can't install pyqt

I don't see how to install pyqt into intelpython environment:

conda install pyqt --channel=intel

Did you mean one of these?

pytz

You can search for this package on anaconda.org with

anaconda search -t conda pyqt

A workaround is to:

A workaround is to:

conda remove freetype2

You will switch some packages from intel to continuum, including matplotlib, but you will still have intel numpy/scipy

We are working with continuum to resolve depedences that make it difficult to mix packages.

OK, I did

OK, I did

conda remove freetype2

Then:

conda install pyqt

The problem is a version

Robert_C_Intel — Fri, 13 May 2016 19:45:22 GMT

The problem is a version conflict between the packages we provide and the requirements of pyqt from anaconda. If you start from miniconda and create an intel python environment:

 conda create -n idp3m intelpython3_core

Then I am able to install pyqt with no conflict. If I start with Intel python installer, then there is a conflict on the versions of libpng, but uninstalling freetype2 removes the conflict and installs pyqt. I think you have a different combination of packages and the conflict is different. If you can tell me how to create an conda environment that shows the problem, then I can reproduce and track it down.

We have asked Continuum to update their package to also accept libpng 1.6.18, instead of only 1.6.17, which would fix the problem that I see. We are also looking at more general solutions to avoid version conflicts in the future.

The original problem was that

Becker__Neal — Mon, 16 May 2016 13:42:32 GMT

The original problem was that when I tried to plot with matplotlib, I got no screen output (and now error message).

I did notice that

%matplotlib

said setting output to Agg.

Usually, I would see

In [32]: %matplotlib
Using matplotlib backend: Qt5Agg

So I thought maybe the problem was caused by pyqt not being installed.

Otherwise, my original problem is still that matplotlib doesn't seem to produce any screen output.

If you download intel python

Robert_C_Intel — Mon, 16 May 2016 15:34:42 GMT

If you download intel python from intel and activate the root environment, it works. If you create a conda environment, with intelpython3_core and matplotlib then plotting does not work--it silently exits for me.

I think there is a missing dependence that is only uncovered when you install packages individually. I need to investigate some more.
