[Numpy-discussion] How to tell whether I am using 32 bitor 64bit numpy?

1) 32-bit Numpy/Scipy with 32-bit Python on 64-bit Windows does work. But, it doesn't take advantage of memory > 2gb.
2) Happy to help out with the experimental 64-bit builds of Numpy/Scipy. But, would this be with pre-installed Windows libraries or source files as I'm not setup for dealing with source files? The machine has an Intel Core2 Quad CPU with 8gb ram. Strangely, the 64-bit Python 2.5x Intel version wouldn't install but the AMD version did.

That's a totally different situation: in your case, python and numpy
share the same address space in one process (for all purpose, numpy is a
dll for python), and you certainly can't mix 32 and 64 bits in the same
process. What you can do is running 32 bits numpy/scipy for a 32 bits
python on windows 64 bits...
... or helping us making numpy and scipy work on windows 64 bits by
testing the experimental 64 bits builds of numpy/scipy for windows :)
cheers,
David
