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 bitwise_and.reduce and bitwise_or.reduce : instead of reducing over the complete axis, these methods only take the extremities into account. Illustration : >>> from numpy import * >>> bitwise_or.reduce(array([8,256,32,8])) 8 >>> import numpy >>> numpy.__version__ '0.9.8' >>> Platform : Win XP SP2, Python 2.4.2 HTH, bb -- http://mail.python.org/mailman/listinfo/python-list
