pygraphviz

问题 I am trying to install pygraphviz on Windows 10. There are many solutions to this problem online, but none have yet worked for me. The precise problem I\'m having is with this via jupyter notebook--> [1] import networkx as nx import pylab as plt from networkx.drawing.nx_agraph import graphviz_layout [2]G = nx.DiGraph() G.add_node(1,level=1) G.add_node(2,level=2) G.add_node(3,level=2) G.add_node(4,level=3) G.add_edge(1,2) G.add_edge(1,3) G.add_edge(2,4) nx.draw(G, pos=graphviz_layout(G), node

问题 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.
