Installation

Using Conda

Conda will install GCG, SCIP and PySCIPOpt automatically, hence everything can be installed in a single command:

conda install --channel conda-forge pygcgopt

Installing PyGCGOpt from PyPI

Simply run the following to install PyGCGOpt (and its requirement PySCIPOpt) with pip:

pip install PySCIPOpt
pip install PyGCGOpt

The following table summarizes which versions of PyGCGOpt and PySCIPOpt are compatible:

PySCIPOpt	PyGCGOpt
5.2.1	0.4.0
5.3.0	0.4.1

Testing new installation

To test your brand-new installation of PyGCGOpt you need pytest on your system.

pip install pytest

Here is the complete installation procedure.

Tests can be run in the PyGCGOpt directory with: :

py.test # all the available tests
py.test tests/test_name.py # a specific tests/test_name.py (Unix)

Ideally, the status of your tests must be passed or skipped. Running tests with pytest creates the __pycache__ directory in tests and, occasionally, a model file in the working directory. They can be removed harmlessly.
