Question

我正在尝试可视化网络节点的网络中心度和中间度

T是我的datacamp工作区中加载的网络（已经尝试将其加载到pycharm中）。

我以x轴为中间性中心，以y轴为度中心性。我想要得到的是标签-情节中每个点的节点号

# Compute the betweenness centrality of T: bet_cen
bet_cen = nx.betweenness_centrality(T)

# Compute the degree centrality of T: deg_cen
deg_cen = nx.degree_centrality(T)

n=list(T.nodes())

# Create a scatter plot of betweenness centrality and degree centrality
plt.scatter(list(bet_cen.values()),list(deg_cen.values()))

for i,txt in enumerate(n):
    plt.annotate(txt, (list(bet_cen.values()),list(deg_cen.values())))

# Display the plot
plt.show()

我收到此错误
