Thanks, Vasil finally I reinstalled UHD 4.1.0.5 and Gnuradio 3.8.1 now a simple example RFNOC block works, 

I added ettus_rfnoc_graph block to GRC file, now everything is ok. I share screenshot.

This is not a problem, this is the gr-ettus' version https://github.com/EttusResearch/gr-ettus/blob/master/CMakeLists.txt#L32-L36

The output is OK, no undefined symbols.

Have you tried changing ImportError to ModuleNotFoundError in python/__init__.py and do you still get the same error after reinstalling?

Which gr-ettus version did you install and from which git commit id?

Provide the full list of files in /usr/local/share/gnuradio/grc/blocks?
