You must have Python 3 and pip installed.
Install script dependencies using pip: `pip install -r requirements.txt`
Then to run script: `python ava.py myRoom`

Linux will likely forbid global Python packages installation so virtualenv is required. 
Install dependencies into virtualenv and launch provided bash script: `ava myRoom`
Script expects dedicated virtualenv to exist at `~/python_venvs/ava/bin/activate` and python script itself to be put at `~/scripts/availaunch_python/`

And dont forget to add executable permission to both bash and python scripts
