yes thats probably openblas fault. Openblas crashes all the time as soon as your matrices get bigger than a couple of megabytes. I'll investigate and report it upstream (as I have already far too often for the exact same reason ...) On Wed, Oct 9, 2013 at 5:05 PM, Charanpal Dhanjal wrote: > Oops

[Numpy-discussion] Segfault with QR Decomposition

2013-10-09 Thread Charanpal Dhanjal
I get a segmentation fault upon running the following: import numpy A = numpy.ones((700, 8)) Q, R = numpy.linalg.qr(A) on Python 2.7.3, Linux 64-bit using numpy 1.9.0.dev-ec3603f linked against OpenBLAS. If A is a smaller matrix then the QR decomposition works (for example A has shape (40
