I have read as much as I could about thjis but I am stuck and am not making any progress. I have tried to apply a patch as recommended in on the threads around here but that failed.
I am installing from source, downloaded from Github

Here is my command line

c:\Users\MyName\Downloads\pygraphviz\pygraphviz-master>C:\Users\MyName\AppData\L
ocal\Programs\Python\Python35-32\python.exe setup.py install —include-path «C:
Program Files (x86)\Graphviz2.38\include» —library-path «C:\Program Files (x86)
\Graphviz2.38\lib\release\lib»

I am getting this error

Could anybody please please help me with this? I would hate to have to use a different python library for my application

my problem looks quite similar, I am trying around with the following setup:

• Windows7
• Visual Studio Express 2010
• Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:55:48) [MSC v.1600 32 bit (Intel)]
• pygraphviz-1.4rc1.zip

and this is the result, any ideas?

Установка xhprof и Graphviz на Windows

В этой статье я расскажу как установить xhprof и Graphviz на Windows, какие ошибки возникают и как их устранить.

xhprof — php-расширение от facebook. Это иерархический профайлер, который позволяет собирать такую статистику как время выполнения каждой функции, использование памяти, время ожидания, количество вызовов.

Graphviz — пакет утилит по автоматической визуализации графов, заданных в виде описания на языке DOT, а также дополнительных TUI и GUI программ, виджетов и библиотек, используемых при разработке программного обеспечения для визуализации структурированных данных.

Установка xhprof

Сначала скачаем расширение xhprof под Windows.

Вам нужно определить какую версию вам скачивать. На выбор есть две версии PHP 5.3 и 5.4, с Thread Safety или Non Thread Safety (nts).

Чтобы определить какая версия у вас установлена, посмотрите вывод функции phpinfo(). Если в строке «Thread Safety» установлено enabled, значит вам нужно скачивать расширение без nts, и наоборот, если установлено disabled, то скачивать нужно с nts.

Расширение xhprof вам нужно скопировать в директорию ext, где установлен PHP.

В php.ini нужно добавить:
Значение extension у вас может быть другим, смотря какую версию xhprof вы скачали.
Путь «C:/temp/» взят для примера, у вас он может быть другим. Если вы не меняли путь, директория «temp» должна существовать.

Также нам нужно скачать PHP-файлы xhprof и скопировать их в директорию, где расположены файлы сервера.

Installing pygraphviz in Windows 10 — missing basetsd.h

I am having trouble installing pygraphviz on Windows 10 X64 running Python 3.7. I installed graphviz using : pip install graphviz, as suggested here: Pip install pygraphviz fails: Failed building wheel for pygraphviz. I am dont know what needs to be done to get pygraphviz running. Any help would be appreciated. Thanking in advance.

When running pip install pygraphviz, following error is encountered:

Seems you are missing basetsd.h .
Try to download and install Windows 10 SDK.
As you already have Visual Studio compiler, you will need to install only Developer Tools > Windows Headers and Libraries, which includes missing basetsd.h .

Use the following steps to install graphviz and pygraphviz on Windows 10 (64 bit python and graphviz).

Note: If you are running 64bit Python, you need to use 64bit graphviz. I am running anaconda python 3.8.3 (64bit).

Create \Graphviz folder: C:\Program Files (x86)\Graphviz

After unzipping tar, move all folders graphviz folders under Graphviz (\bin, \etc, \fonts, \gtk-2.0, \include, \lib, \pango, \pkgconfig)

Update Path to include: C:\Program Files (x86)\Graphviz\bin

User following pip install:

pip install —global-option=build_ext —global-option=»-IC:\Program Files (x86)\Graphviz\include» —global-option=»-LC:\Program Files (x86)\Graphviz\lib» —no-cache-dir pygraphviz

Graphviz — Graph Visualization Software

For building on Windows:

(Graphviz versions ≥ 2.41)

First, in the root of the repository, perform git submodule update —init . This will download all submodules, which are mostly the dependencies for the Windows build. Next, add the windows\dependencies\graphviz-build-utilities directory to your PATH (and restart Visual Studio or the prompt with which you execute msbuild after that). This folder contains the tools Bison, Flex and SED (and future additions) with versions that are tested. If all went right, the dependencies are now set up and you can build Graphviz.

(Graphviz versions ≥ 2.30)

The current build process for Windows using Visual Studio is fairly simple assuming all of the necessary files are available and have been put in the correct place. The build assumes you have installed binary versions of GTK 2.0 or later, Qt, and ltdl, and source versions of GTS and ann. Further instructions can be found in the Graphviz gitlab repository.

