I am a user of latest version of intel distribution for python. But I find problem of using matplotlib.
My OS is Ubuntu 64bit 16.04. Because I don't like the default backend of matplotlib, so I chang it from WebAgg to Qt4Agg and I get the flowing error messages:

I install intel distribution for python using conda.
I install idp on the latest version debian, I got the "Fontconfig error: Cannot load default config file" too.

Hello,
Thanks for bringing this issue to our attention. I was able to install Continuum's pyqt package into a conda environment with Intel Python and successfully change the backend to Qt4Agg.
# Create a conda environment with Intel Python and Intel's matplotlib and tornado packages $ conda create -n mpl -c intel --override-channels matplotlib tornado # Activate the environment $ source activate mpl # Install Continuum's pyqt package into the Intel environment $ conda install pyqt=4 # Run python, change the backend and show a simple plot $ python >>>import matplotlib >>>matplotlib.use('Qt4Agg') >>>import matplotlib.pyplot as plt >>>plt.plot([1,2,3,4]) >>>plt.show()
I did see the Fontconfig error you pointed out, but matplotlib seems to work fine otherwise. Are you able to see plots after you get the Fontconfig error?

Dear Christopher H thanks for your replying. I will test matplotlib according to your instruction.
Now if I install intel distribution for python by the pack download from intel web site. I do not using conda to manage python environment. when I use pip to install pyqt4, however, there is no pack name pyqt4 to install. How can I install pyqt package?
And why the intel distribution for python matplotlib do not use Qt4agg as the default backend?

Hi Guo,
To set your default backend to Qt4Agg, you can modify the matplotlibrc file located in <PY_INSTALL_PATH>/lib/python<VERSION>/site-packages/matplotlib/mpl-data/matplolibrc.
Change
backend : WebAgg
to
backend : Qt4Agg
If you already have a matplotlibrc file in ~/.config/matplotlib, it will read that one first, so you can set the default backend there instead of the site-packages folder.
After you've set the backend, you should see
python -c "import matplotlib; matplotlib.get_backend()" > 'Qt4Agg'
I hope that helps.
Chris
