问题描述
我无法在Windows 7上运行Python的pydot.
I'm having trouble running Python's pydot on Windows 7.
我使用以下命令安装了pydot:conda install -c rmg pydot=1.2.2
I installed pydot with: conda install -c rmg pydot=1.2.2
我在../Program Files (x86)/Graphviz2.38/
运行以下脚本时,出现错误提示
When I run the following script I get an error saying
"dot.exe" not found in path
import pydot
graph = pydot.Dot(graph_type='digraph')
node_a = pydot.Node("Node A", style="filled", fillcolor="red")
node_b = pydot.Node("Node B", style="filled", fillcolor="green")
node_c = pydot.Node("Node C", style="filled", fillcolor="#0000ff")
node_d = pydot.Node("Node D", style="filled", fillcolor="#976856")
graph.add_node(node_a)
graph.add_node(node_b)
graph.add_node(node_c)
graph.add_node(node_d)
graph.add_edge(pydot.Edge(node_a, node_b))
graph.add_edge(pydot.Edge(node_b, node_c))
graph.add_edge(pydot.Edge(node_c, node_d))
graph.add_edge(pydot.Edge(node_d, node_a, label="and back we go again", labelfontcolor="#009933", fontsize="10.0", color="blue"))
graph.write_png('example2_graph.png')
Exception: "dot.exe" not found in path.
我已经尝试过以下解决方案: ../Graphiv2.38/bin/
文件所在的../Graphiv2.38/bin/
.但是我仍然会收到错误消息.
I have tried this solution: Permanently adding a file path to sys.path in Python, by adding the my-paths.pth
file with a line pointing to../Graphiv2.38/bin/
where the dot.exe
file is located. But I still get the error.
我还能尝试什么?
推荐答案
我按照此博客.
然后我从此处安装了graphviz,并添加了C:\ Program Files(x86)\ Graphviz2. 38 \ bin到PATH
.
Then I installed graphviz from here and added C:\Program Files (x86)\Graphviz2.38\bin to PATH
.
接下来我做了:
conda install pydot-ng
最后,在笔记本中,我在下面添加了两行.
And finally in my notebook I added the two lines below.
import os
os.environ["PATH"] += os.pathsep + 'C:/Program Files (x86)/Graphviz2.38/bin/'
这篇关于"dot.exe"在路径中找不到. Python(Windows 7)上的Pydot的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
