Hi, I get this error when trying to run python ./top\_block.py

python ./top\_block.py  
Traceback (most recent call last):  
File “./top\_block.py”, line 8, in   
from gnuradio import analog  
ImportError: No module named gnuradio

Do I have to run the python code from a specific dorectory? or set  
variables to gnuradio? or is this another error?

I’m running gnuradio on macports osx 10.10
