Why is pydot unable to find GraphViz's executables in Windows 8?

Question

I have GraphViz 2.32 installed in Windows 8 and have added C:\\Program Files (x86)\\Graphviz2.32\\bin to the System PATH variable. Still pydot is unable to find its executab

Answer 1

after doing all the installation of graphviz, adding to the PATH of environment variables, you need to add these two lines:

import os
os.environ["PATH"] += os.pathsep + 'C:/Program Files (x86)/Graphviz2.38/bin/'
