Answer 1

You can either add scipy.sparse.csgraph._validation to the includes option in your setup.py script

setup( 
    ...
    options = { 'includes': ['scipy.sparse.csgraph._validation'] }
)

or just force py2exe to spot it by forcing an import - somewhere in your code put

import scipy.sparse.csgraph._validation
