GiganticTurtle0 so this was already supposed to be out (v1.1) but a minor py2 backwards compatibility delayed it. Anyhow you can now just call pipeline.start(..)

(to run it locally call start_locally(...) )
pip install git+(the new version will be out in a few days, meanwhile you can test the new pipeline interface directly from git)
