python - Pandas_DataReader 不适用于 Yahoo Finance API

问题描述

一个月前，我开始研究一个项目，尝试使用历史数据预测未来的股票价格。项目进展顺利，我决定稍作休息来升级我的电脑。好吧，我在完成计算机后尝试检查我的代码，但现在我遇到了一堆关于从 Yahoo Finance API 提取数据的错误。我的朋友正在做同一个项目，他说他在代码中没有遇到任何问题，所以我认为我的代码环境有问题。我不知道该怎么做，因为我对编码很陌生，但我希望有人可以帮助我处理下面的代码部分：

import pandas_datareader as web
import datetime as dt

# Load Data

symbols = 'NIO'

start = dt.datetime(2012,1,1)
end = dt.datetime(2020,1,1)

data = web.DataReader(symbols, 'yahoo', start, end)

这是我得到的错误代码：

RemoteDataError                           Traceback (most recent call last)

     18 
---> 19 data = web.DataReader(symbols, 'yahoo', start, end)
