numarray 1.4.1: Infinite loop during test
import numarray.testall as testall testall.test() Testing numarray 1.4.1 on normal Python (2, 4, 2, 'final', 0) on
I have a PC with Debian unstable. I use Python 1.4.2. After installing numarray 1.4.1, I ran the tests: platform linux2 numarray.numtest: 2.89 ((0, 1205), (0, 1205)) numarray.ieeespecial: 0.07 (0, 86) numarray.records: 0.05 (0, 48) numarray.strings: 0.17 (0, 189) numarray.memmap: 0.09 (0, 82) numarray.objects: 0.14 (0, 105) numarray.memorytest: 0.01 (0, 16) numarray.examples.convolve: 0.09 ((0, 20), (0, 20), (0, 20), (0, 20)) numarray.convolve: 0.06 (0, 45) numarray.fft: 0.11 (0, 75) After the above, nothing happens. "ps ax" show a lot of time being used. Looks like an infinite loop. Process had to be killed.

I don't have access to a Debian system but some things come to mind: a. The loop looks like it's in numarray.linear_algebra. b. I changed numarray's setup to make the "config" command automatic for 1.4.0. That changes how the builtin lapack_lite module is configured/built which affects linear_algebra. c. My impression is that debian builds numarray against external libraries so (b) shouldn't be the problem. Does the numarray tarball from source forge: http://prdownloads.sourceforge.net/numpy/numarray-1.4.1.tar.gz?download install and self-test OK using "python setup.py install"? Regards, Todd
