Pyvis Network中select_menu设置异常：开启后网络无法显示

修复方案 #

1. 关闭Notebook模式 #

notebook=True模式下，Pyvis生成的HTML适配Jupyter环境，但与select_menu功能存在兼容性冲突。将notebook参数设为False即可解决：

from pyvis.network import Network
import networkx as nx

G = nx.Graph()
rels = [
    ["Fred", "George"],
    ["Harry", "Rita"],
    ["Fred", "Ginny"],
    ["Tom", "Ginny"],
    ["Harry", "Ginny"],
    ["Harry", "George"],
    ["Frank", "Ginny"],
    ["Marge", "Rita"],
    ["Fred", "Rita"]
]
G.add_edges_from(rels)

# 关闭notebook模式，启用select_menu
net = Network(notebook=False, height="750px", width="100%", bgcolor='#222222', font_color='white', select_menu=True)
net.from_nx(G)
net.save_graph("networkx-pyvis.html")

生成HTML文件后，直接用浏览器打开就能看到正常显示的网络和节点选择菜单。

2. 升级Pyvis版本 #

旧版Pyvis存在select_menu功能的已知bug，执行以下命令升级到最新版：

pip install --upgrade pyvis
