pandas_datareader 中的 NotImplementedError

Question

我試圖從 Yahoo Finance 讀取數據，但出現錯誤。

這是我的代碼：

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import pandas_datareader as data

這是我收到錯誤的單元格：

start = '2012-01-01' 
end = '2021-12-31'

df = data.DataReader('AAPL', start, end)

這是我遇到的錯誤消息：

---------------------------------------------------------------------------
NotImplementedError                       Traceback (most recent call last)
<ipython-input-12-d022432a6feb> in <module>()
      2 end = '2021-12-31'
      3 
----> 4 df = data.DataReader('AAPL', start, end)

    371     if data_source not in expected_source:
    372         msg = "data_source=%r is not implemented" % data_source
--> 373         raise NotImplementedError(msg)
    374 
    375     if data_source == "yahoo":

NotImplementedError: data_source='2012-01-01' is not implemented

任何幫助將不勝感激。 謝謝：）

df = data.DataReader('AAPL', 'yahoo', start = '2012-01-01', end = '2021-12-31')
