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

Answer 1

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 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

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

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

Answer 4

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\release\lib" pygraphviz

Answer 5

I've created a build of PyGraphviz 1.5 on my Anaconda channel for Windows 64 bit running Python 3.6 or Python 3.7. 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 6

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
