I'm having some problems with the use of multi_array's with python. What 
I'm trying to do is to export some functions that create multi_array's 
and pass these multi_array's to other functions that will extract other 
array's from them and display them.

So you see I can't use my code, what am I doing wrong?
    

You didn't export multi_array<double, 2> to Python. If you just want to
pass the multi_array's around without manipulating them, it's enough to
export it without any functions:

  class_<multi_array<double, 2> >("multi_array_2d");

If you want a more complete binding, there's binding code for
boost::multi_array queued for inclusion on the CVS. It's currently on a
branch:
