I found the answer to this post in the discuss-gnuradio archive. The
answer was posted by Patrick Sathyanathan:
[Discuss-gnuradio] OOT Module Attribute Error module object has no
attribute 'blockname'
<http://lists.gnu.org/archive/html/discuss-gnuradio/2015-08/msg00374.html>
The problem I had was exactly as Patrick describs, as was the solution.
I'd recommend putting this information on the new Wiki!

I periodically run into problems with the Python/SWIG portion of my
out-of-tree module builds. Wrapper modules are built by swig but
appear empty.
I'm running Ubuntu 16.04.
The error I get when I try to run a typical flowgraph that uses my
"abc_module" from GRC is
--------
Using Volk machine: avx2_64_mmx_orc
[...]
AttributeError: 'module' object has no attribute 'periodic_burst_source'
-------
SWIG appears to run and generate the wrapper files during the make,
but the wrapper files don't have the interface. I thought I'd fixed
this by reinstalling GNU radio, but now a module that once built
properly is failing as above. I can run python and "import abc_module"
but "Dir(abc_module)" shows it to be empty.
There are multiple SWIG distribution/versions available. At one point
I thought switching to SWIG 3.0 fixed this issue but the last time it
cropped up switching to 3.0 had no effect.
Also, the "make install" installing wrappers in
/usr/local/lib/python2.7/dist-packages, though on another machine I
have it has installed wrappers in /usr/lib/python2.7/dist-packages.
Does anyone have tips or advice on debugging these issues?
Thanks,
Dan
