What is the easiest way to install BLAS and LAPACK for scipy?

Question

I would like to run a programme that someone else has prepared and it includes scipy. I have tried to install scipy with

pip install scipy

Answer 1

Always for Ubuntu/Debian, chjortlund's answer it's very good but not perfect, since this way you get an unoptimized BLAS library. You have simply to do:

sudo apt install libatlas-base-dev

and voila'!
