Hi everybody,
I am trying to install python2.5/scipy/numpy/sympy/matplotlib locally,
because of various reasons. I am not root.
At home I am using Ubuntu and I am root and everything works as it should.
So far I managed to make python2.5, sympy and ipython to run fine on
my computer at work, but

Hi everyone
I have a quick problem. I'm trying to write a routine to "demosaic" video data
extremely quickly. I thought my algorithm would make good use of my
processor's vector math units, but it isn't fast enough (it currently takes
about 300ms for each 8 megapixel frame) Maybe you can hel

I'd like to add a way for loadtxt to infer a dtype from the data it

Thanks very much everyone, this has been very helpful. I have been doing
some timing of my own and the order of magnitude difference that numpy
provides wins. I'm learning python as I go so some of my questions come
from a lack of language skillls, but it is good to get to know the numpy

Hey,
I would like to release 1.2.0 final soon, but I need to know whether
anyone is having any problems with the rc2 binaries. Please test them
and let me know whether or not you have any problems with them.
Thanks,

Hi there!
Consider this python program (saved as locale_trouble.py):

everything is fine, if you call this program as follows:

Modules are cached, so the cost of importing a module, when it has
already been loaded, is simply the cost of checking if it has been
loaded, and
