Cannot import gnuradio. Is python set correctly?

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}

When launching gnuradio companion it gives this error message:

Cannot import gnuradio.



Is the python path environment variable set correctly?

    All OS: PYTHONPATH



Is the library path environment variable set correctly?

    Linux: LD_LIBRARY_PATH

    Windows: PATH

    MacOSX: DYLD_LIBRARY_PATH

I do have python 2.7.3 installed.
I installed gnuradio using binaries .deb file from the website below::::
http://ettus-apps.sourcerepo.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux
I do not think the problem from GNURadio something it should be done with those libraries...

In what must be my 6th distinct attempt in as many months to setup and run GNU Radio on Windows, I have finally succeeded! I admit I'm a little delirious with joy and disbelief. I'm answering here because I was getting the exact same error you are, and I suspect you're having the same problem despite the different platform.

What worked for me (after installing GNU Radio binaries from Ettus, including adding it to the path, and installing Python 2.7):

Set PYTHONPATH=[your Python install]Libsite-packages;[GNU Radio install]libsite-packages

pip install pygtk

pip install numpy

pip install lxml

pip install Cheetah

(Note: on Windows, pip installs must be run from elevated command prompt "Run as administrator")

I figured out the problem by launching Python interactively and trying the failing statement from gnuradio-companion.py manually, from gnuradio import gr which gave me ImportError: No module named numpy. That's when it clicked that the module loading was failing while loading its dependent modules, and pip to the rescue to solve that!

I also have been plagued by this problem. I have a solution that works for me, but I am at a loss to explain why it works. I stumbled upon it entirely by accident.

Yes, even though I have Python 2.7 installed, and the diectory is, in fact, named "python2.7". Set the environment to look for "python2.5"

Giving the "env" command at the terminal shows that the "PYTHONPATH" is now set to look for "python2.5"

Now, gnuradio-companion starts up without the error dialog.
