"RuntimeError: Make sure the Graphviz executables are on your system's path . "在安装Graphviz 2.38之后

我下载了Graphviz 2.38 MSI版本，安装在C:\Python34文件夹下，然后运行pip安装Graphviz，一切顺利。在系统路径中我添加了C:\Python34\bin。当我试图运行一个测试脚本，在行filename= .render(filename='test')，我得到了一个消息

 RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path

我尝试将“C:\Python34\bin\dot.exe”放在系统路径中，但它不起作用，我甚至创建了一个新的环境变量“GRAPHVIZ_DOT”，其值为“C:\Python34\bin\dot.exe”，仍然不起作用。我尝试卸载Graphviz和pip uninstall Graphviz，然后重新安装它和pip install，但没有任何工作。

整个回溯消息是:

Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\graphviz\files.py", line 220, in render
    proc = subprocess.Popen(cmd, startupinfo=STARTUPINFO)
  File "C:\Python34\lib\subprocess.py", line 859, in __init__
    restore_signals, start_new_session)
  File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Users\Documents\Kissmetrics\curves and lines\eventNodes.py", line 56, in <module>
    filename=dot.render(filename='test')
  File "C:\Python34\lib\site-packages\graphviz\files.py", line 225, in render
    'are on your systems\' path' % cmd)
RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test'], make sure the Graphviz executables are on your systems' path

有人有经验吗?

你可以在Anaconda提示符中使用以下命令:

Conda Install python-graphviz

确保在Anaconda提示符中安装pm4py:

PIP安装pm4py

最后，你必须尝试使用Anaconda提示符运行你的python代码。

1) Graphviz -在系统的特定位置下载解压缩(pip在windows中不起作用)，并在每个程序中手动设置的路径(' set environment variables in windows ' OR)中包含bin文件夹

import os
os.environ["PATH"] += os.pathsep + 'C:/GraphViz/bin'

2)然后将模型放到图中

clf = xgb.train(params, d_train, 1000, evals=evallist, early_stopping_rounds=10)
xgb.plot_tree(clf)
plt.rcParams['figure.figsize'] = [50, 10]
plt.show()

conda install python-graphviz

对于Windows，安装Python Graphviz，该路径将包含可执行文件。

Windows:

安装windows包从:https://graphviz.gitlab.io/_pages/Download/Download_windows.html 安装python graphviz包添加“用户路径”为“C:\Program Files (x86)\ Graphviz2.38\bin” 将C:\Program Files (x86)\ Graphviz2.38\bin\dot.exe添加到“系统路径”

这对我很管用!

步骤1:安装Graphviz二进制文件

窗口:

从http://www.graphviz.org/download/下载Graphviz 将以下内容添加到PATH环境变量(提到已安装的graphviz版本): C:\Program Files (x86)\ Graphviz2.38\bin C:\Program Files (x86)\ Graphviz2.38\bin\dot.exe 关闭任何打开的Juypter笔记本电脑和命令提示符重新启动Jupyter / cmd提示符并测试

Linux:

Sudo apt-get update Sudo apt-get安装graphviz 或者从http://www.graphviz.org/download/手动构建

步骤2:安装python的graphviz模块

皮普:

PIP安装graphviz

第二:

康达安装图形可视化

尝试conda install graphviz。我也遇到了同样的问题，我在MacOS中使用上述命令解决了它。
