Graphviz's executables are not found (Python 3.4)

Question

I am running Python3.4 on Windows 7. I am trying to use the Python interface for graphviz. This is a script I intend to run:

from graphviz import Digraph
imp         


        

Answer 1

I also had this problem on Ubuntu 16.04.

Fixed by running sudo apt-get install graphviz in addition to the pip install I had already performed.
