Gr-perf-monitorx Error

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

Executing:
“/home/sdr/gr_examples/gr_fec_def_ex/fecapi_async_decoders.py”

Did you try to install pydot?

sudo apt-get install python-pydot
