我正在关注这个例子（https://github.com/geodocker/geodocker-jupyter-geopyspark/blob/master/notebooks/sanfranmvp.ipynb）所以我可以复制类似的输出，除了最后一个之外，每个都是成功的，我已经尝试了所有可能的调整但没有成功，请有人帮忙告诉我我做错了什么。这是代码的最后一步，使用 folium 在 Jupyter notebook 中查看我的地图。

m = folium.Map(tiles='OpenStreetMap', location=map_center, zoom_start=zoom)

folium.TileLayer(tiles=tms.url_pattern, attr='GeoPySpark', name='Weighted layer', overlay=True).add_to(m)

folium.GeoJson('data/bars.geojson', name='Bars', style_function=lambda x: {'radius': 2, 'color': 'red'}, overlay=True).add_to(m)

folium.GeoJson('data/cafes.geojson', name='Cafes', style_function=lambda x: {'fillColor': 'orange'}, overlay=True).add_to(m)

folium.GeoJson('data/transit.geojson', name='Transit', style_function=lambda x: {'fillColor': 'green'}, overlay=True).add_to(m)

m

这是错误消息：

这是我对该问题的最终解决方案，在@ottomeister 的帮助下，我能够缩小我的研究范围，从而找到解决方案。

m = folium.Map(tiles='OpenStreetMap', location=map_center, zoom_start=zoom)
folium.TileLayer(tiles=tms.url_pattern, attr='MYGeoPySpark', name='Weighted layer', overlay=True).add_to(m)
folium.GeoJson(json.load(open('data/bars.geojson', encoding = 'utf-8')), name='Bars', style_function=lambda x: {'radius': 2, 'color': 'red'}, overlay=True).add_to(m)
folium.GeoJson(json.load(open('data/cafes.geojson', encoding = 'utf-8')), name='Cafes', style_function=lambda x: {'fillColor': 'orange'}, overlay=True).add_to(m)
folium.GeoJson(json.load(open('data/transit.geojson', encoding = 'utf-8')), name='Transit', style_function=lambda x: {'fillColor': 'green'}, overlay=True).add_to(m)

m
