python - IpyLeaflet 未显示在 Jupyter 笔记本上

Question

我正在使用来自Ipyleaflet的一些文档代码

from ipyleaflet import Map, basemaps, basemap_to_tiles

m = Map(
    basemap=basemap_to_tiles(basemaps.NASAGIBS.ModisTerraTrueColorCR, "2017-04-08"),
    center=(52.204793, 360.121558),
    zoom=4
)

m

它仍然没有显示。我都试过了https://ipyleaflet.readthedocs.io/en/latest/installation.html

我机器的一些设置：Python 3.8.5 pip 21.3 from /Users/cmougan/opt/anaconda3/lib/python3.8/site-packages/pip (python 3.8)
