I am very much new to python, and thus I am likely to feel stupid
about asking. But I need to get past this to continue with my work.
I need pyMVPA module to run some analysis on fMRI data, but as a start
I want to at first play around with the sample data provided on pyMVPA
website. I have downloaded Python2.6, my operating system is Mac
Leopard (i get a depracation warning when I try to >>> import mvpa,
which is not the problem, however, when I attempt to use the following
line
>>> import mvpa.suite as mvpa
which i assume to mean the same thing, I dont get deprecation warning,
but I do get a bunch of errors as follows:
>>> import mvpa.suite as mvpa
Traceback (most recent call last):

-----
I am not sure why OSError is popping and I am sure I am doing
something wrong, I just do not know enough to pinpoint what exactly.
Any feedback is appreciated. And I do once more apologize for asking
very stupid questions.
