Re: [Discuss-gnuradio] Python import error on swig modules

[Michael Dickens]

Hi Sakthivel - Glad you found a way to get your GR OOT working. The need for 
adding to PYTHONPATH depends on how the OOT was installed. Usually GR OOTs are 
installed such that you can just "import <module_name>" without having to tweak 
the PYTHONPATH since the "gr" Python stuff is already installed in a place 
where Python can get to it -- the same as where OOTs are installed by default. 
Unless you changes something in the CMakeLists.txt files for how the Python & 
SWIG are installed, then they should go into (by default) 
"/usr/local/lib/python2.7/dist-packages/<module_name>/", which will contain a 
file "__init__.py", which in turn loads all of the actual Python & SWIG stuff. 
You might want to verify the actual OOT Python install for this file. Cheers! -
