Hi all, I'm wondering if this is a bug...
Something strange happens with my ufunc as soon as I use 1 elements. As
the test shows, the ufunc computes the correct result for either the first
or last elements, but both at the same time is no good.
Turns out I'm only running numpy 1.3.0 with

This consistently gives me a "MemoryError".
I believe I have plenty of physical memory.
(That should require about 1.3G during creation, right?
I have 8G.) It seems I'm hitting some kind of 1G

Hi all,
I have a possibly naive question. I don't really understand this
particular set of output:
In [1]: import numpy
In [2]: a1 = numpy.random.random((512,512,512)).astype("float32")
In [3]: a1.sum(axis=0).sum(axis=0).sum(axis=0)
Out[3]: 67110312.0
In [4]: a1.sum()
Out[4]: 16777216.0

Hello,
I am trying to use f2py to generate a wrapped C function that I can
call from Python (passing arguments to and from). I have this almost
working, but I receive trouble with "exp and pow" related to C and
some "pos (2) error" with one of my passed variables. My f2py syntax
is:
f2py -c -lm F

Hi,
I tried upgrading today and had trouble building numpy (after rm -rf
build). My full build log is here:

If someone can point me in the right direction, I'd appreciate it very
much. To excerpts from the log file:
