The first thing is to verify that sys.executable is the same in your 
command shell and Wing's Python Shell.  If it is not, set the Python 
Executable in Project Properties to the sys.executable in the shell 
where it works.  It looks like you're running a build of Python that 
does not match the build parameters for the extension module in 

If that does not help, you may also want to see if numpy.core.multiarray 
within and outside of Wing are coming from the same file. If not, check 
the sys.path and look at modifying Python Path in your Project 
Properties as well.

If none of that helps, please let us know which version of Wing you are 
using and how you obtained or compiled Python and numpy.
