As stated on http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux the installation of gnuradio will not necessarily install all dependencies. They recommend to run 

sudo apt-get install python python-wxgtk2.8 pyqt4-dev-tools python-qwt5-qt4 python-numpy libboost-all-dev libusb-1.0.0-dev
I would also recommend to install the GNU Radio with Ettus repositories instead of the ones of Ubuntu.

Hi, I am trying to install gnuradio on Kubuntu 14.04 64 bit. I am using the binaries from the main Ubuntu software repository to install the same by running the following: sudo apt-get install gnuradio The installation works fine. However, when I tried running gnuradio-companion, I got the GUI indicating the following: Cannot import gnuradio. Is the python path environment variable set correctly? All OS: PYTHONPATH I felt that this could be due to the fact that I have Anaconda's Python installed, which I do so for several reasons. So, my Python runs from /home/nipun/anaconda/bin as opposed to the default Ubuntu path. I verified this by importing gnuradio from Python run by /usr/bin/python as opposed to Anaconda's python (/home/nipun/anaconda/bin/python). I could import gnuradio from /usr/bin/python. This suggests that gnuradio picks up the default Ubuntu python location. I then uninstalled gnuradio using sudo apt-get remove gnuradio and set my PATHS as in .bashrc, did a sudo ldconfig and source .bashrc. My paths at this point were as follows: address@hidden:~$ echo $LD_LIBRARY_PATH /usr/lib32:/home/nipun/anaconda/bin:/usr/local/lib address@hidden:~$ echo $PYTHONPATH /home/nipun/anaconda/bin: However, even after this point, gnuradio would work from default Ubuntu path only. Also, gnuradio-companion would naturally complain and not startup. Question 1: How can we set custom Python path for gnuradio to install to? Question 2: Anaconda has made life much easier for the scientific Python community. It makes installing on Windows, Mac and Linux pretty easy. Also, dependencies such as numpy, scipy, etc. are also taken care of. Would the gnuradio team consider putting up a package on Anaconda. The Anaconda team look pretty helpful and should be willing to help. I think that this can save a lot of questions on installation related questions across different environments.
