I am trying to install GNU Radio manually on my Ubuntu 19.10 by following official instructions( https://wiki.gnuradio.org/index.php/InstallingGR)
When I try to run GNU Radio, this error pops up:
Is the python path environment variable set correctly? All OS: PYTHONPATH
Is the library path environment variable set correctly? Linux: LD_LIBRARY_PATH Windows: PATH MacOSX: DYLD_LIBRARY_PATH
No module named 'gnuradio'
I have checked similar posts on this issue on Stackoverflow, but still could not manage to fix.
How can I correctly set variables based on following current parameters?

You need to add /usr/local/lib/python3/dist-packages to PYTHONPATH environment variable as this directory is not in the default python search paths (sys.path)
Open a new terminal and execute the following
export PYTHONPATH=/usr/local/lib/python3/dist-packages:$PYTHONPATH
gnuradio-companion
to make this change permanent you can add the export line to ~/.profile file. See also Module Not Found Error.
