[Mne_analysis] Problem installing mayavi

[Andrew R. Dykstra]

Hi Dirk,

An alternative to what Chris proposed that may be a bit simpler is if you
issue the following commands, from your home directory, in the specified
order (after having downloaded and installed conda):

conda install mayavi scipy matplotlib scikit-learn jupyter spyder (and any
other packages)
pip install PySurfer
git clone git://github.com/mne-tools/mne-python.git
cd mne-python
python setup.py develop

This prioritizes mayavi, and unfortunately means that you'll be stuck with
matplotlib version 1.5 (as opposed to version 2). I think the conflict may
be arising because the newest version of matplotlib (and maybe some other
stuff as well) uses qt5, whereas mayavi is still using qt4. The way I got
around this was to revert to matplotlib 1.5, thus avoiding the qt4/5
conflict.

HTH,
Andy
