How to install graphviz-2.38 on windows 10

Question

I know this is basic, but I'm pretty stuck. I've never installed python packages on Windows OS before... only Linux.

I downloaded the graphviz-2.38 zip and moved it to my Anaconda packages directory. I unzipped it, and then on the command line tried:

C:\Users\name\Anaconda3\pkgs\graphviz-2.38> pip install graphviz-2.38

This is the error I got:

Could not find a version that satisfies the requirement graphviz-2.38 (from 
versions: )
No matching distribution found for graphviz-2.38

I don't see any setup file within graphviz at all, so I'm a little lost.

Wow. That worked! I feel crazy for the answer being that simple. Thank you!! — adurbin, Jul 14 '17 at 01:23

I faced the same issue and just pip install graphviz didn't work for me. In addition, I installed the binaries and set the bin folder in the Windows environment PATH variable, and then it worked.

P.S. this solution installs the 0.8.2 version but works for keras.utils.vis_utils.plot_model which was the problem for me

Confirmed working on Win 10 with recent Tensorflow 2.1 install (GPU included) also to get `tensorflow.python.keras.utils.vis_utils.plot_model` working. Installed pydot, pydotplus and graphviz in that order with `pip install ...` then followed this step... including refreshing PATH (e.g. close and reopen `cmd` window before re-running .py script) – omatai May 06 '20 at 00:16
for me worked on Win10 for pyAgrum library. Thanks for the tip. – Helder Jun 02 '20 at 15:41

If you are using Conda, then run the following: conda install -c anaconda graphviz

Be sure though to run the conda cmd as Admin for avoiding privileges permission errors. The above command will update / install all the requirement, and graphviz will be available in the default environment at C:\ProgramData\Anaconda3 (for windows...Not sure for MAC).

For me just installing the graphviz library dint work. It was not able to open dot files. So I had to do the following:

Download the stable Graphviz version by clicking Stable 2.38 Windows install packages from here
Install Graphviz library using pip install graphviz
Since you're using windows, check out the installed tool called GVEdit (just search in the start menu), it makes the whole process slightly easier.
The dot files can be opened by selecting File --> Open

I got "GraphViz's Executables not found" when I tried the program "https://www.w3schools.com/python/showpython.asp?filename=demo_ml_dtree4"

I tried

"pip install graphviz" or
"conda install graphviz". Both of them didn't work for me.

I solve the problem for WIndows-10 as follows:

Go to Graphviz web site: http://wingraphviz.sourceforge.net/wingraphviz/
Setup environment variables, path="...;c:\Program Files (x86)\Graphviz2.38\bin;"
Save the path
From the command Prompt check the "Graphviz" path.
Re-execute the program, the tree is visualized now.

I tried

pip install graphviz
conda install graphviz

Both of them didn't work for me.

Adding to the path seem to be the solution. Since I don't have admins right. I can do this temporarily within a script:

import os
os.environ["PATH"] += os.pathsep r"C:\Users\Nameuser\Anaconda3\Library\bin\graphviz"
