2.1 Overview of installation

Before we can begin the tutorial, you need install and test Python, NumPy and some other Python extensions, and PyPedal itself. PyPedal has been tested against the versions listed in Table 2.1, and may not work with earlier releases of those packages. The extensions that you need to install in order to use all of the features of PyPedal are listed in Table 2.1. Note that some extensions need to be installed before others: Numpy should be installed first, and pyparsing and Graphviz must be installed before pydot.

If you do not install one or more optional modules you will still be able to use PyPedal, although some features may not be available to you. Details on installing the extensions listed above can be found on their respective websites. All of these extensions are available for Unix-type operating systems (e.g. Linux, Mac OS X) as well as for Microsoft Windows; most sites also provide binary installers for Windows. Python extensions can usually be installed by unzipping/untaring the archives, entering the folder, and issuing the command "python setup.py install" as a root/administrative user. Note that NetworkX and ReportLab are not installed by the Enthought Python Distribution for Windows. I have found that installations from source on Linux are sometimes tricky, but I have found that Sage (http://www.sagemath.org/index.html) does a great job of getting clean builds of the trickier pieces, such as Numpy and matplotlib.

The PyPedal distribution includes a copy of the ADOdb for Python (http://http://phplens.com/lens/adodb/adodb-py-docs.htm/) database abstraction library. It is installed with PyPedal and does not require a separate installation step.
