“dot.exe” not found in path. Pydot on Python (Windows 7)

Question

I\'m having trouble running Python\'s pydot on Windows 7.

I installed pydot with: conda install -c rmg pydot=1.2.2

Answer 1

On Ubuntu 18.04 installing the binaries with sudo apt-get install graphviz led to dot being placed under /usr/bin/dot (it might go to /usr/local/bin/dot per their installation guide). After doing:

pip3 install pydot-ng

and adding the following lines (similar to @Ernest's answer in Linux) to the script it worked:

import os
os.environ["PATH"] += os.pathsep + "/usr/bin/dot"
