Hi, yes it also works for scipy. I didn't patch the scipy source other than creating site.cfg with the path to openblas.I will upload the binaries and logs later today. Regards Carl scipy.test(verbose=2) runs without segfault: ... ==

2013-11-12 Thread Bart Baker
Hi all, First time posting. I've been working on a class for solving a group of affine models and decided to drop down to C for a portion of the code for improved performance. There are two questions that I've had come up from this. 1) I've written the section of code, which involved a series o
