[matplotlib-devel] PyQt4 in Matplotlib v2.0.0
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.

no, pyqt5 is not a dependency for matplotlib. this looks like a conda packaging issue. Side note: the sourceforge mailing list is deprecated. Please use the python.org version instead (you'll have to re-register).

Re: [matplotlib-devel] PyQt4 in Matplotlib v2.0.0
It appears that the build of matplotlib in conda-forge does not require pyqt5: https://github.com/conda-forge/matplotlib-feedstock/blob/master/recipe/meta.yaml So in your case, I would do: conda remove pyqt5 matplotlib conda install --channel=conda-forge matplotlib On Thu, Feb 2, 2017 at 8:48 AM, Benjamin Root wrote: > no, pyqt5 is not a dependency for matplotlib. this looks like a conda > packaging issue. > > Side note: the sourceforge mailing list is deprecated.
