Re: [Numpy-discussion] Strange crash in numpy.linalg.lstsq.

Right... So I was able to get everything working finally. I am not 100% sure how or why it works though so I am going to outline what I did here for reference. I first tried just using LAPACK 3.1.1 (since it seemed set up for g77 instead of gfortran which I do not have). I compiled this to yield

It seems to automatically detect it though. Specifically lapack_lite.so always seems to reference libatlas. On Mon, Aug 17, 2009 at 5:21 PM, Keith Goodman wrote: > On Mon, Aug 17, 2009 at 2:13 PM, Jonathan > Taylor wrote: >> Is there some alternative to get a working numpy going?  How might I >>

Re: [Numpy-discussion] Strange crash in numpy.linalg.lstsq.

Yes... ATLAS type problems like matrix multiplication. Is there some alternative to get a working numpy going? How might I go about compiling numpy without ATLAS? I really got to get at least something working temporarily. Thanks, Jon. On Mon, Aug 17, 2009 at 5:03 PM, Keith Goodman wrote: > On

I compiled lapack and atlas from scratch using g77 but now numpy.test() hangs when I try to use any numpy functionality. I think I saw someone else write about this. Is this a common problem? Thanks, Jonathan. On Mon, Aug 17, 2009 at 4:38 PM, Charles R Harris wrote: > > > On Mon, Aug 17, 2009 a

Re: [Numpy-discussion] Strange crash in numpy.linalg.lstsq.

Hi, I am using a computer that is administered. It is an intel Ubuntu box and came with an ATLAS compiled. I thus compiled my own numpy1.3.0 against that ATLAS. I was thinking about recompiling ATLAS myself. This machine only has g77 and not gfortran on it. Will that still work? Thanks, Jona

Hi, I am getting a strange crash in numpy.linalg.lstsq. I have put the code that causes the crash along with two data files on my website at: http://www.cs.toronto.edu/~jtaylor/crash/ I would be interested to know if this bug can be duplicated and/or if anyone has any suggestions as to why: im
