IMO the Modular toolkit for Data Processing (MDP) has a fairly good and straightforward PCA implementation, among other good tools: mdp-toolkit.sourceforge.net/

I have no idea what apt-get is, though, so I don't know if this will be helpful or not!

Apt-get fetches and installs packages for Debian and Debian based Linux distributions like Ubuntu.

Except last I checked numpy.linalg doesn't have an efficient method for retrieving only a few PCA components. So yeh, you can do PCA but it will be *really* slow on most of the types of problems that PCA is usually used for. You need something like an ARPACK wrapper, which I think they have in the scipy.sandbox.

Hi,

You have everything you need for PCA in numpy.linalg.

I'm doing some projects in Python (system GNU / Linux - Ubuntu 7.0) about image processing. I'm needing a implementation of PCA, prefer to library for apt-get.

Thanks. Alex.
