Re: Performance Counters

[Luke Berndt]

...and I think found atleast some of my problems. gr-perf-monitorx will exit 
with the same error message no matter what the exception is. I changed it to 
print out the Exception. It looks like a number of additional libraries are 
required. To use it I needed to install:
apt-get install libgraphviz-dev
apt-get install graphviz
pip3 install pygraphviz

It also looks like the NetworkX library may have been updated because it is 
complaining about some parameters. I will try to sort through this and submit a 
PR.
