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 ...

Answer 1

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.

Answer 2

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.

Answer 3

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
