Dear all,
Sorry if that's a noob question, but anyway. I have several thousands of
vectors stacked in 2d array. I'd like to get new array containing
Euclidean norms of these vectors and get the vector with minimal norm.
Is there more efficient way to do this than
argmin(array([sqrt(dot(x,x))

argmin(add.reduce((a*a),axis=1))

Thanks Josef, that worked!
I was confused because I was thinking of site.cfg as some sort of bash

Dear Numpy/Scipy users,
I just installed numpy but I have an error when importing
import numpy
from numpy.linalg import lapack_lite
ImportError: libatlas.so: cannot open shared object file: No such file or

I have ATLAS libraries under /usr/local/atlas/lib
libatlas.a
It looks like atlas wasn't linked right. If you /usr/local/atlas/lib
to your LIBRARY_PATH environment variable it should work.

There is a limit to how far we can actually satisfy this requirement.

Hi eat and Gary,
Thanks a lot for your suggestions, I've tried them in my code and
achieved similar speedup of ~270% for both of them. So I guess I'll
stick to one of those.
Regards,
Andrey.

Dear all,
Hello,
I really like the split() family of functions, but I have the need to split
multiple arrays in a similar manner, and it would seem logical to me to have
a split() function that would return a list of slice tuples that I could use
on multiple arrays. Is there such a function?
Thanks,
Ben
