When trying to create a dagster repository as a separate python package in https://github.com/geoHeil/dagster-demo/tree/master/use_cases/usecase_b I have installed it with:

pip install .

A manual import:

from usecase_b.hello_b import hello

works nicely. However, when trying to start dagit I get a stacktrace of:

No module named 'hello_b'
