I recently got into trouble with these calculations (although I used scipy). I
actually got segfaults and "bus errors". The solution for me was to not link
against ATLAS, but rather link against Apple's blas/lapack libraries. That got
everything working again. I would suggest trying to install a
I posted a similar question about the non-convergence of
numpy.linalg.svd a few weeks ago. I'm not sure I can help but I wonder
if you compiled numpy with ATLAS/MKL support (try numpy.show_config())
and whether it made a difference? Also what is the condition number and
Frobenius norm of the ma
I'm bumping into the old "Eigenvalues did not converge" error using
numpy.linalg.eigh() on several different linux builds of numpy (1.4.1). The
matrix is 166x166. I can compute the eigenvalues on a Macintosh build of
numpy, and I can confirm that there aren't degenerate eigenvalues, and that
the ma
