In case you are using Linux then check if you have undefined symbols/references in the .so (shared object) file. Go in your OOT's build directory and execute ldd -r lib/lib*.so and provide the full output. Also open `python/__init__.py`, change `ImportError` to `ModuleNotFoundError` and then reinstall and retest. Best Regards, Vasil
