Infrastructure designed to enhance the usability of innovative spatial econometric methods within the Python Spatial Analysis Library (PySAL). The integration framework leverages the user interface and data management capabilities provided in ArcGIS making analytical techniques developed in PySAL more accessible to the general GIS User.

For the majority of Users, the ArcGIS Installation Process will have already installed the correct version of Python and the supporting packages and therefore can skip to the next Step.

For those that used the advanced installation option to allow you to install Python yourself it is up to you to make sure the packages conform. The easiest way to do this is to just install the correct Python Package Versions related to your own ArcGIS install:

Note that in the PyParsing Python Package is no longer installed with this version of Matplotlib 1.3.0, however, it is required in order for Matplotlib to function properly. It is advised that you install PyParsing 1.5.7 if you are managing your own Python Installation.

This project requires the SciPy Python Package, however, confusion/problems may arise due to the emergence of the SciPy Stack. The latter package contains an all-in-one suite of packages to support analytics in Python, yet it often includes a version of NumPy or MatPlotLib that does not conform with the ArcGIS release. It is advised that you install SciPy by itself and avoid the SciPy Stack unless you are willing to fix any issues that may arise.

We are not aware of any constraints concerning the version of SciPy and how it relates to the Python Packages listed in Step 1. We suggest that you obtain version 0.13.0 from the SourceForge Download Site:

Download SciPy

1. Clone the latest PySAL repository: PySAL GitHub Site.
   Please note the directory you cloned it to: E.g. C:\Data\git.
2. Append the base PySAL directory (in above example: C:\Data\git\pysal) to your Python Path using the desktop10.x.pth file that the ArcGIS Installation Process created. The file is located in your $PYTHONHOME\Lib\site-packages directory (Most common location is C:\Python27\Desktop10.x\Lib\site-packages).

1. Clone the latest PySAL-ArcGIS-Toolbox repository: PySAL-ArcGIS-Toolbox GitHub Site.
2. If you are only going to use the Toolbox and supporting scripts as ArcGIS Script Tools then you do not need to continue with the steps below. However, if you want to be able to call the functions provided by this project from within the Python Window or Terminal then you must add the PySAL-ArcGIS-Toolbox\Scripts directory to your Python Path the same way you did this for PySAL in Step 3 (GitHub Version).
3. Append the base PySAL-ArcGIS-Toolbox directory (E.g. C:\Data\git\PySAL-ArcGIS-Toolbox) to your Python Path using the desktop10.x.pth file that the ArcGIS Installation Process created. Again, the most common location is C:\Python27\Desktop10.x\Lib\site-packages).
