I can confirm that the build is successful at this point as I am able to run tests/python/test01.py as long as I add the scattnlay directory to sys.path at the beginning of the test

Good that you had managed to make it work! However, it looks to be like a bug. So, thank you for finding this, I checked it and I can confirm this. I will take a look as soon as I have some time for Scattnlay development....

[dvincentwest]

this issue doesn't happen on Mac OSX Catalina, using a recent Conda python 3.7 environment. Has it been fixed or this is just a different system?

[kostyfisik]

No build changes have been introduced since summer, probably @ovidiopr can clarify this. I was mostly working on a web interface to Scattnlay, see https://physics.itmo.ru/mie/ as a result.
