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

Question

I try to load data using web.DataReader but I always get the error "RemoteDataError: Unable to read URL: https://finance.yahoo.com/quote/FB/history?period1=1325390400&period2=1577937599&interval=1d&frequency=1d&filter=history" .

I already used the following package updates and my code worked fine yesterday. However today I still get the same error as before (ie, unable to read URL).

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

PS: I use Google Colab

Here is the full beginning of my code (including the error):

!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)

If anyone faces the same issue as mine, I just found out how to solve it!

Adapt this piece of code in your notebook:

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