I believe that a lot can be learned from matplotlib's recent foray into appveyor. Don't hesitate to ask questions on our dev mailing list (I wasn't personally involved, so I don't know what was learned). Cheers! Ben Root On Fri, Dec 18, 2015 at 5:27 PM, Nathaniel Smith wrote: > On Dec 18, 2015

[Numpy-discussion] numpy.power -> numpy.random.choice Probabilities don't sum to 1

Hi, I have a matrix whose entries I must raise to a certain power and then normalize by row. After I do that, when I pass some rows to numpy.random.choice, I get a ValueError: probabilities do not sum to 1. I understand that floating point is not perfect, and my matrix is so large that I canno

[Numpy-discussion] Introducing outer/orthonongal indexing to numpy

Hello all, sorry for cross posting (discussion should go to the numpy list). But I would like to get a bit of discussion on the introduction of (mostly) two new ways to index numpy arrays. This would also define a way for code working with different array-likes, some of which implement outer index

[Numpy-discussion] Proposal: stop providing official win32 downloads (for now)

Hi all, I'm wondering what people think of the idea of us (= numpy) stopping providing our "official" win32 builds (the "superpack installers" distributed on sourceforge) starting with the next release. These builds are: - low quality: they're linked to an old & untuned build of ATLAS, so linear
