The pip install . command does not install packages inside ukfm folder to install the we should use pip install . -vvv reference : https://stackoverflow.com/questions/50585246/pip-install-creates-only-the-dist-info-not-the-package

For me, modification of the package parameter was required, based on your stackoverflow solution : packages=['ukfm', 'ukfm.geometry', 'ukfm.model', 'ukfm.ukf'] (setup.py, line 11)
