OK... I am so angry at myself... I spent around 2 hours fiddling around with blas/lapack and numpy, and the problem was that I wasn't removing the 'build' directory between compiilations. Apparently it's not enough to run "setup.py clean" (I read this and forgot about it) to recompile lapack_lite.so. Now numpy imports fine and everything I use it for works as before (only a bit faster). Karol P.S. I still get a floating point exception when running the numpy tests, though. I haven't checked out numpy for some time, so I don't now if it's a bug, or if it's my setup. The same thing happens when I use my manually built atlas/lapack and the built-in debian atlas/lapack libraries. I'd be grateful for a comment on if this is just me: >>numpy.test(10,10) [output] Check reading the top fields of a nested array ... ok Check reading the nested fields of a nested array (1st level) ... ok Check access nested descriptors of a nested array (1st level) ... ok Check reading the nested fields of a nested array (2nd level) ... ok Check access nested descriptors of a nested array (2nd level) ... ok check_access_fields (numpy.core.tests.test_numerictypes.test_read_values_plain_multiple) ... ok check_access_fields (numpy.core.tests.test_numerictypes.test_read_values_plain_single) ... ok check_cdouble (numpy.tests.test_linalg.test_det)Floating point exception thanks! -- written by Karol Langner Sat Oct 7 19:41:58 CEST 2006 ------------------------------------------------------------------------- Take Surveys.
