howto install pygraphviz on windows 10 64bit

Question

Has anyone succeeded in installing pygraphviz on windows 10 64bit? I tried anaconda with python 3.5 64bit & 32bit with no success.

Here is the error I am getting with python 3.5 32bit on win10 64bit

python -m pip install pygraphviz --install-option="--include-path=C:\Program Files (x86)\Graphviz2.38\include" --install-option="--library-path=C:\Program Files (x86)\Graphviz2.38\lib"

Error:

I assume it has something to do with the fact graphviz is linked in 32bit?

Note - I tried all binary for pygraphviz i could found on internet(anaconda,internet), and none work on win10 64bit... if you have any working (i mean you realy tested it ) i would be also happy ...

I've created a build of PyGraphviz 1.5 on my Anaconda channel for Windows 64 bit running Python 3.6 through 3.9. If you're running Anaconda, you can install with:

conda install -c alubbock pygraphviz

This will also install Graphviz 2.41 as a dependency (don't install it separately, it might conflict and not all versions are 64-bit compatible).

I don't currently have a version for Python 3.5 or 32-bit versions of Windows, but I hope the above helps.

This is slightly wrong, and does not work for me. I used `conda install -c alubbock graphviz pygraphviz` – Eduardo Pignatelli Feb 27 '20 at 16:45

@Julio I've just added a Python 3.8 build. Thanks for the reminder! – lubstep Mar 28 '20 at 04:22
this worked for me on windows 10. do `dot -c` after installation – Chidi Sep 30 '20 at 14:59
It didn't include neato. How do I get that to install with graphviz? – Little Bobby Tables Jan 15 '21 at 10:59
Unfortunately lack of neato is a [known issue](https://gitlab.com/graphviz/graphviz/-/issues/1753) in the graphviz Windows release. Hopefully they'll resolve that soon. – lubstep Jan 19 '21 at 00:32
@lubstep You, my man, are an angel. I am so grateful! – Peter May 11 '21 at 18:30
Worked like a charm on Python 3.8! Super great time saver. – cristiandatum Dec 02 '22 at 11:37

The accepted answer didn't work for me running Python 2.7 (Anaconda) on Windows 10. The file path that @MiniMe suggested for --global-option didn't even exist in the git repo that he or she pointed to.

What did work for me was following instructions provided by the (currently) bottom answer to: Installing pygraphviz on windows

Steps:
1. Download graphviz-2.38.msi from https://graphviz.gitlab.io/_pages/Download/Download_windows.html and install
2. Download the 2.7 o̶r̶ ̶3̶.̶4̶ wheel file you need from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygraphviz
3. Navigate to the directory that you downloaded the wheel file to
4. Run pip install pygraphviz-1.3.1-cp27-none-win_amd64.whl
5. Rejoice

N̶o̶t̶e̶ ̶t̶h̶a̶t̶ ̶y̶o̶u̶ ̶m̶i̶g̶h̶t̶ ̶h̶a̶v̶e̶ ̶t̶o̶ ̶r̶u̶n̶ ̶̶p̶i̶p̶ ̶i̶n̶s̶t̶a̶l̶l̶ ̶p̶y̶g̶r̶a̶p̶h̶v̶i̶z̶-̶1̶.̶3̶.̶1̶-̶c̶p̶3̶4̶-̶n̶o̶n̶e̶-̶w̶i̶n̶_̶a̶m̶d̶6̶4̶.̶w̶h̶l̶̶ ̶i̶f̶ ̶y̶o̶u̶'̶r̶e̶ ̶t̶r̶y̶i̶n̶g̶ ̶t̶o̶ ̶g̶e̶t̶ ̶i̶t̶ ̶t̶o̶ ̶w̶o̶r̶k̶ ̶w̶i̶t̶h̶ ̶P̶y̶t̶h̶o̶n̶ ̶3̶.̶4̶.̶ ̶I̶ ̶d̶i̶d̶n̶'̶t̶ ̶t̶e̶s̶t̶ ̶t̶h̶a̶t̶ ̶t̶h̶o̶u̶g̶h̶.̶ Also, the SO answer I referenced also mentioned needing to add graphviz to your PATH but I didn't need to. Good luck!

