# Because initially we only copy the lock and pyproject file, we can only install the dependencies
# in the RUN above, as the `packages` portion of the pyproject.toml file is not
# available at this point. Now, after the whole package has been copied in, we run `poetry install`
# again to only install packages, scripts, etc. (and thus it should be very quick).
# See this issue for more context: https://github.com/python-poetry/poetry/issues/1899
