Import numpy with python 2.6
You shouldn't have to add those things to the path. Python knows where to look for installed modules as long as you have C:\Python26 in the path.
Sven Marnach was asking if you did it like this:
import numpy as npx=np.array([[7,8,5],[3,5,7]],np.int32)
Edit: I just noticed you left out a comma in your array declaration also...fixed it in the above
