TypeError: scatter()获得意外的关键字参数'trendline_options‘(Plotly，Python)

Question

我得到了错误：

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

当尝试使用plotly express调整低的肌腱线的平滑度时。

下面是我的图表代码：

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，因为我直接跟在文档后面-- https://plotly.com/python/linear-fits/

这是一个已知的问题吗？我在谷歌上找不到任何例子...

正如Henry很有帮助地指出的那样，这只是一个版本问题，很容易通过使用以下命令进行更新来解决：

pip install plotly==5.2.1
