Please clarify the command leading to the error:

- running pytest and some unmentioned test file
(which contains what code) testing baz.py

- running ~/project/utils/baz.py as a script from the project-directory

- running a some unmentioned project-script which calls baz.py 
successfully, before baz.py fails

- something else
