[matplotlib-devel] PyQt4 in Matplotlib v2.0.0

[Osborn, R. <ro...@an...>]

I just created a new conda environment with Matplotlib included, and it duly installed matplotlib: 2.0.0-np111py27_0. It installed PyQt5 by default, whereas I need PyQt4, but when I installed PyQt4 (conda install pyqt=4), it automatically downgraded Matplotlib to 1.5.1.
--------
The following packages will be DOWNGRADED due to dependency conflicts:

    matplotlib: 2.0.0-np111py27_0 --> 1.5.1-np111py27_0
    pyqt:       5.6.0-py27_2      --> 4.11.4-py27_4    
    qt:         5.6.2-0           --> 4.8.7-4
--------
Is PyQt5 really a dependency for Matplotlib v2? I have been testing release candidate versions of Matplotlib v2 without any problem. This will cause headaches to my users who want the latest features.
