skl-groups-accel 0.1.1

Compiled components to speed up skl-groups.

This package contains Cython extensions for the skl-groups package. Its purpose is to make skl-groups proper easier to install by not requiring a compiler or having FLANN installed / etc.

It currently contains only a (much) faster implementation of the core portion of skl_groups.divergences.knn.KNNDivergenceEstimator.

Installation

This code is written and tested for Python 2.7, 3.3, and 3.4. 3.2 probably works. It is also only tested on OS X and Linux, though it’s not known not to work on other platforms; let me know if you try it.

The easy way to install is:

$ conda install -c http://conda.binstar.org/dougal skl-groups

if you use conda, which includes both skl-groups and skl-groups-accel.

Otherwise, first install skl-groups and cyflann. You’ll also need a compiler with OpenMP support, so gcc (not llvm-gcc) instead of clang (for now). On OSX, do brew install gcc and then set CC=gcc-4.8; Linux users probably have gcc installed, but make sure to set CC if you default to clang. Then you can:

$ pip install skl-groups-accel

or, from a source checkout, python setup.py install or pip install . or whatever. If you’re installing from a source checkout you need a recent version of Cython.
