Package: python-matplotlib
Version: 2.2.3-5
Severity: important
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
trying to run a program which uses python-matplotlib and got the following
crash:
File
"/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtkagg.py", line
12, in <module>
from matplotlib.backends.backend_gtk import (
File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtk.py",
line 38, in <module>
from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK
File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gdk.py",
line 29, in <module>
from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array
ImportError: No module named _backend_gdk
* What exactly did you do (or not do) that was effective (or
ineffective)?
Due to bug#889137 I modified one program line from this:
from matplotlib.backends.backend_gtkagg import NavigationToolbar2GTKAgg
to this:
from matplotlib.backends.backend_gtk3agg import
NavigationToolbar2GTKAgg
* What was the outcome of this action?
Another crash:
File
"/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtk3agg.py", line
9, in <module>
from . import backend_agg, backend_gtk3
File "/usr/lib/python2.7/dist-packages/matplotlib/backends/backend_gtk3.py",
line 19, in <module>
from ._gtk3_compat import GLib, GObject, Gtk, Gdk
File "/usr/lib/python2.7/dist-packages/matplotlib/backends/_gtk3_compat.py",
line 34, in <module>
raise ImportError("The Gtk3 backend requires PyGObject or pgi")
ImportError: The Gtk3 backend requires PyGObject or pgi
* What outcome did you expect instead?
The program to run.
The program is not mine, I am not familiar with python ecosystem, so I am
completely lost.
I do not know if that's a Debian's fault to purge gtk2 support
or matplotlib is unable to use gtk3 or if it is being called in a
wrong way.
I did install python-gi and python-gobject-2.
I have no idea what is PyGObject, so at least the error message is
useless/misleading.
