我得到：chart_studio.exceptions.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 处于活动状态。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：

'请安装 chart-studio 包并改用 chart_studio.plotly 模块。

Answer 1

您需要 plotly 的离线模式来避免身份验证 - 遵循/sf/answers/3128639811/，而不是这样做：

from plotly.offline import iplot

Answer 2

自动调用下面这两个库问题就解决了

import chart_studio.plotly as py
