[Numpy-discussion] problem with lapack_lite / BLAS
Dear list, I'm trying to compile ATLAS 3.6.0 and LAPACK 3.0 (+ update) and use them with the latest numpy (checked out today). Installation seems to be fine, all the libraries are detected. When I import numpy, however, I get this: Python 2.5 (r25:51908, Sep 27 2006, 17:40:29) [GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2 Type help, copyright, credits or license for more information. import numpy Traceback (most recent call last): File stdin, line 1, in module File /home/langner/apps/python/lib/python2.5/site-packages/numpy/__init__.py, line 40, in module import linalg File /home/langner/apps/python/lib/python2.5/site-packages/numpy/linalg/__init__.py, line 4, in module from linalg import * File /home/langner/apps/python/lib/python2.5/site-packages/numpy/linalg/linalg.py, line 25, in module from numpy.linalg import lapack_lite ImportError: /home/langner/apps/python/lib/python2.5/site-packages/numpy/linalg/lapack_lite.so: undefined symbol: xerbla_ Does anyone know where this comes from?

[Numpy-discussion] Numpy types and object comparison
Hi, I am sorry, I am still struggling with object arrays - and here - numpy data types. Is there any easy way to explain why comparisons with numpy types give a different output from comparisons with non-numpy types: In [108]:oa = zeros((1,), dtype=object) In [109]:oa == int Out[109]:array([False], dtype=bool) In [110]:oa == int32 Out[110]:False Many thanks for your patience, Matthew - Take Surveys.

[Numpy-discussion] paypal won't take my money for scipy docs
I fill in the credit-card form, press continue, and it comes back with Some required information is missing; the indicated missing info is the 'security code' you copy in to prove you are human, which I had entered. This happened 3 times in a row, and I am certain I got it right at least the last two (I even listened to the audio read-out the third time). So I am starting to get concerned that something is being intercepted.. I'm guessing that a paypal merchant is more likely to get attention from paypal than an accountless purchaser - any idea what's going on here? - Take Surveys. Earn Cash.

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.
