Re: ImportError: No module named baz_swig

[Ian Bennett]

Cinaed,
        Thanks for the reply.
	librtlsdr-dev was already installed. The other two were not and pulled in some other dependencies 
during the install process.
        This did not fix my problem though.
	I couldn't install gr-baz from the ubuntu repo so followed the build process for gr-baz on github. 
I could then get it to run, but with no output.
	After further reading, the website recommends a minimum version of 3.8. I note that 3.9 is 
available via a PPA so will install that and work through the tutorials (which I didn't find 
yesterday). Must have had a "man" look ;-)
        Thanks again for your assistance.

Ian
