pandas datareader引发AttributeError：模块'pandas.io'没有属性'data'

Question

这是我正在尝试的代码

import matplotlib.pyplot as plt    
import pandas as pd
ticker = 'GLD'
begdate = '2014-11-11'
enddate = '2016-11-11'
data1 = pd.io.data.DataReader(ticker,'yahoo',dt.datetime(2014,11,11),dt.datetime(2016,11,11))
gld_df = pd.DataFrame(data1)
date_df = pd.to_datetime(list(gld_df.index))
adj_close_df = list(gld_df["Adj Close"])
plt.plot(date_df,adj_close_df)
plt.title("SPDR Gold Shares ")

它给了我下面的错误。几天前，当我尝试相同的代码时没有错误。

runfile('D:/Quant/MSQF/4 - Algorithms 1/3-Sorting/Mini Project 2_v2.py', wdir='D:/Quant/MSQF/4 - Algorithms 1/3-Sorting')

    data1 = pd.io.data.DataReader(ticker,'yahoo',dt.datetime(2014,11,11),dt.datetime(2016,11,11))

AttributeError: module 'pandas.io' has no attribute 'data'

我正在使用Anaconda，Python 3.x。这是熊猫问题还是我的系统问题？

Answer 1

pandas删除了该功能，现在将其作为其他软件包提供（link）：

DataReader删除了子软件包pandas.io.data，转而使用了可单独安装的pandas-
datareader软件包。这将允许将数据模块独立更新到您的pandas安装。pandas-datareader v0.1.1的API与pandas
v0.16.1中的API相同。（GH8961）

您应该替换以下内容的导入：

from pandas.io import data, wb

具有以下内容：

from pandas_datareader import data, wb

安装pandas_datareader与pip install pandas-datareader
并替换为以下代码：

from pandas_datareader import data
import datetime as dt
ticker = 'GLD'
begdate = '2014-11-11'
enddate = '2016-11-11'
data1 = data.DataReader(ticker,'yahoo',dt.datetime(2014,11,11),dt.datetime(2016,11,11))
