python - 我收到 : chart_studio. 异常。PlotlyRequestError:未提供身份验证凭据

Question

我在本地工作(在我的电脑上)只是测试和学习 PLOTLY 3.7.5。
anaconda env 处于事件状态。
代码示例由 plotly 给出

代码:

import plotly.plotly as py  # Here all begins (Look)
# import chart_studio.plotly as py  # inted of the line bellow (optional to  try)
import plotly.graph_objs as go
import pandas as pd
from datetime import datetime

if __name__ == '__main__':
    df = pd.read_csv('https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv')
    trace = go.Ohlc(x=df['Date'],
                    open=df['AAPL.Open'],
                    high=df['AAPL.High'],
                    low=df['AAPL.Low'],
                    close=df['AAPL.Close'])
    data = [trace]
    py.iplot(data, filename='simple_ohlc')

注意(看):我收到警告错误:

'please install the chart-studio package and use the chart_studio.plotly module instead.'

您需要 plotly 的离线模式来避免身份验证 - 关注 https://stackoverflow.com/a/44694854/1021819 ，而是做:

from plotly.offline import iplot
