python/numpy on RHEL6.1

netnix99 · 07-06-2011, 09:47 AM

Installed python and numpy on clean install of RHEL 6.1. When I run the numpy test script, this is the output:

[root@computer tmp]# python -c 'import numpy ; numpy.test()'
Running unit tests for numpy
NumPy version 1.3.0
NumPy is installed in /usr/lib/python2.6/site-packages/numpy
Python version 2.6.6 (r266:84292, Apr 11 2011, 15:52:27) [GCC 4.4.4 20100726 (Red Hat 4.4.4-13)]
nose version 0.10.4
..........Illegal instruction (core dumped)

I have a support ticket in with RH on this as well.

Thanks for the help!

Those programs are all installed...the test fails whether I am root or a regular user, I just happened to be root when I made the post, so I ran the test script to get the text of the output error for this post.

Sorry, for no usable solution.

I did this now : Updated to python 2.6.6-20.el6
Test result : Ran 2021 tests in 15.984s OK (KNOWNFAIL=1)

And then I removed 'python-devel' ( Not required for numpy.)
A new test : Ran 2021 tests in 17.406s OK (KNOWNFAIL=1)

Things to consider : Is one of the 32bits packages corrupt ?
( As you can see, I am using a 64bits OS (= SL6, Scientific Linux.))
I may give the 32bit OS a try tomorrow.

I have the updated version of python installed (2.6.6-20.el6) and the same version of numpy as well. Oddly enough, it works on two machines, but fails on 3 other machines...all loaded the exact same way. I even tried to clone one of the working machines, and that failed as well. I just tested it on my 64-bit machine... Ran 2021 tests in 11.548s OK (KNOWNFAIL=1) Red Hat says they have it working on 32 and 64 bit machines...I sent them some additional info and they are trying to recreate the issue...

I really appreciate the effort!

Cheers,
