No module named gnuradio

GNU Radio

Hello,
I have recently installed gnuradio-3.1.3 on Red Hat Enterprise Linux
4.I can even load the firmware on the usrp using ./test_usrp_standard_tx
.But after the loading of the firmware whenever i try to run the
./usrp.oscope.py program I get the “No module named gnuradio” error.

[root@localhost python]# ./usrp_oscope.py
Traceback (most recent call last):
File “./usrp_oscope.py”, line 25, in ?
from gnuradio import gr, gru
ImportError: No module named gnuradio

I have even set the PYTHONPATH to desired directory.I get the following
result whenever i print the sys.path in python :

[root@localhost python]# python
Python 2.4.6 (#1, Mar 30 2009, 13:30:46)
[GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)] on linux2
Type “help”, “copyright”, “credits” or “license” for more information.

import sys
sys.path
[’’, ‘/usr/local/lib/python2.4/site-packages’,

‘/usr/local/lib/python2.4/lib-dynload’,
‘/usr/lib/python2.3/site-packages/wx-2.5.3-gtk2-ansi’]

Did you install via the package management system or did you compile
yourself? Please provide the sommand sequence you used.

For better readability, please consider following rules:

  • never a space before punctuation (,;:.!?).
  • always a space after punctuation.
  • For better readability it is common, but not compulsory, to add a
    second space after sentences. See this sentence as example. But only
    after full stops (.).

Your PATH looks like if there is some PATH
missing. Try to add the PATH with:
sys.path.append(‘directories to gnuradio python libs’)

But you should know that your system seems to be missconfigured.
Are you really using Python2.4 ???
And what shall the ‘’ in your PATH ?

My PATH looks like this,
[‘/home/markus/Documents/gnuradio-projekt/versuche/usrp-AM’,
‘/usr/lib/python26.zip’,
‘/usr/lib/python2.6’,
‘/usr/lib/python2.6/plat-linux2’,
‘/usr/lib/python2.6/lib-tk’,
‘/usr/lib/python2.6/lib-old’,
‘/usr/lib/python2.6/lib-dynload’,
‘/usr/lib/python2.6/site-packages’,
‘/usr/lib/python2.6/site-packages/Numeric’,
‘/usr/local/lib/python2.6/site-packages’,
‘/usr/lib/python2.6/site-packages/gtk-2.0’,
‘/usr/lib/python2.6/site-packages/wx-2.8-gtk2-unicode’]

In my python PATH i installed my gnuradio python modules.
Maybe search for my name to get more information on installation
and reinstall gnuradio correctly.
