Help! ImportError: cannot import name usrp

GNU Radio
1

Hi,

Just started on this project again and faced with this problem with the
gnuradio-3.1.3 version using fedora 9. The error message occured when i
was running gr-utils/src/python/usrp_fft.py

I am logging in as root.

The error reported is as shown:
Traceback (most recent call last):
File "usrp_fft.oy, line 24, in
from gnuradio import usrp
ImportError: cannot import name usrp

Your help is much appreciated. =)

Dear jorren

check your python path
your python can not found the module.

In my memory, you can find some discussion here (same error message)

Hi,

my python path is correct but i can’t find any past discussions
regarding the same error message on google. May i check where can i find
the past discussions?

Hi,

sorry, it was a typing mistake.

I realised that gr-usrp, usrp and gr-utils weren’t configured so was
wondering if that is the main cause of the problem? Cos i checked that
the python path is correct.

Hi,

This may be one of the more stupid things I’ve said here (or any were
else), but shouldn’t it be
“usrp_fft.py”, and not “usrp_fft.oy”? It seems like an easy typo to
make, and when i do:
“$slocate usrp_fft.oy” nothing shows up, but when i do: “$slocate
usrp_fft.py” a whole bunch of files scattered all over the place shows
up… just a thought…

Need more Info:
Did you compile by yourself or did you use distribution packages?
What exactly did you do do install GNU Radio?
What was the exact command line you entered to start the program?

I downloaded gnuradio-3.1.3, i don’t really get what u mean by compile
by myself or using distribution package.

For some systems, you can install GNU Radio via the package management
systems. On ohters you have to get the sourcecode and compile it by
yourself.

i did
./configure
make
make check
sudo make install

following exactly the same steps that was illustrated in the build
guide.

Which build guide did you follow?

didn’t know where went wrong but gr-utils, usrp and gr-usrp was
not configured during the ./configure command.

Have you checked the output of ./configure? Usually failed checks give a
good hint what went wrong.

Did you read the README? Did you go through the instructions at
http://gnuradio.org/trac/wiki/FedoraInstall?

Please guide me. Thank you so much!

Please help us help you.
