Welcome to GNU Radio! How did you install gnuradio and which version? Which OS

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.
