from scipy.spatial import cKDTree as KDTree
ImportError: No module named scipy.spatial

But even after installing scypi with pip, I still get the error.

pip install scipy

--Edit--
The pip install is failing on my vagrant. Investigating.
numpy.distutils.system_info.NotFoundError: no lapack/blas resources found

In either case, it would be useful for the need for scipy to be documented in the README or included in the setup.py.
