What is the easiest way to install numpy with LAPACK/BLAS?

Question

I'm on an Ubuntu 14.04.

I would have expected doing:

sudo apt-get install python-numpy

would've worked but it isn't the case...

The way I tried to check is by doing locate blas and found nothing that seemed relevant.

I would like a solution that doesn't involve me compiling from source.

The ideal solution is something that uses the ubuntu repos.

Answer 1

In Ubuntu 14.04 and later, blas and lapack are installed as part of python-scipy and python3-scipy, so you need to install python-scipy. In Ubuntu 18.04 and earlier open the terminal and type:

sudo apt install python-scipy  

This command will also install libblas3 (Basic Linear Algebra Subprograms reference implementations, shared library) and liblapack3 (Library of linear algebra routines 3 - shared version) as dependencies, and it will also install python-numpy as a dependency if you don't already have it installed.
