Question

当我运行这个例子时：

import networkx as nx
import matplotlib.pyplot as plt

B=[[0,1],
  [2,4],
  [5,6],
  [3,7],
  [0,3]]
G = nx.Graph()   
for i in range(len(B)):
    G.add_edge((B[i][0]),(B[i][1]))
nx.draw(G,with_labels=True, node_color=[0,1,1,0,0,1,1,0]) 
plt.show()

显示图表。但是，当我添加更多边和节点颜色时，如下所示：

import networkx as nx
import matplotlib.pyplot as plt

B=[[0,1],
  [2,4],
  [5,6],
  [3,7],
  [0,3],
  [2,8],
  [7,11],
  [6,10],
  [3,12],
  [6,12]]   
G = nx.Graph()   
for i in range(len(B)):
    G.add_edge((B[i][0]),(B[i][1]))

nx.draw(G,with_labels=True, node_color=[0,1,1,0,0,1,1,0,1,0,1,1,1]) 
plt.show()

它引发了这个错误。

ValueError: to_rgba: Invalid rgba arg "0"
to_rgb: Invalid rgb arg "0"
cannot convert argument to rgb sequence

我该如何解决这个问题？

Answer 1

The error didn't seem instructive to the nature of the problem here, but it's simply that you have 12 nodes and 13 node colours. Remove one of the items in [0,1,1,0,0,1,1,0,1,0,1,1,1] and the problem goes away.
