimes stuff happens. At this point I find it hard to pin point when the problem started to happen. -- You are receiving this mail because: You are on the CC list for the bug.
