As far as I know, MNE-Python cannot read .mgz surface files. To show a 
..w file on an inflated surface you can do (assuming you have 
activity-lh.w and activity-rh.w):

stc = mne.read_source_estimate('activity')
stc.plot(subject=subject, subjects_dir=subjects_dir, hemi='lh')

The first call will read both .w files and the second will show the 
activity on the left hemisphere. Note you need MNE-Python 0.6 or newer 
for this.

I hope this helps,

Martin
