The easiest way to install python-irtk is through conda:

conda install -c kevin-keraudren python-irtk

conda is the package manager that comes with the free Anaconda Python distribution from Continuum Analytics. It is highly recommended for scientific computing in Python as it allows you to install within seconds your favourite libraries, along with their depencies. Additionally, you can easily set up different virtual environments in order to test different versions of some libraries.

See the documentation and notebooks.

To update the documentation:

cd python-irtk/doc/
make html
cd ../../python-irtk-doc/
git add .
git commit -m "rebuilt docs"
git push origin gh-pages
