The API to control the Nova device, does it support python 3?
Python 3 is not supported but is on our roadmap.
In the meantime you could use python’s subprocess library as a hack to use our CLI with Python3. https://docs.python.org/3/library/subprocess.html#module-subprocess
An example would be:
from subprocess import run
run(["sudo", "hologram", "send", "HelloWorld"])
