Hi, Your own example of ‘airline-demo’ does not work as python module installed in virtualenv. PFA ‘airline-demo’ module exist in remote venv but dagit tells it does not exist.

I am not sure if this is a similar cause but I have problem dynamically importing dagster in virtualenv. Essentially I have a module dagtsrer.py that contains call

importlib.import_module(pipeline)

, where pipeline is a path to dagster pipeline, i.e.

blah/pipeline.py

. When I run

poetry run python  dagtsrer.py --path blah/pipeline.py

I get an error

import dagster_pandas as dagster_pd
  File "/Users/apple/Library/Caches/pypoetry/virtualenvs/pwmf-qUT5bdGW-py3.7/lib/python3.7/site-packages/dagster_pandas/__init__.py", line 1, in <module>
    from dagster.core.utils import check_dagster_package_version
