on the documentation page for the Trackers,
the code snippet says that you should import Tracker by doing e.g.
from fireworks import Firework, Tracker, ScriptTask, TemplateWriterTask This fails with an ImportError: >>> from fireworks import Firework, Tracker, FWorker, Workflow Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: cannot import name Tracker Doing from fireworks.core.firework import Firework, Tracker, FWorker, Workflow does work. Is importing from fireworks.core.firework the recommended way of importing Fireworks classes? Thanks, Rasmus
