[SciPy-user] Accessing modules in packages

[Dave Bazell]

I am trying to use scipy.cluster.vq.kmeans.  I have imported scipy:

> import scipy

and tried cluster.vq.kmeans(..) but I get an error "no module vq in cluster"
or something like that.

I have tried

from scipy import *
from scipy.cluster import *

and

from scipy.cluster.vq import *

but none of these allow me to access cluster.vq.kmeans.

If I copy the vq.py file to my working directory and do

import vq

then I can access it.

What am I doing wrong?  I am sure this is a simple thing to answer and
displays my current (but decreasing) ignorance of python.

Thanks,
