[pymvpa] SMLR shared library not found

[Thorsten Kranz]

Hi amit,

you are in the source-directory of pymvpa. Within this is a directory 'mvpa'.

If you open ipython or python and type

import mvpa

or

from mvpa.suite import *

then python takes the mvpa-subdirectory as the place from where is
imports the mvpa-package. This won't work, at least for SVM / SMLR,
that use C-code bindings that have to be compiled.

But don't waste your time compiling and trying to install all this.

Just go to another directory! do:

cd /home/amid
ipython
from mvpa.suite import *

and everything should work.

Greetings,
Thorsten
