hi there.

I'm struggling with a function of numpy. Here it is :

import numpy as NP

mean = NP.array([0,0])

cov = NP.array([[1,0.25],[0.25,1]])

v = NP.random.multivariate_normal(mean,cov)

Quite simple code : it is supposed to generate an array of two random

values taken from a multinormal distribution, with respect to means and

covariance matrix given as parameters.

What happens on my computer is simple : it freezes ! I can't even stop

the process with ctrl-C in my python interpreter i have to kill it from

outside.

I'm running :

- python 2.4.1

- numpy 0.9.8

Well, it's working quite well for me on OS X PPC and Linux AMD-64 with a

reasonably recent SVN checkout of numpy. Did you build numpy yourself, or use a

binary distribution? Windows? Linux? OS X?

Please join us on the numpy mailing list with this information; hopefully there

is someone there with a similar platform who can replicate your bug or offer

better advice than myself.

In the meantime, you might try compiling a recent SVN checkout of numpy and see

if the problem goes away for you.
