Installation procedure for numpy and other python-3.4 packages on ubuntu 14.04

From the terminal run:

sudo apt-get install python3-numpy

This package contains Numpy for Python 3. And as you might expect, there is also a package in the Ubuntu Software Center for Ubuntu 14.04 called python3-scipy. If you have python3-numpy and python3-scipy installed and you want to use pylab for plotting graphs, then you'll also need to install python3-matplotlib.

I first installed pip for python 3.

sudo apt-get install python3-pip

And then installed numpy with pip3.

sudo pip3 install numpy

This could run too,

sudo apt-get -y install python-numpy
