In this repository are the code examples.
You need Python 3.5 for the examples. It's the newest production version of Python that was finalized in September 2015, so you might not have it yet. If you happen to run Ubuntu Linux, I can recommend this PPA to get Python 3.5 on a distro version that doesn't have it yet.
For example 2, you need the pip packages listed in pip3-req.txt.
pip3 install -r pip3-req.txt should do the trick. Preferably locally in a virtualenv:
python3.5 -m venv py-env . ./py-env/bin/activate pip3 install -r pip3-req.txt
