Do you see a qtgui directory under your
$prefix/lib/python2.6/site-packages/gnuradio? If that’s there, then
you should be able to import it.
Yes, the qtgui folder is there and there are a couple of files in it.
If it’s not, then something’s gone
wrong in the build/install process. What OS are you running?
I’m running Fedora 12 x86 64-bit.