This whole process could and should be simplified. In particular, the 3rd-party software should not be stored in two places, and the Graphviz files that are made part of the release should come from the source package, and not be stored separately. In addition, the GTS and ANN build should be separate from the Graphviz build. As 3rd-party libraries, these should only be built when the source is updated.

(Graphviz versions ≥ 2.22)

We now build both Visual Studio and MinGW versions of Graphviz. In addition, the source package comes with project files for Visual Studio, so building from source should be fairly simple in either case.

• The first step is to add the third-party libraries. These are listed here. This is most easily done by installing a Windows binary version of GTK 2.0 or later.
• Next, download and unwrap the Graphviz source package, and copy over either the stable release or the development source package.

Let $ROOT be the root directory (folder) in which you stored the Graphviz source.

Building with Visual Studio

1. Copy the file $ROOT/windows/config.h into $ROOT.
2. Copy the folder $ROOT/windows/FEATURE into $ROOT.
3. Start Visual Studio and read in $ROOT/graphviz.sln. There are project files for all of the parts of Graphviz.
4. Modify the various settings for include file and library directories to find the third-party software.
5. Modify the settings as to where you want the software installed.
6. Build Graphviz.

Building with MinGW

Install MinGW and Msys. This gives a mini GNU-like compile environment

Set environment variables based on your machine, giving values to the first six below:

Change directory to $ROOT and run configure:

When configure finishes, it lists all of the Graphviz features that have been enabled. If there are problems, you can check for errors in config.log . You may have to add or modify other flags and environment variables for configure to give you the settings you want. Run configure —help to see the allowed options and environment variables.

These builds create a feature-full version of Graphviz. You can tailor them to your wants. This is fairly simple for MinGW: just remove or reset the flag of the option you don’t want. For Visual Studio, you will probably need to reset some of the values in config.h and some of the compile-time options.

(2.21 >= Graphviz versions > 2.14)

To simplify our build process, especially as most Windows users only want a binary version of the software, the Graphviz build for Windows now uses uwin, an open-source Unix layer on top of Windows. In this environment, we can use essentially the same tools and process used on Unix. In particular, we do not have to maintain multiple build files.

To build Graphviz:

• Install the third-party libraries. This is most easily done by installing a Windows binary verion of GTK 2.0 or later.
• Download the Graphviz source package, and copy over either the stable release graphviz- VERSION .tar.gz or the development source package graphviz-working.tar.gz .

Unwrap the package:

You can use, for example,

Let $ROOT be the directory in which you stored the Graphviz source.

Configure the package for your system:

You will probably want to provide additional arguments to configure to indicate where you have installed GTK, where you want the results installed ( —prefix ) and which additional optional packages you want built. Run configure —help to see the available set of arguments.

Presumably, a similar approach would work with Cygwin or MinGW. The following are some notes by Steve Roush describing how he made a static build of the libraries on MinGW.

• Install MinGW and Msys. This gives a mini GNU-like compile environment that produces Windows-compatible results.
• You may need to configure and build in Windows “Safe mode”. Try ./configure in normal mode; if it dies with “fork” problems, use Safe mode.

Edit the “configure” file. after this line:

Как установить graphviz-2.38 на Windows 10

Я знаю, что это просто, но я застрял. Я никогда не устанавливал пакеты Python в ОС Windows раньше. только в Linux.

Я загрузил zip-файл graphviz-2.38 и переместил его в каталог пакетов Anaconda. Я распаковал его, а затем в командной строке попытался:

Это ошибка, которую я получил:

Я не вижу никакого файла установки в Graphviz вообще, поэтому я немного растерялся.

Я столкнулся с той же проблемой и просто pip install graphviz не работал для меня Кроме того, я установил двоичные файлы и установил папку bin в среде Windows PATH переменная, а потом все заработало.

PS это решение устанавливает версию 0.8.2, но работает для keras.utils.vis_utils.plot_model что было проблемой для меня

Если вы используете Conda, запустите следующее: conda install -c anaconda graphviz

Обязательно запустите conda cmd от имени администратора, чтобы избежать ошибок разрешений привилегий. Приведенная выше команда обновит / установит все требования, и graphviz будет доступен в среде по умолчанию в C:\ProgramData\Anaconda3 (для Windows. Не уверен для MAC).

Для меня просто установка graphviz библиотека dint работа. Не смог открыть dot файлы. Поэтому мне пришлось сделать следующее:

1. Скачать конюшню Graphviz версия, нажав Stable 2.38 Windows install packages отсюда
2. устанавливать Graphviz использование библиотеки pip install graphviz
3. Поскольку вы используете Windows, проверьте установленный инструмент под названием GVEdit (просто поиск в меню «Пуск»), он немного облегчает весь процесс.
4. dot файлы можно открыть, выбрав File —> Open
