GWR: RuntimeWarning: divide by zero encountered in divide

[Algunenano]

When running the python tests I'm getting this runtime warning:

nosetests2 crankshaft/test/
/usr/lib/python2.7/site-packages/sklearn/cross_validation.py:41: DeprecationWarning: This module was deprecated in version 0.18 in favor of the model_selection module into which all the refactored classes and functions are moved. Also note that the interface of the new CV iterators are different from that of this module. This module will be removed in 0.20.
