Re: [UrbanSim-Users] Latest Stable Release - Enthought 2.4.3

Hi Zak,

I spent a bit of time trying to check this out and was not able to
reproduce the error below. Here's what I did:

I got the latest Python Enthought edition for Windows from

http://www.enthought.com/products/epddownload.php

(this is for Python 2.5.2)

Then I downloaded the latest stable release of Opus/UrbanSim from

https://trondheim.cs.washington.edu/svn/opus/tags/4.1.2/

Running run_simulation_on_baseyear_cache.py in eugene/tools worked fine.

A couple of things to check:

- please make sure you are running the latest Opus stable release
(4.1.2), and not an older stable release. In January we put out a new
stable release 4.1.2 that should work with both the older Python
Enthought Edition 2.4.3 and the new ones -- the older stable releases
(e.g. 4.1.1) only work with the older Python Enthought edition.
(See http://trondheim.cs.washington.edu/cgi-bin/trac.cgi/wiki/ReleaseNotes)

- try starting up Python and make sure you can load the Enthought
packages:

from enthought.traits.ui.api import *

(this only works with the new version of Enthought)

Hope this helps ....
