Usrp2 import error

GNU Radio
1

Hi -

Sorry for such a newbie question, but I am trying to get my USRP2 up and
running and am having some issues. I’m running Ubuntu 9.04 (Jaunty) and
have installed the stable release of gnuradio 3.2 using the binary
package
instructions at:

http://gnuradio.org/redmine/wiki/gnuradio/DebianPackages

When I open up a python shell, I can successfully import gr and usrp,
however I get an import error if I try to import usrp2. In other words,
“from gnuradio import usrp” works just fine, however “from gnuradio
import
usrp2” does not. It results in the usual “ImportError: cannot import
name
usrp2”. I’ve read the post here:

http://www.mail-archive.com/[email protected]/msg23926.html

but it was not very helpful because I have nothing listed in my
/usr/local/lib/python2.6/dist-packages/ or
/usr/local/lib/python2.6/site-packages/ directories, and
/usr/lib/python2.6/
contains neither dist-packages or site-packages.

Also, just in case it may matter, I am running the 2.6.28 kernel, with a
64-bit install on a sony vaio.

Thanks,
Rob

The gnuradio deb packages are split into many sub-components, you are
probably missing the gnuradio-python. I search your package manager for
gnuradio and see which packages are unchecked. -Josh

Thanks, Josh:) I did a quick search in my package manager for
“gnuradio” and
I was missing quite a few. I believe the culprit was
“python-gnuradio-usrp2”.
Thanks again,
Rob

If you install ‘gnuradio-companion’, this will ultimately pull in all
the GNU Radio packages except the C++ development headers.

What’s a bit funny is that I initially followed the directions at
http://gnuradio.org/redmine/wiki/gnuradio/DebianPackages, which
includes:

$ sudo aptitude install gnuradio gnuradio-companion

Perhaps I didn’t see an error message but I’m sure I ran that command:)
