For Unix like systems it is possible to install from source. For Windows this is
overly complicated, and you are recommended to use the binary wheels. There are
two things that are needed by this package: the igraph
C core library and
the python-igraph python package. For both, please see http://igraph.org.
Make sure you have all necessary tools for compilation. In Ubuntu this can be
sudo apt-get install build-essential, please refer to the
documentation for your specific system. Make sure that not only
installed, but also
g++, as the
louvain-igraph package is programmed in
You can check if all went well by running a variety of tests using
There are basically two installation modes, similar to the python-igraph package itself (from which most of the setup.py comes).
Ccore library is installed yet. The packages will be compiled and linked statically to an automatically downloaded version of the
Ccore library of igraph.
Ccore library is already installed. In this case, the package will link dynamically to the already installed version. This is probably also the version that is used by the igraph package, but you may want to double check this.
In case the python-igraph package is already installed before, make sure that both use the same versions.
The cleanest setup it to install and compile the
C core library yourself
(make sure that the header files are also included, e.g. install also the
development package from igraph). Then both the python-igraph package, as well
as this package are compiled and (dynamically) linked to the same
