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

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
