Just to be sure, you CAN'T expect sum to always have the same result in float{32,64,128}. This is a properties of float numbers, but if you add precission, you can hide this problem in some/most case. Fred On Sun, Aug 25, 2013 at 4:30 PM, Matthieu Brucher < matthieu.bruc...@gmail.com> wrote: >

Hi, I'm looking at the build of scikit-learn for guidance on some statsmodels improvements, and I'm wondering about this in the setup.py. What could this do? from numpy.distutils.system_info import get_info blas_info = get_info('blas_opt', 0) blas_info.get('define_macros') My numpy is linked aga

Dave, Have you looked at the source of the GMM estimator in scikit-learn? It's a pretty concisely implemented EM algorithm: https://github.com/scikit-learn/scikit-learn/blob/master/sklearn/mixture/gmm.py#L451 Jake On Tue, Sep 3, 2013 at 7:36 AM, David Reed wrote: > Hi there, > > Does anyone

I do not know what the problem is because I cannot even reproduce it. I will fix it as soon as I can figure it out. In the meantime, I've submitted this pull request to skip the test, so builds do not fail: [1]https://github.com/scikit-learn/scikit-learn/pull/2415 On Mon, Sep 2, 2013, at 08
