From the Caffe root directory, you can generate a graph in image format from a .prototxt model file:

#INSTALL PRE-REQS:

$ yum install graphviz

Visualize a CNN in left-to-right:

#goto CAFFE ROOT
$ python/draw_net.py mynetwrk.prototxt mynetwrk.png

Output formats could be : PNG, PDF, DOT or other GraphViz supported formats.
