GraphViz visualization of Pytorch NN
Software Engineering:
If installed graphviz using MacPorts, need to add to path to env variables.
import os
os.environ[“PATH”] += os.pathsep + ‘/opt/local/bin/’
To find software installed using MacPorts:
> port installed
To find dirs associated with the software:
> port contents graphviz @9.0.0_0+pangocairo+x11
Deep Learning:
All info propagates in one direction in this one

and a smaller NN:
