PlotlyRequestError：未提供身份验证凭据python

问题描述

我正在尝试使用plotly进行一些可视化。但是，当我尝试进行可视化时，总是会遇到以下错误。

以下是我的代码。

#Boxplot and histogram of Total Direct Variable Cost grouped by with or with Financial Class
import chart_studio.plotly as py

from  plotly.offline import iplot
trace0 = go.Box(
    y=healthcare.loc[healthcare['A'] == 'Inpatient']['B'],name = 'Inpatient',marker = dict(
        color = 'rgb(214,12,140)',)
)
trace1 = go.Box(
    y=healthcare.loc[healthcare['A'] == 'InBorn']['B'],name = 'InBorn',marker = dict(
        color = 'rgb(0,128,128)',)
)
data = [trace0,trace1]
layout = go.Layout(
    title = "CCCCCCCCCCCC"
)

fig = go.figure(data=data,layout=layout)
py.iplot(fig)

解决方法

我遇到了同样的问题，所以我将py.iplot(fig)更改为fig.show()

阅读：https://plotly.com/python/troubleshooting/

对于 Jupyter 经典笔记本：

import plotly.io as pio
pio.renderers.default='notebook'

然后使用 fig.show() 如上所述。
