after a while trying to find the legal manner to file numpy bug reports, since it's a simple one, I thought maybe a first step is to describe the bug here. Then maybe someone will direct me to the right channel.
So, numpy appears not to correctly compute bitwiseand.reduce and bitwiseor.reduce : instead of reducing over the complete axis, these methods only take the extremities into account. Illustration : >>> from numpy import * >>> bitwiseor.reduce(array([8,256,32,8])) 8 >>> import numpy >>> numpy.version '0.9.8' >>> Platform : Win XP SP2, Python 2.4.2
Most bug reports start on the numpy list, I believe. (See above.)
Cheers, Alan Isaac
