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 ...

its solved here for windows 10 – Exonerate

Answer 1

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

Farrica

Here's the link at the bottom of that issues page: 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. – Fork

In my case (Win 10, Python 3.6), additionalIy, had to apply a patch described here github.com/pygraphviz/pygraphviz/issues/… – Busybody

This throws 'graphviz/cgraph.h' : No such file or directory. – Coterminous

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. – Fogbow

Answer 2

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.

Gable

saved me a lot of time. Thanks :) – Ewart

This is slightly wrong, and does not work for me. I used conda install -c alubbock graphviz pygraphviz – Jd

@Julio I've just added a Python 3.8 build. Thanks for the reminder! – Gable

this worked for me on windows 10. do dot -c after installation – Demarcate

It didn't include neato. How do I get that to install with graphviz? – Fairleigh

Unfortunately lack of neato is a known issue in the graphviz Windows release. Hopefully they'll resolve that soon. – Gable

@Gable You, my man, are an angel. I am so grateful! – Toolmaker

Worked like a charm on Python 3.8! Super great time saver. – Hexangular

Answer 3

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.

No quite sure why this got a zero score, but it worked for me as well. – Anett

THe answer I provided was for Python 3.X this is the answer for 2.7 – Farrica

If you're trying to use pygraphviz on windows 10 bash instead, this answer worked for me (#40528548). Basically, just run: sudo apt-get install python-dev graphviz libgraphviz-dev pkg-config then sudo pip install pygraphviz – Fork

@r3robertson. where is the python 3.x file? i only see cp27 32 and 64 bit versions. – Collogue

@Collogue 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. – Fork

@r3robertson. Thanks. Hopefully someone can find it... i posted a bounty here #45094311. I even updated to visual studio 14 and it still doesn't install. – Collogue

@Collogue 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. – Fork

Your python3 link isn't even relevant to windows – Agbogla

This comment gave me the way to install (python v3.8, Win10x64): 1. install graphviz.gitlab.io/_pages/Download/Download_windows.html 2. add to path C:\Program Files (x86)\Graphviz2.38\bin 3. download github.com/CristiFati/Prebuilt-Binaries/blob/master/PyGraphviz/… 4. run pip install pygraphviz-1.5-cp38-cp38-win_amd64.whl 5. profit – Boor

was missing those additional libraries on ubuntu 22. installing them allowed me to install pygraphviz on python 3.10. Thank you – Dmitri

How do i install it in windows without using WSL bash? – Icicle

Answer 4

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:

1. 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.
2. Download and install graphviz for windows: stable_windows_10_cmake_Release_x64_graphviz-install-2.46.0-win64.exe
3. Restart your computer (as required per the first step)
4. 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. – Heger

Answer 5

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

Success

thank you, your comment about adding the Graphviz path to the PATH environment variable is what finally got this working for me – Creamcups

NOTICE: This does NOT work for python version > 3.8. – Heger

Answer 6

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.

Answer 7

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)

1. 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"

2. Restart the computer

3. Download Unofficial Windows Binaries for Python Extension Packages by Christoph Gohlke from the Laboratory for Fluorescence Dynamics, University of California, Irvine.

4. 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

5. Test the install by opening in the terminal/powershell and entering

   python

   import pygraphviz

if no error returns, pygraphviz is installed and functional

Answer 8

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

conda install -c conda-forge python-graphviz

Answer 9

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

Answer 10

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

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