I am here again.  I ran "fecapi_async_decoders.grc" with controlport performance moniter on. I made a new config.conf file in ~/.gnuradio and added following lines to it

[ControlPort]
on = True
edges_list = True
[PerfCounters]
on = True
export = True



When I ran the flowgraph I got the following error

I have gnruadio 3.7.8rc1 with networkx1.10 and matplotlib. Also I am on ubuntu 14.04.

Did you try to install pydot?

sudo apt-get install python-pydot

Hi,

Thanks, after installing pydot, the flowgraph is working fine. A warning though, but I think that can be ignored?

 WARN: asynchronous message buffer overflowing, dropping message

There is one thing more. I clicked somewhere in the graph view of performance monitor and following error came, I tried to replicate it but I was not successful.
