Is it not possible to update your versions to see if that solves the problem? DG On Wed, Jun 23, 2010 at 11:25 AM, Salim, Fadhley (CA-CIB) < fadhley.sa...@ca-cib.com> wrote: > I've been investigating a truly bizarre bug related to the use of > numpy.linalg.eig. > > I have two classes which both

2010-06-23 Thread Salim, Fadhley (CA-CIB)
I've been investigating a truly bizarre bug related to the use of numpy.linalg.eig. I have two classes which both use numpy.linalg.eig. These classes are used at very different times and are not connected in any way other than the fact that they both share this particular dependancy. I have foun

[Numpy-discussion] numpy.linalg.eig memory issue with libatlas?

2009-10-07 Thread Johan Grönqvist
[I am resending this as the previous attempt seems to have failed] Hello List, I am looking at memory errors when using numpy.linalg.eig(). Short version: I had memory errors in numpy.linalg.eig(), and I have reasons (valgrind) to believe these are due to writing to incorrect memory addresses i

[Numpy-discussion] numpy.linalg.eig

2008-09-15 Thread Tommy Carstensen
To the numpy mailing list, Previously I used python2.3 and the module LinearAlgebra for matrix diagonalization. I recently upgraded to python2.5 and I am now using numpy.linalg.eig for matrix diagonalization. This is approximately 3 times slower than previously. I am using the same work station as
