Plotly hover_数据不适用于dict？

Question

如plotly docs中所述，可以通过将键设置为列、将值设置为布尔值来传递dict，以便管理显示的内容和未显示的内容或格式：

hover_data = {"killed":True,"group":True,"lat":False,"long":False,"year":False}

fig = px.scatter_mapbox(df_clean, lat="lat", lon="long", hover_name="hover_title",
                        animation_frame="year",
                        color_discrete_sequence=["red"],
                        opacity = 1,
                        zoom=1, size="killed",
                        hover_data=hover_data)

这就产生了

RuntimeError: dictionary changed size during iteration

我错过了什么？ 我看到有人在绘声绘色的上下文中使用dict（{…}），但我看不出它是如何工作的，也看不到它的帮助
