I have installed gnuradio3.1.3 and executed the ‘export
PYTHONPATH=/usr/local/lib/python2.5/site-packages’ command. Then,
the command ‘from gnuradio import usrp’ doesn’t result in an error when
executed from the gnuradio folder
but when I cd to my custom demodulator block which is also located on
the gnuradio folder, and execute my python file, it outputs
the following error:
[root@localhost python]# ./usrp_fsk4_oscope.py
Traceback (most recent call last):
 File “./usrp_fsk4_oscope.py”, line 26, in
   from gnuradio import usrp
ImportError: cannot import name usrp
I have tried several times but it still gives out the same error. I have
also installed all the dependencies for the gnuradio
for fedora and used ‘./configure --enable-all-components’ option when I
install the gnuradio. I don’t have the USRP hardware now
but I want to take input from local files instead of the usrp.
Any suggestions please!
Thanks,
