Please post this to numpy-discussion instead of here. Also, please create a ticket in our Trac: http://projects.scipy.org/scipy/numpy > The problem appears to come > from changing values in the array.

It's possible that there is a bug with the scalar objects that are being created when indexing into the arrays. I can reproduce abnormal memory consumption even when I remove the line where you are setting value in the if: clause. > Also, are there other python methods/extensions that can create > multi-deminsional > arrays? A few. numpy's predecessors, Numeric and numarray are still usable, but aren't being actively developed. There's a pure-Python array package somewhere, but I forget the name. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
