如何在jupyter中使用交互式海运调色板？

pip install ipywidgets
pip install ipyleaflet

from ipywidgets import interact
from ipyleaflet import Map, basemaps, basemap_to_tiles, TileLayer, ColorPickerControl

m = Map(center=(0, 0), zoom=2)

color_picker = ColorPickerControl()
m.add_control(color_picker)

def update_map_color(change):
    m.background_color = change['new']

color_picker.observe(update_map_color, 'value')

m

from ipywidgets import interact
from ipyleaflet import Map, basemaps, basemap_to_tiles, TileLayer, ColorPickerControl

# 创建地图对象
m = Map(center=(0, 0), zoom=2)

# 创建颜色选择器控件
color_picker = ColorPickerControl()

# 添加颜色选择器到地图上
m.add_control(color_picker)

# 定义回调函数
def update_map_color(change):
    m.background_color = change['new']

# 连接回调函数
color_picker.observe(update_map_color, 'value')

# 显示地图
m
