Hi everybody,

I'm using Python 2.1.1 and Numpy 20.1.0 This seems to be a problem:

Python 2.1.1 (#2, Jul 31 2001, 14:10:42) [GCC 2.96 20000731 (Linux-Mandrake 8.0 2.96-0.48mdk)] on linux2 Type "copyright", "credits" or "license" for more information.

...

...

from Numeric import * from MLab import zeros joe = zeros(3,'l',1) fred = array([1,2,3],'l') joe += fred

Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: return array has incorrect type

This fails whether or not fred has the spacesaver flag set.

This, however, works fine:

...

...

...

joe = zeros(3, 'l') fred = array([1,2,3], 'l') joe += fred joe

array([1, 2, 3])

Am I doing something wrong or is this a bug?

Thanks for the bug report, Nathan. It was indeed a bug, which I hope has now been squashed in the latest CVS version of Numeric. Thanks for your help. Travis
