python - Pandas 数据读取器引发 AttributeError : module 'pandas.io' has no attribute '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 ")

它给我以下错误。几天前，当我尝试相同的代码时没有出现错误。

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

我正在使用 Anaconda、Python 3.x。这是 Pandas 的问题还是我的系统有问题？

pandas 已删除该功能，现在作为不同的包提供 (link):

DataReader The sub-package pandas.io.data is removed in favor of a separately installable pandas-datareader package. This will allow the data modules to be independently updated to your pandas installation. The API for pandas-datareader v0.1.1 is the same as in pandas v0.16.1. (GH8961)

You should replace the imports of the following:

from pandas.io import data, wb

With the following:

from pandas_datareader import data, wb

安装 pandas_datareader使用 pip install pandas-datareader 并将代码替换为以下内容:

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))
