Re: [Discuss-gnuradio] usrp examples (ignore earlier)

[Prateek Dayal]

I once faced this error and tried real hard to get away with this in a
gentleman's way ... but in the end I just deleted my site packages
folder completely and reinstalled gnuradio and other things and it
worked ...

but I am sure that there has got to be a better way .,...

the problem came up when i wrote a module of my own and added it to
other things ...

Regards
