问题描述

我试图显示树的输出，但是当我运行下面的脚本时，出现如下错误:

I am trying to display the tree output , but when I run the script below, I receive an error like :

InvocationException:找不到GraphViz的可执行文件

InvocationException: GraphViz's executables not found

我在这里搜索了类似的主题，但是其中大多数与Mac相关.我使用的是Windows 10 64位操作系统，而我使用的是Anaconda-3 64位.我很想听听您对此的建议.

I've searched similar topics here, but most of them are Mac related. I'm using Windows 10 64-bit operating system, and I use Anaconda-3 64 bit. I'd love to hear your suggestions on this.

#Displaying the decision tree
from sklearn import tree
#from StringIO import StringIO
from io import StringIO
#from StringIO import StringIO 
from IPython.display import Image
out = StringIO()
tree.export_graphviz(classifier, out_file=out)

import pydotplus
graph=pydotplus.graph_from_dot_data(out.getvalue())
Image(graph.create_png())

edit:我再次安装了graphviz和pydotplus模块，但现在仍然可以使用.

edit : I've installed graphviz and pydotplus modules again, but still now working.
