我试图使用pygraphviz＆＃39;使用networkX进行点布局。但我收到了错误
File "C:\Users\msi\Anaconda3\lib\site-packages\pyparsing.py", line 1028, in preParse
while loc < instrlen and instring[loc] in wt:
TypeError: 'in <string>' requires string as left operand, not int
可能是因为graphviz不适用于我正在使用的python 3.
这是我的代码：
import networkx as nx
import matplotlib.pyplot as plt
G=nx.DiGraph()
n = [1,2,3,4,5,6,7,8,9,10,11,12,13,14]
e = [(1,2),(1,3),(2,4),(2,5),(3,6),(3,7),
(8,9),(8,10),(9,11),(9,12),(10,13),(10,14),(7,8)]
G.add_nodes_from(n)
G.add_edges_from(e)
pos=nx.graphviz_layout(G,prog='dot')
nx.draw(G, pos=pos, with_labels=True)
plt.show()
