Re: what is gateway.py

[Johannes Demel]

Hi,

If you use a Python block, you use `gateway.py`. Under the hood, this 
file provides the functionality that binds Python and GR together to be 
able to call Python code during runtime. Everywhere else GR uses Python 
to configure flowgraphs but the actual flowgraph execution is entirely 
implemented in C++.

The actual error seems to be related to a missing configuration. However 
it is terribly hard to tell without more info.

Cheers
Johannes
