When I run the tests I get 16 failures mostly nan related. I have no idea
whether they are real or if there is still something screwed up in my
setup. See below.
I can reproduce those. I did

Oh, thanks! No, I forgot to report it on trac, I'll try to remember
that in the future.

Hi,
I have started again, simply executing:
python setup.py install
However, I now get the following:
File numpy/core/setup.py, line 253, in check_mathlib
raise EnvironmentError(math library missing; rerun
EnvironmentError: math library missing; rerun setup.py after setting the

The title of this e-mail is probably misleading so let me just show some code:
from numpy import *
A=array([[1,2],[2,3],[3,4]])
B=array([[2,2],[3,3]])
C=zeros(A.shape)
for i in xrange(len(A)):
C[i]=sum(A[i]**B)
print C
What I want to do is eliminate the for loop and rely on numpy
internals,
ugh... I goofed. The code snippet should have read
from numpy import *
A=array([[1,2],[2,3],[3,4]])
B=array([[2,2],[3,3]])
C=zeros(A.shape)
for i in xrange(len(A)):
C[i]=(A[i]**B).sum(0)

Hello Damien,
broadcasting can solve your problem (see
http://docs.scipy.org/doc/numpy/user/basics.broadcasting.html):
(A[np.newaxis,:]**B[:,np.newaxis]).sum(axis=0)
gives the result you want.
(assuming import numpy as np, which is considered as a better practice
as from numpy import *)
Emanuelle,
perfect! thanks.
(assuming import numpy as np, which is considered as a better practice

actually I normally just import numpy but I guess np is nicer to
type and read...
cheers,

Hi all,
Whenever I run numpy.linalg.lstsq with a xs parameter with both
dimensions larger than 128, I get an Illegal instruction and python
dies completely. It happens with both the Ubuntu jaunty standard numpy
1.2.1, and a recent svn 1.4.0.dev7727, but it doesn't seem to happen
on any other

I have a line of matplotlib code
-self.ax.plot(plot_data,mif)

This is on a windows xp machine with latest numpy and the latest matplotlib.

also, the exception is only thrown when I plot something first. I wonder if
matplotlib is messing something up.

If there is a memory error, no
I turns out I *was* running out of memory. My dimensions would require 3.5
gig and my plot must have used up some memory.

With a modern filesystem, usually you are only limited to the amount
of contiguous free space in your process's current address space.

It depends not just on what your CPU is capable of, but also your OS
and how your Python was built. If all three of those are 64-bit
capable, you should be able to
