Re: [Numpy-discussion] OverflowError: long too big to convert

OK...so just for future reference...does a Numpy 'long' not directly correspond to a Python 'long'? Robert Kern wrote:

Can someone explain this? I can't seem to coerce numpy into storing large integer values. I'm sure that I'm just overlooking something simple...

Use object arrays explicitly:

c = numpy.empty((2, 2), dtype=object)

Using dtype=long gets interpreted as requesting the largest available integer type (or maybe just int64, I'm not sure). Those aren't unbounded.
