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,
Just a guess, but the pyMVPA site specifically mentions using version
2.5, and whenever I have issues with a new package, I go back to the
installation documentation and follow it closely as it's typically
written by an experienced user while installing and yields a functioning
implementation. I'd reinstall and pay close attention to the version
numbers and dependencies.
http://www.pymvpa.org/installation.html#macos-x
Then, always check if there's a user group for the package. Diagnosing
installation problems of specific packages and related dependencies are
rarely an area of expertise outside the users of the package. Join the
mailing list.

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.
