USRP error

I have installed gnuradio but when I run a python code, I receive the
following error:

[[email protected] python]# ./usrp_fsk4.py -F test.dat -p 1 >demod_text.txt
Traceback (most recent call last):
 File “./usrp_fsk4.py”, line 32, in
   from gnuradio import gr, gru, usrp, optfir, eng_notation, blks
ImportError: cannot import name usrp

pls some body help me why this error is coming? Should I install USRP
alone again and if so at whcih path?
Thanks,
Teka

Hello Teka,
What OS/platform are you using? What is the value of your PYTHONPATH
environment variable?
Also, check that when you compiled GNU Radio, the USRP module was not
discarded.
