The purpose of this code is benchmarking scipy.spatial.cKDTree for PR4890 with comparisons against SciPy 0.15.x and 0.16.x. To build: $ python setup.py build_ext --inplace or $ python setup.py build_ext $ python setup.py install Requires: Python 3.4 or 2.7 Cython NumPy SciPy C++ compiler Only tested on Python 3.4. Should run on 2.7 as well.
