[Discuss-gnuradio] Problem with tutorial 3 GNU radio in Python

[Shane Petcavich]

Hello, 

I'm having an issue with tutorial3 in https://github.com/gnuradio/gr-tutorial, 
which I have cloned and put into a directory called solutions. I have tried 
this on xubuntu, 3 different installations of ubuntu 14.04 [virtual machines], 
and using the GNURadio Live USB. I have tried installing GNURadio from the 
binary, installing from source, and installing with pybombs. Currently using 
GNURadio 3.7.12.

When trying to run the solution if_else_mod.py in:

examples/tutorial3/python/  

I get the error ' top_block_sptr' object has no attribute 
'analog_sig_source_x_1'

This was previously discussed without much solution here: 
https://lists.gnu.org/archive/html/discuss-gnuradio/2013-11/msg00243.html

Any help would be appreciated. 

Thanks, 
srp
