Strange behaviour - Normalised Cut (on Macbook)

[bricklemacho at gmail.com]

The versions are the same on both machines.

numpy 1.9.2
scipy 0.15.1
arpack - not sure how to find the version, scipy.linalg.__version__ is 0.4.9

On my work machine, I had been mucking around earlier on a local branch 
of skimage, working on future.graph. As mention below I removed 
everything from site-packages, I don't think there is anything else 
lying around.


Regards,

Michael.
