Multiple issue here.
Ansible cannot be installed as a lib. Workaround is to install via pip before installing kalliope.

Flask testing lib: jarus/flask-testing#143
The issue is fixed but not released into pypi.

I forced the Werkzeug version to a previous release.
And the Ansible installation is performed before the kalliope install.

Level expects an int and the default value isNone. it can lead to type incompatibility in the next linesm such as self.level - current_level.
Maybe we could replace the default value to 0

Sorry i merged before answering. I saw that you approved.
Anyway, the level is tested in the method below. It will fail if it's not an integer. And this parameter is mandatory.