Update: The python3 wheel vanished. If you're running python3, this answer worked for me. Follow step 1 above and then in WSL bash run:
1. sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config
2. pip install pygraphviz

That answers says to use sudo pip install pygraphviz, but that gave me a dreaded pip import error for some reason. Dropping the sudo made it work in my case.

THe answer I provided was for Python 3.X this is the answer for 2.7 – MiniMe Jul 19 '18 at 14:31
If you're trying to use pygraphviz on windows 10 bash instead, this answer worked for me (https://stackoverflow.com/questions/40528048/pip-install-pygraphviz-no-package-libcgraph-found/42315670#42315670). Basically, just run: `sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config` then `sudo pip install pygraphviz` – rer Oct 10 '18 at 15:51
@r3robertson. where is the python 3.x file? i only see `cp27` 32 and 64 bit versions. – jason Feb 19 '19 at 15:40
@jason I couldn't find the 3.x wheel on that site anymore either. I updated my answer with what worked for me on 3.6. Hopefully that helps. – rer Feb 21 '19 at 15:25
@r3robertson. Thanks. Hopefully someone can find it... i posted a bounty here https://stackoverflow.com/questions/45093811/installing-pygraphviz-on-windows-10-64-bit-python-3-6. I even updated to visual studio 14 and it still doesn't install. – jason Feb 21 '19 at 15:34
@jason Did you try using that other answer? I don't think I ever got it to work with Anaconda btw, I made a virtual environment via WSL, installed pygraphviz on that, and ran a jupyter notebook through that virtual environment. – rer Feb 21 '19 at 16:11
Your python3 link isn't even relevant to windows – Mingwei Samuel Oct 27 '19 at 23:24
This comment gave me the way to install (**python v3.8**, Win10x64): 1. install https://graphviz.gitlab.io/_pages/Download/Download_windows.html 2. add to path C:\Program Files (x86)\Graphviz2.38\bin 3. download https://github.com/CristiFati/Prebuilt-Binaries/blob/master/PyGraphviz/v1.5/Graphviz-2.42.2/pygraphviz-1.5-cp38-cp38-win_amd64.whl 4. run `pip install pygraphviz-1.5-cp38-cp38-win_amd64.whl` 5. profit – Artem Zubkov May 08 '20 at 21:12

Start reading from here https://github.com/pygraphviz/pygraphviz/issues/58

At the bottom of that page there is a link to a x64 zip file in Github (like this) Unpack that. Create a coresponding Program Files folder for your x64 file and put them there

Then install using this

pip install --global-option=build_ext --global-option="-IC:\Program Files\Graphviz2.38\include" --global-option="-LC:\Program Files\Graphviz2.38\lib\" pygraphviz

Here's the link at the bottom of that issues page: https://github.com/mahkoCosmo/GraphViz_x64/. What's strange is that the repo hasn't been updated in 8 months but the `release` directory you're pointing towards in `\Graphviz2.38\lib` doesn't exist. – rer May 16 '17 at 17:57
In my case (Win 10, Python 3.6), additionalIy, had to apply a patch described here https://github.com/pygraphviz/pygraphviz/issues/74#issuecomment-238323405 – José Apr 05 '18 at 15:52
This throws `'graphviz/cgraph.h' : No such file or directory`. – Arthur Attout Mar 20 '19 at 09:01
This works for me, but it does not work if I try to specify these options in the `requirements.txt` file and then read the `requirements.txt` file inside the `setup.py` file to specify the `install_requires`. I get an parse error at `--global-option`. – nbro Jan 12 '21 at 15:04

None of the above worked for me, so I will show what did worked on my windows 11 machine (I don't think the windows version was the problem), which is in the pygraphviz documentation:

Install Visual C/C++, from here: https://visualstudio.microsoft.com/visual-cpp-build-tools/ It shows up as a requirement and even if you did install it and try to reinstall with pip, it may not work because garphviz is another requirement.
Download and install graphviz for windows: stable_windows_10_cmake_Release_x64_graphviz-install-2.46.0-win64.exe
Restart your computer (as required per the first step)
Then install the library pygraphviz through Windows PowerShell with the following command (I don't know why, with pip it still wasn't working):

python -m pip install --global-option=build_ext `
          --global-option="-IC:\Program Files\Graphviz\include" `
          --global-option="-LC:\Program Files\Graphviz\lib" `
          pygraphviz

