I hope you mean just passing compiler options optionally; you don't

Hey,
Good look with the building issues. A safe solution would be to do
conditional compilation. Scipy does it
My implementation is assuming all data fits in memory. I'll do some
benchmarks and look into the openmp/building/cython issues.

This is very true, w

The reason that we have integrated openmp code in the scikit so far, is that it
does not seem that there is a reliable way of testing if a compiler supports it
with distutils. The danger is thus to break the build for certain evironments.

It may be relevant to note that Cython has recently gained some OpenMP
support: http://docs.cython.org/src/userguide/parallelism.html -- I
haven't tried it, but perhaps it could help improve the scikit-learn
implementation.

Hi,
I was wondering about the KMeans implementation in scikit-learn. From a
quick scan of the code I see that the main stuff is implemented in
Cython but it's spread in two different functions for the m- and the
e-step and the main loop is in python. I'm using my own KMeans routine
written as a Py
