• Python is often pre-installed on your system or easy to download. More difficult is to get the essential packages (numpy, scipy, matplotlib, ipython) and their dependencies installed. Here, I list some of the possibilities.

on MacOsX: using MacPorts

  • A basic installation procedure is to use the enthought distribution,

  • Another route is to use MacPorts. It is a generic package manager inspired by what you get using Debian's apt scheme.

  • Once installed, do on the command-line

    • on Leopard:

      sudo port install py25-pil py25-numpy py25-scipy py25-ipython py25-matplotlib +cairo+latex+tkinter
      sudo python_select python25

      (Note: you may also use python26 on Leopard).

    • on Snow Leopard:

      sudo port install py26-numpy py26-scipy py26-ipython py26-matplotlib
      sudo port install py26-pyobjc2-cocoa py26-pil py26-distribute py26-pip py26-py2app python_select
      sudo port install vtk5 +carbon +qt4_mac +python26 py26-mayavi
      sudo python_select python26

      to install a bunch of useful python packages.

    • to get a package that is not available through macports, do:

      sudo easy_install progressbar
  • for visionEgg :

    sudo port install py26-opengl py26-game
    sudo easy_install visionegg
  • http://ipython.scipy.org/moin/Py4Science/InstallationOSX

  • on Snow Leopard, you'll have to follow these instructions.

Debian / Ubuntu

DistUtils, PIP & Easy Install

  • most of the time, there's a setup.py file:

    python setup.py install --prefix=~
  • See http://peak.telecommunity.com/DevCenter/EasyInstall

  • to install numpy (same for pylab, scipy, or visionegg), simply do

    easy_install numpy
  • most of the cases, on a test server or a single-user machine, you may find more useful to install in your home dirtectory, for instance:

    easy_install -d ~/lib/python2.5/site-packages/ numpy
  • to upgrade, use

    easy_install -U numpy
  • you can browse the list of available packages.

  • for pip: http://pip.openplans.org/

  • you may create a script tu update all packages:

    for i in `python -c "for dist in __import__('pkg_resources').working_set: print dist.project_name"`:
    echo "`easy_install -U $i`"
    echo "++++++++++++++++++++++++++++++++++++++++++++++++++"
  • to install PIL, use

    easy_install -d lib/python2.6/site-packages/ --find-links http://www.pythonware.com/products/pil/ Imaging
