Installing the released version

PySAL is available on the Python Package Index. Therefore, you can either install directly with pip from the command line:

pip install -U pysal

or download the source distribution (.tar.gz) and decompress it to your selected destination. Open a command shell and navigate to the decompressed folder. Type:

pip install .

Installing development version

Potentially, you might want to use the newest features in the development version of PySAL on github - pysal/pysal while have not been incorporated in the Pypi released version. You can achieve that by installing pysal/pysal by running the following from a command shell:

pip install git+

You can also fork the pysal/pysal repo and create a local clone of your fork. By making changes to your local clone and submitting a pull request to pysal/PySAL, you can contribute to the PySAL development.
