Hello ,
 I have completely installed Gnuradio-3.1.3 on RHEL4.Even I have
uploaded the firmware on the usrp.But when i was trying to run
usrp_fft.py i got the attribute key error.After searhing through all
forum i gor to know that Python 2.3 could not update the numpy's
directories.So i downgraded Numpy to 1.0.4 and now i m getting the
following errors:-
