如何让gmaps热图显示在Jupyterlab？

Question

这是我使用过的代码，但我一直使用 Figure(layout=FigureLayout(height='420px'))作为输出。我如何得到实际的地图来显示

import gmaps

from config import gkey

gmaps.configure(api_key=gkey)

locations = file_df[["Latitude", "Longitude"]]
weight = file_df["Humidity"]

fig = gmaps.figure()

fig.add_layer(gmaps.heatmap_layer(locations, weights = weight, max_intensity = 100))
fig
