Precog Import Error

GNU Radio
1

I have installed the extras and precog as per wiki.
The gnuradio-comapnion extras blocks are working fine.

But when I try to run precog modules given there is error:-

GRAS: The debug asserts are enabled. <<<
Traceback (most recent call last):

  • File “”, line 1, in *
  • File “/usr/local/lib/python2.7/dist-packages/precog/init.py”,
    line
    29, in *
  • from simple_mac import simple_mac*
  • File “/usr/local/lib/python2.7/dist-packages/precog/simple_mac.py”,
    line
    29, in *
  • import gnuradio.extras #brings in gr.block*
    ImportError: No module named extras

I tried from gnuradio import extras and import gnuradio.extras both.
ImportError: No module named extras

My paths are:-

*export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/dist-packages *
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/
*
*
And I cross checked these folders and they are available at correct
locations.

Precog blocks in companion is also not working while extras blocks are
doing fine! And it says no module named extra!!

Precog requires an older version of grextras on this branch:

You should be able to install it along side the newer grextras without
interfering.
