python - 为什么弯曲的边缘在 networkx 中对我不起作用？

Question

所以我想要有弯曲的边缘，根据文档，它似乎超级容易，因为我可以定义connectionstyle. 所以我试图建立一个像这样的最小示例：

import numpy as np
import networkx as nx
import matplotlib.pyplot as plt

B = np.random.rand(5, 5)
G = nx.DiGraph(B)
A = nx.minimum_spanning_arborescence(G) # creating some arborescence, i.e. a directed graph

pos = nx.spring_layout(A)
nx.draw_networkx_nodes(A, pos, node_size=300)
nx.draw_networkx_edges(A, pos, connectionstyle='arc3, rad=0.2')
