| Installing Opus | |
This section provides instructions for installing Opus, UrbanSim, as well as the external software required by Opus and UrbanSim.
Opus and UrbanSim are intended to be platform-independent. We have successfully installed and used the system under the Windows, Linux, and Macintosh operating systems. These installation directions have been tested with Windows XP, SuSe Linux, and Macintosh OS X Versions 10.4 and 10.5 with Intel processors, and version 10.4 with PPC processor.
Opus and UrbanSim rely on numerous other open-source systems, in particular Python, Qt, and a non-trivial set of Python packages. For Windows, we've written an installer, which takes care of downloading Python and the required packages. For Linux and Macintosh, however, there is not (yet) such a bundled set of packages, so the process of installing all the supporting software on those systems can be a bit tedious, although hopefully straightforward.
Opus and UrbanSim work with Python 2.5. In general, we recommend you use the most recent snapshot of these external applications, though if you are have problems, try using one of the versions mentioned here. These instructions assume you are using Python 2.5.1. If you are using different versions, adjust the instructions accordingly.
To help illustrate how to setup UrbanSim for use by your own agency, these installation directions sometimes refer to a fictitious Atlantis Metropolitan Planning Organization (MPO). Where you see the word “atlantis” you may safely substitute the appropriate name for your application.
The installation steps vary according to the operating system being used:
We currently have an installer available for Windows, which will be easier to use than installing all the packages by hand. Unfortunately for Linux and Mac, right now installing by hand is the only option.
Check the release notes for significant code or data changes. If you have your own Opus package or an existing baseyear database you may need to modify your code and data.
The result of an install will be a number of packages in the Python 'site-packages' directory for the supporting software, and an Opus directory tree that holds the source code, sample project data, and xml configurations for use by the GUI.
If you no longer wish to have Opus on your computer, just remove the Opus source code directory from your Python path, delete any other environment variables, and delete the Opus directory tree. (If you want to save space, you can also uninstall any supporting software that you downloaded just to use with Opus.)
