TypeError: scatter() got an unexpected keyword argument 'trendline_options' (Plotly, Python)

Question

我遇到错误：

TypeError: scatter() got an unexpected keyword argument 'trendline_options'

尝试使用 plotly express 调整最低趋势线的平滑度时。

这是我的图形代码：

fig = px.scatter(dfg, x="Yr_Mnth", y="Episode_Count", color = "Target",
                        labels={"Episode_Count": tally + " per Shift",
                                "Target":"Target",
                                "Yr_Mnth": "Date" },
                        trendline='lowess',trendline_options= dict(frac=0.1), title="Aggregate Behavior Data: " + patient + " - " + today)
        fig.update_xaxes(tickangle=45,)
        fig.update_layout(template = 'plotly_white',hovermode="x unified")

数据集（dfg）：

Yr_Mnth                         Target              Episode_Count

我觉得这很奇怪，因为我直接按照文档操作 - https://plotly.com/python/linear-fits/

这是一个已知问题吗？我无法通过 google 搜索找到任何示例...
