Quick one. Conda is indeed nice, but there is absolutely no need to install PyMVPA via conda on NeuroDebian since we provide all necessary Debian packages there.

sudo apt-get install ipython python-mvpa2

To install ipython and pymvpa2

In python or ipython you need to

import mvpa2

Not pymvpa2

Also, whenever you enter the NeuroDebian VM for the first time, in the
last dialog of the welcome wizard there is an option for "PyMVPA
Tutorial" selection.  This will also install
python-mvpa2-doc python-mvpa2-tutorialdata packages which would provide
you all necessary docs/notebooks and data