Works like a charm. Thank you. – Mujeeb Ishaque Feb 11 '22 at 23:15 — Mujeeb Ishaque, Feb 11 '22 at 23:15

It is a real pain to install pygraphviz on Windows 10 but this is the simples solution which works for me:

Step 1: Download and install Graphviz

https://graphviz.gitlab.io/_pages/Download/Download_windows.html

Step 2: Add below path to your PATH environment variable

C:\Program Files (x86)\Graphviz2.38\bin

Step 3: Re-open command line and activate venv in your project, example:

venv\Scripts\activate

Step 4: Download binaries from below link:

https://github.com/CristiFati/Prebuilt-Binaries/tree/master/PyGraphviz/v1.5/Graphviz-2.42.2

Step 5. Install whl into your virtual environment

For example:

In case of python 3.7

pip install pygraphviz-1.5-cp37-cp37m-win_amd64.whl

In case of python 3.8

pip install pygraphviz-1.5-cp38-cp38-win_amd64.whl

thank you, your comment about **adding the Graphviz path to the PATH environment variable** is what finally got this working for me — inconveniently_nonexempt_bee, Dec 02 '21 at 18:18

Here's how I installed 64 bit PyGraphViz for Windows 10:

Downloaded and installed GraphViz from https://www2.graphviz.org/Packages/stable/windows/10/cmake/Release/x64/graphviz-install-2.44.1-win64.exe

Made sure I had Visual C++ installed, e.g. from here: https://visualstudio.microsoft.com/visual-cpp-build-tools/

Then I ran:

pip install --global-option=build_ext --global-option="-IC:\Program Files\Graphviz 2.44.1\include" --global-option="-LC:\Program Files\Graphviz 2.44.1\lib" pygraphviz

Then I had to add C:\Program Files\Graphviz 2.44.1\bin to my system path before import pygraphviz worked.

Finally, I had to run this in command prompt after the install to register plugins and be able to draw graphs: "C:\Program Files\Graphviz 2.44.1\bin\dot.exe" -c

Obviously, for a newer version of Graphviz you'll need to check and update all the paths given above.

The true easiest way to install pygraphviz on Windows without conda or external packager is to use Gohlke's wheels (opinion: His works should be assumed daily by someone in the Python Software Foundation)

Install latest or adapted graphviz package from graphviz using the 64bit or 32bit exe. Don't forget to check the box "add to the path"
Restart the computer
Download Unofficial Windows Binaries for Python Extension Packages by Christoph Gohlke from the Laboratory for Fluorescence Dynamics, University of California, Irvine.
Open a terminal/powershell as admin on the folder where you downloaded the pygraphviz-version-python_version-win_version.whl and enter pip install pygraphviz-*version*-*python_version*-*win_version*.whl
Test the install by opening in the terminal/powershell and entering

python

import pygraphviz

if no error returns, pygraphviz is installed and functional

Try to install from your Anaconda (Python 3.8 recommended) environment using:

conda install -c conda-forge python-graphviz

From these answers graphviz version worked for me is

https://www2.graphviz.org/Packages/stable/windows/10/cmake/Release/x64/graphviz-install-2.44.1-win64.exe

after that I got an error :

kerras plot model AssertionError: "dot" with args ['-Tps', '..\AppData\Local\Temp\tmp334nlu__'] returned code: 1

followed below steps to fix :

1.Open CMD with administrator privileges (simply right click on the CMD and click "run as administrator")

2.Insert the command dot -c, this will configure the GraphViz plugins

If all the solutions above failed, you can still clone directly from the pygraphviz repository

Visit: https://github.com/pygraphviz/pygraphviz.git
Download/Clone it
put the folder into C:\Users\\AppData\Local\Programs\Python\Python37-32\Lib\site-packages
Change directory to “pygraphviz”
Run “python setup.py install” to build and install
(optional) Run “python setup_egg.py nosetests” to execute the tests

Source: http://pygraphviz.github.io/documentation/pygraphviz-1.3.1/install.html

In the step 5, I have the error : basetsd.h not found. Any idea ? — D. O., Apr 22 '20 at 11:24
