Python 无法使用我的代码获取Choropleth地图：请引导，谢谢

我收到这个错误：choropleth方法已被弃用。而是使用具有相同参数的新Choropleth类。请参阅示例笔记本“GeoJSON_和_choropleth”，了解如何做到这一点

with open('C:/Users/abcdef/Desktop/world_countries.json') as data_file:
    data = json.load(data_file)

world_geo = data
world_map = folium.Map(location=[0, 0], zoom_start=2, tiles = 'Mapbox Bright')
world_map.choropleth(
    geo_data = world_geo,
    data = canadamap,
    columns = ['Country', 'Total'],
    key_on = 'feature.properties.name',
    fill_color = 'YlOrRd', 
    fill_opacity = 0.7, 
    line_opacity = 0.2,
    legend_name = 'Immigration to Canada'
)

world_map

我没有使用上面的代码获得Choropleth地图；相反，我得到了

这应该对你有用。该方法已修改为Choropleth而非Choropleth。 你应该

folium.Choropleth(args*).add_to(world_map) 

总共

world_geo = r'world_countries.json' # geojson file

    # create a plain world map
world_map = folium.Map(location=[0, 0], zoom_start=2, tiles='Mapbox Bright')

# generate choropleth map using the total immigration of each country to Canada from 1980 to 2013
folium.Choropleth(
    geo_data=world_geo,
    data=df_can,
    columns=['Country', 'Total'],
    key_on='feature.properties.name',
    fill_color='YlOrRd', 
    fill_opacity=0.7, 
    line_opacity=0.2,
    legend_name='Immigration to Canada'
).add_to(world_map)

# display map

    world_map

我希望这对你有所帮助

这条信息告诉你你需要知道的一切。您需要使用

Choropleth

类，因为该方法不再受支持。您需要阅读文档，以了解这将如何改变执行。
