A possible reason for errors like above is undefined reference/symbol in the OOT's shared object (.so) file. Go in the gr-ettus' build director, execute "ldd -r ./libs/libgnuradio-ettus.so" and provide its full output.

Also open python/__init__.py, change ImportError to ModuleNotFoundError then rebuild and reinstall.
