"RuntimeError: Make sure the Graphviz executables are on your system's path" after installing Graphviz 2.38

Question

You should install the graphviz package in your system (not just the python package). On Ubuntu you should try:

sudo apt-get install graphviz

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

In windows just add these 2 lines in the beginning, where 'D:/Program Files (x86)/Graphviz2.38/bin/' is replaced by the address of where your bin file is.

That solves the problem.

This one solved the problem for me on MAC:

  brew install graphviz

For Windows:

1. Install windows package from: https://graphviz.gitlab.io/_pages/Download/Download_windows.html
2. Install python graphviz package
3. Add C:\Program Files (x86)\Graphviz2.38\bin to User path
4. Add C:\Program Files (x86)\Graphviz2.38\bin\dot.exe to System Path

This worked for me!

Try using:

conda install python-graphviz

The graphviz executable sit on a different path from your conda directory, if you use pip install graphviz.

Step 1: Install Graphviz binary

Windows:

1. Download Graphviz from http://www.graphviz.org/download/
2. Add below to PATH environment variable (mention the installed graphviz version):
   • C:\Program Files (x86)\Graphviz2.38\bin
   • C:\Program Files (x86)\Graphviz2.38\bin\dot.exe
3. Close any opened Juypter notebook and the command prompt
4. Restart Jupyter / cmd prompt and test

Linux:

1. sudo apt-get update
2. sudo apt-get install graphviz
3. or build it manually from http://www.graphviz.org/download/

Step 2: Install graphviz module for python

pip:

• pip install graphviz

conda:

• conda install graphviz
