Can not import digital_swig for the example of pkt.py

I am using the this example to test the installed next branch of josh:

http://gnuradio.org/cgit/jblum.git/tree/gr-digital/python/pkt2.py?h=next

How ever, the digital_swig is not recognized. And I also checked the
changeset at
http://gnuradio.org/redmine/projects/gnuradio/wiki/ChangeSets

Nothing related is found.

Traceback (most recent call last):
File “./pkt2.py”, line 23, in
import digital_swig
ImportError: No module named digital_swig

Can someone tell me where to find this package now?

Alex,
Dreams can come true just believe.

It looks like you have some left-over code laying around. The pkt2.py is
gone and we use pkt.py now, instead. Something must have gotten left
behind
with a checkout or merge at some point.

As for the digital_swig, that’s the “real” name of the SWIG’d-up
gr-digital
module that we export into digital. The internal gr-digital python
modules
use digital_swig, though.

Make sure you’ve cleaned up previous installs, to a git clean -dxf in
your
gnuradio checkout and reinstall. Hopefully that’ll fix your problems.

Just found the digital_swig.py is located
at /usr/local/lib/python2.7/dist-packages/gnuradio/digital
So I change “import digital_swig” to “from gnuradio.digital import
digital_swig” and the complaining disappeared. Seems for these python
modules, i still need to give a full path, even I have imported the
gnuradio, gnuradio.digital in the beginning of the code.

Here is my digital python directory, what is yours missing that mine
has?

Sorry for the correction, pkt2 is my doing. I re-implemented pkt.py with
message passing capabilities.

I think Alex is importing pkt2.py from in-tree and not from an installed
location.

Hi Josh,

I have no d8psk*, dbpsk*, modulation_utils2*.
Which branch do you use for this?

The dXpsk blocks have been replaced with Xpsk modulators that allow both
differential and non-differential with a flag to turn it on and off
(should
be on by default), and modulation_utils2 (unless Josh reintroduced that,
too) is now must modulation_utils.

I updated the ChangeSets wiki page to mention this explicitly:
