Python - Matplotlib and Numpy on Debian/Ubuntu

There are `python-matplotlib` and `python-numpy` packages in the Debian/Ubuntu repos.

However, if you want to run in a virtualenv (with no-site-packages), and pip install these packages from PyPI, you need some system dependencies installed first to build with:

$ sudo apt-get install build-essential python-dev libfreetype6-dev libpng-dev python-virtualenv

Then, you can create a virtualenv, and the installers for Numpy and Matplotlib will work:

$ virtualenv env
$ cd env
$ source bin/activate
(env)$ pip install numpy matplotlib

Cleaning up...

(tested on Ubuntu Oneiric 11.10 and Ubuntu Precise 12.04 alpha)

Hi Corey,

I was exactly trying this yesterday but had still some problem with the backend used by matplotlib. For instance, the gtk and the Qt4 backends are not pip installable. I think I had also problem with the wxpython backend.

Would you have any experience in this regard ?

Does this also work with SciPy?

Personally I prefer sudo apt-get build-dep python-matplotlib etc.
