[yt-users] inconsistent backend when using yt interactively

[Slavin, Jonathan]

Hi all,

I've been using yt for some time, but mostly as a way to access AMR data
generated by FLASH.  Just now I tried using the (new, I think) interactive
plotting capabilities of yt by doing:
yt.toggle_interactivity()
ds = yt.load(hdf5_file)
p2d = yt.plot_2d(ds,'temperature')

When I toggle interactivity I get the message:
Using matplotlib backend: Qt5Agg

​but when I try to generate the 2d plot I get a bunch of error messages
ending with:
​/export/slavin/python/anaconda/lib/python2.7/site-packages/yt/visualization/base_plot_types.pyc
in _set_canvas(self)
    120                 mod = __import__('matplotlib.backends', globals(),
locals(),
    121                                  [backend_dict[key][0]], 0)
--> 122                 submod = getattr(mod, backend_dict[key][0])
    123                 FigureCanvas = getattr(submod, backend_dict[key][1])
    124                 if len(backend_dict[key]) > 2:

AttributeError: 'module' object has no attribute 'backend_gt5agg'

​So somehow the backend got changed to, or was assumed​ to be, gt5agg
rather than qt5agg.  It's especially weird in that I don't think there even
is a gt5agg backend.  Seems a mixture of qt5agg and gtkagg.  Any ideas?

Jon
