pydot

I'm having trouble running Python's pydot on Windows 7. I installed pydot with: conda install -c rmg pydot=1.2.2 I have graphviz installed under ../Program Files (x86)/Graphviz2.38/ 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

I am trying to make a few interactive graph visualisations in my Django web application using Python. I found Graphviz and was able to output a static graph (as a .png image) on my application using Pydot (Python interface to Graphviz's dot language). However, I am looking to make my graphs more interactive, like being able to highlight nodes when passing my mouse over it, making the nodes click-able, dragging the nodes to a different location and zooming on the graph. Is there a way I could do this in Graphviz? Or in general is there way to make an interactive graph for my Django application

Off the bat - Ubuntu 12.04, python 2.7, using pydot 1.0.2 I'm trying to get pydot to print a tree to a .png. I'm making my nodes like so: subnode = pydot.Node(fullstr, label = c + "\n" + n) graph.add_node(subnode) Here, c and n and fullstr are just strings. This is fine but when I run: graph.write_png(output_path) I get the following error (yikes!) - stay tuned after the break Traceback (most recent call last): File "Ant.py", line 47, in <module> f.makeOutput("output/ant", display=True) File "/home/aespielberg/ppr/ppr/svggen/library/api/component.py", line 322, in makeOutput self

I have a dictionary object as such: menu = {'dinner':{'chicken':'good','beef':'average','vegetarian':{'tofu':'good','salad':{'caeser':'bad','italian':'average'}},'pork':'bad'}} I'm trying to create a graph (decision tree) using pydot with the 'menu' data this . 'Dinner' would be the top node and its values (chicken, beef, etc.) are below it. Referring to the link, the graph function takes two parameters; a source and a node. It would look something like this : Except 'king' would be 'dinner' and 'lord' would be 'chicken', 'beef', etc. My question is: How do I access a key in a value? To create

I want to plot a decision tree of a random forest. So, i create the following code: clf = RandomForestClassifier(n_estimators=100) import pydotplus import six from sklearn import tree dotfile = six.StringIO() i_tree = 0 for tree_in_forest in clf.estimators_: if (i_tree <1): tree.export_graphviz(tree_in_forest, out_file=dotfile) pydotplus.graph_from_dot_data(dotfile.getvalue()).write_png('dtree'+ str(i_tree) +'.png') i_tree = i_tree + 1 But it doesn't generate anything.. Have you an idea how to plot a decision tree from random forest ? Thank you, Assuming your Random Forest model is already

I'm using Anaconda Python 2.7 on windows 10 I was planning on doing Keras visualization so (whilst spyder was open) I opened the Anaconda command prompt and pip installed graphviz and pydot. Now when I try run the following: from keras.models import Sequential or any sort of "from keras." , I get the error: ImportError: cannot import name gof I have uninstalled and reinstalled Keras, Graphviz and pydot. i am using the development version of theano. I cannot find a fix. P.S If I uninstall graphviz and pydot, keras works again EDIT After uninstalling anaconda and reinstalling it including theano
