EPD Python on Ubuntu

Enthought Python Distribution or EPD as it is popularly known as is a Python distribution with lot of libraries already available in it. Whats good about it? The libraries are in their latests version available (or may be one or two versions lower). Ubuntu repositories also have these libraries so one can install them from there. But, the problem with Ubuntu repositories is that they contain pretty old versions of the library. For example the current version of Networkx available in Natty repositories is 1.1 while that current stable version of Networkx is 1.5.

EPD is installed using the shell script installer enthought provides. I have installed it in the home directory. So by typing ‘python’ in terminal I do not have access to EPD python. What I did is the following – I made a link named it ‘pythoEPD’ and copies the link to ‘/usr/bin’. This way I will be able to access EPD python from anywhere on terminal by typing ‘pythonEPD’.

Although EPD has a good collection of libraries it might not have all that you need. I have not been very successful in installing downloaded libraries to the EPD library list. So it will be good to install them from ubuntu repositories using the awesome ‘apt-get’ command. But, these will not be available to EPD python. To make them available to the EPD python distribution one needs to add the standard python path to the EPD python path. To do that open terminal.

  1. Run python by typing – python.
  2. import sys; sys.path
  3. The above command will show you the standard python path. copy the entire list to clipboard.
  4. Open another terminal run – pythonEPD (to run EPD python).
  5. paste the list to a variable, say x.
  6. iterate over its entries and append it to the EPD python path.
