[SciPy-user] OS X users - Please try multiple scipy.test() runs
Thu Sep 27 13:24:18 CDT 2007
I just reported some strange scipy crashes I've experienced on my
MacBook running OS X Tiger & Python 2.5.1. I'd like to find out
more about the conditions producing the crash. If OS X users
could do the following simple test and report the results, it
would be very helpful. Please also report details about your
platform (machine, OS version, Python, numpy & scipy versions).
All you have to do is start Python, import scipy, and run
scipy.test() *multiple times*:
>>> import scipy
and so on, up to 10 times. For me, with Python-2.5.1, numpy-126.96.36.199,
and scipy-0.6.0, right after install I get a crash at the 10th time.
Subsequent attempts (with new Python invocations) give crashes earlier
and earlier. Eventually the crash is fully reproducible at the
3rd scipy.test(), always crashing here:
Found 42 tests for scipy.lib.lapack
Found 41 tests for scipy.linalg.basic
<module 'scipy.linalg.fblas' from
I get similar crashes with scipy-0.5.2.1, but the conditions are not
On a G4 (PPC) machine running Py-2.4.4 and scipy-0.5.2.1, I don't
get any crashes (I ran scipy.test() 12 times in a row).
Your help would be appreciated in sorting out the conditions under
which such crashes happen.
PS: For the curious, I was led to this somewhat accidentally,
due to problems with linalg I'm experiencing under RHEL 5 and
another user is experiencing with FC4. I was trying to see if
the problems were platform-specific.
