One possible reason for errors like this one is undefined references in the 
shared object files. To check if this is the case go in the cmake build 
directory of you OOT module and execute

  ldd -r ./swig/*.so
  ldd -r ./lib/*.so

To resolve this add all your *.cc/*.cpp files in lib/CMakeLists.txt, add the 
-Wl,--no-undefined to link flags

  set_target_properties(gnuradio-tmp PROPERTIES LINK_FLAGS "-Wl,--no-undefined")

open python/__init__.py and remove the try except block around swig import line

   from .tmp_swig import *
