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

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.
