pydot

My code is follow the class of machine learning of google.The two code are same.I don't know why it show error.May be the type of variable is error.But google's code is same to me.Who has ever had this problem? This is error [0 1 2] [0 1 2] Traceback (most recent call last): File "/media/joyce/oreo/python/machine_learn/VisualizingADecisionTree.py", line 34, in <module> graph.write_pdf("iris.pdf") AttributeError: 'list' object has no attribute 'write_pdf' [Finished in 0.4s with exit code 1] [shell_cmd: python -u "/media/joyce/oreo/python/machine_learn/VisualizingADecisionTree.py"] [dir: /media

I am running Python3.4 on Windows 7. I am trying to use the Python interface for graphviz. This is a script I intend to run: from graphviz import Digraph import pydotplus dot = Digraph(comment='The Round Table') dot.node('A', 'King Arthur') dot.node('B', 'Sir Bedevere the Wise') dot.node('L', 'Sir Lancelot the Brave') dot.edges(['AB', 'AL']) dot.edge('B', 'L', constraint='false') print(dot.source) dot.render('test-output/round-table.gv', view=True) I get the following error at runtime: RuntimeError: failed to execute ['dot', '-Tpdf', '-O', 'test-output/round-table.gv'], make sure the Graphviz

Trying to generate some PDF's of decision trees by following some of the sklearn documentation , but can't get Pydot on my machine. Is there any way to use the conda installer to install the pydot package? Based on the command line errors I'm seeing, it may be a 64bit issue. I use binstar search to find the package channel: C:\binstar search -t conda Which gives the recommendation of looking at the packages in detail using binstar show j14r/pydot Which then tells me to conda install --channel https://conda.binstar.org/j14r pydot But when I run the conda install command, I get the following

When I run a very simple code with pydot import pydot graph = pydot.Dot(graph_type='graph') for i in range(3): edge = pydot.Edge("king", "lord%d" % i) graph.add_edge(edge) vassal_num = 0 for i in range(3): for j in range(2): edge = pydot.Edge("lord%d" % i, "vassal%d" % vassal_num) graph.add_edge(edge) vassal_num += 1 graph.write_png('example1_graph.png') It prints me the error message: Couldn't import dot_parser, loading of dot files will not be possible. I'm using python 2.7.3 Jonathan Answer for pydot >= 1.1 : The incompatibility of (upstream) pydot has been fixed by 6dff94b3f1 , and thus

I have GraphViz 2.32 installed in Windows 8 and have added C:\Program Files (x86)\Graphviz2.32\bin to the System PATH variable. Still pydot is unable to find its executables.
