The default axis was changed recently to None (btw, which version are you using?), see the release notes on the web. So yes, it's expected. > > 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...) on my 1.0b5 I also see this docstring which indeed seems obsolete. Has it been changed since then? (And similarly for the other functions/methods where axis arguments have changed.) I could check the docstrings systematically and update them, but unfortunately not before the end of this month, sorry. cheers, sven ------------------------------------------------------------------------- Using Tomcat but need to do more?
