No module named scipy.stats - Why, even though scipy is installed

Question

How to use python and scipy to get a random poissio variable? Wow .. I installed scipy, and for the documents I received, there is no module called scipy.stats? I'm on ubuntu 12.04. So ... go figure

Answer 1

I think scipy is the way to go. You probably have a simple namespace visibility issue. since statistics itself is a module that you need to import first, then you can use functions from scipy.stats

import scipy
import scipy.stats
#now you can use
scipy.stats.poisson
#if you want it more accessible you could do what you did above
from scipy.stats import poisson
#then call poisson directly
poisson

Answer 4

I had a similar problem with Python 3.4 on my windows 7 machine. I had to upgrade my scipy package 'pip install --upgrade scipy'
