Installing¶
Quick Install¶
Get PyGraphviz from the Python Package Index at http://pypi.python.org/pypi/pygraphviz
or install it with:
pip install pygraphviz
and an attempt will be made to find and install an appropriate version that matches your operating system and Python version.
You can install the development version (at github.com) with:
pip install git://github.com/pygraphviz/pygraphviz.git#egg=pygraphviz
Get PyGraphviz from the Python Package Index at http://pypi.python.org/pypi/pygraphviz
or install it with:
easy_install pygraphviz
and an attempt will be made to find and install an appropriate version that matches your operating system and Python version.
Providing path to graphviz¶
We tried our best to discover graphviz location automatically, but if you would like specify specific location for graphviz you may provide additrional parameters to specify graphviz location
include-path= path to graphviz include files library-path= path to graphviz library files
For example
python setup.py install --include-path=/usr/local/Cellar/graphviz/2.38.0/include/graphviz --library-path=/usr/local/Cellar/graphviz/2.38.0/lib
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¶
- Download the source (tar.gz or zip file).
- Unpack and change directory to pygraphviz-“version”
- Run “python setup.py install” to build and install
- (optional) Run “python setup_egg.py nosetests” to execute the tests
Github¶
Clone the pygraphviz repository
(see https://github.com/pygraphviz/pygraphviz/ for other options)
- Change directory to “pygraphviz”
- Run “python setup.py install” to build and install
- (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¶
PyGraphviz is tested and works with Python 2.7 and Python 3.4. It may work correctly with other Python 3.x versions.
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.
