Installing from Source

You can install from source by downloading a source archive file (tar.gz or zip) or by checking out the source files from the Subversion repository.

Source Archive File

  1. Download the source (tar.gz or zip file).
  2. Unpack and change directory to pygraphviz-“version”
  3. Run “python setup.py install” to build and install
  4. (optional) Run “python setup_egg.py nosetests” to execute the tests

Github

  1. Clone the pygraphviz repository

(see https://github.com/pygraphviz/pygraphviz/ for other options)

  1. Change directory to “pygraphviz”
  2. Run “python setup.py install” to build and install
  3. (optional) Run “python setup_egg.py nosetests” to execute the tests

If you don’t have permission to install software on your system, you can install into another directory using the –user, –prefix, or –home flags to setup.py.

For example

python setup.py install --prefix=/home/username/python
or
python setup.py install --home=~
or
python setup.py install --user

If you didn’t install in the standard Python site-packages directory you will need to set your PYTHONPATH variable to the alternate location. Seehttp://docs.python.org/2/install/index.html#search-path for further details.

Requirements

Python

To use PyGraphviz you need Python version 2.6.x or 2.7.x. PyGraphviz does not work with Python 3

The easiest way to get Python and most optional packages is to install the Enthought Python distribution “Canopy” https://www.enthought.com/products/canopy/

There are several other distributions that contain the key packages you need for scientific computing. See the following link for a list: http://scipy.org/install.html

Requirements

GraphViz

To use PyGraphviz you need GraphViz version 2.16 or later. Some versions have known bugs that have been fixed; get the latest release available for best results.
