The problem is that the sum axis default is None, not 0. > Is that the expected behaviour or is the doc not updated? (I realise it > may be better to force axis=.. to indicate what you need but still.. the > example in numpy.sum help gives: > sum([[0, 1], [0, 5]]) > array([0, 6]) which is not what it gives when you do it...) The documentation seems to be outdated. I'm not sure, but I think a few of the axis default might have changed in the not too distant past. Not sure if sum was affected. Either way, could you please file a ticket? http://projects.scipy.org/scipy/numpy/register http://projects.scipy.org/scipy/numpy/newticket Regards, Albert ------------------------------------------------------------------------- Using Tomcat but need to do more?
