I’m working on a module with poetry with a directory structure like

./
   /my_module
      (module files)
   /tests
      test_thing.py
   /jupyter
      demo.ipynb

In the test files and jupyter notebooks there is import code like

from my_module import thingy, other_thingy

Now from the project root poetry run pytest works without issue, but invoking jupyter lab via poetry run jupyter lab and then running the notebook results in No module named my_module error. Why is the module on the path for pytest and not jupyter?
