[Discuss-gnuradio] "from gnuradio import gr"

[Charles Chen]

Hi All,

  I have everything installed and was trying to run
./usrp_oscope.py according to the instructions at
http://comsec.com/wiki?UsrpInstall . However, I get an
error when I try to run the file.

address@hidden usrp]# ./usrp_oscope.py
Traceback (most recent call last):
  File "./usrp_oscope.py", line 23, in ?
    from gnuradio import gr
  File
"/root/gr/lib/python2.3/site-packages/gnuradio/gr/__init__.py",
line 29, in ?
    from flow_graph import *
  File
"/root/gr/lib/python2.3/site-packages/gnuradio/gr/flow_graph.py",
line 26, in ?
    from gnuradio_swig_python import buffer,
buffer_add_reader, block_detail, \
ImportError: cannot import name buffer

  So the problem is, I can import gnuradio, wx, and
Numeric but when i try to import gr from gnuradio it
won't work. Here's what happens:

address@hidden usrp]# python
Python 2.3.5 (#1, Jun 29 2005, 14:26:55)
[GCC 3.2.3 20030502 (Red Hat Linux 3.2.3-20)] on
linux2
Type "help", "copyright", "credits" or "license" for
more information.
>>> import gnuradio
>>> import wx
>>> from gnuradio import gr
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File
"/root/gr/lib/python2.3/site-packages/gnuradio/gr/__init__.py",
line 29, in ?
    from flow_graph import *
  File
"/root/gr/lib/python2.3/site-packages/gnuradio/gr/flow_graph.py",
line 26, in ?
    from gnuradio_swig_python import buffer,
buffer_add_reader, block_detail, \
ImportError: cannot import name buffer

  I have been stuck on this problem for a long time.
Hope that I can get some suggestions. Thanks everyone.
