One possible reason is undefined symbol/reference in your OOT's library (.so) 
file. Go in build directory, execut "ldd -r lib/*.so" and provide the full 
output. Open python/__init__.py and change ImportError to ModuleNotFoundError, 
then rebuild and reinstall.

Please next time copy-paste the text from the terminal and do not attach
