使用 web.DataReader、yahoo finance 加载数据时出错

Question

我尝试使用 web.DataReader 加载数据，但我总是收到错误“RemoteDataError：无法读取 URL： https://finance.yahoo.com/quote/FB/history?period1=1325390400&period2=1577937599&=interval=1d&frequencyhist&=interval=1d&frequencyhist “ 。

我已经使用了以下 package 更新，昨天我的代码运行良好。 但是今天我仍然遇到与以前相同的错误（即无法读取 URL）。

!pip install --upgrade pandas
!pip install --upgrade pandas-datareader

PS：我使用谷歌 Colab

这是我的代码的完整开头（包括错误）：

!pib install numpy
!pib install matplotlib
!pib install pandas
!pip install --upgrade pandas
!pip install --upgrade pandas-datareader

 # Importing packages
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
import pandas_datareader as web
import datetime as dt
from sklearn.preprocessing import MinMaxScaler #package used in order to scale the data
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Dense, Dropout, LSTM

# Load Data 
company = 'FB' #picking the company we want to study

start=dt.datetime(2012,1,1) # picking the dataframe we are interested in 
end=dt.datetime(2020,1,1)

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

() ----> 1 data = web.DataReader(company, 'yahoo',start,end) 中的 RemoteDataError Traceback（最后一次调用）

如果有人面临与我相同的问题，我只是找到了解决方法！

在你的笔记本中修改这段代码：

start=dt.datetime(2010,1,1)
end=dt.datetime(2017,1,1)
df = yf.download(tickers=['^GSPC'], start=start, end=end)
