Расшифровка ответов разных кодировок

Я пытаюсь получить данные о тике из всех списков в S & P 500 из программирования python для учебных пособий по финансам (ссылка). К сожалению, при запуске моего кода появляется следующая ошибка:

requests.exceptions.ContentDecodingError: ('Received response with 
content-encoding: gzip, but failed to decode it.', error('Error -3 while
decompressing data: incorrect data check',))

Я предполагаю, что эта проблема исходит из разных кодировок для разных запасов. Как я могу изменить свой код (показано ниже), чтобы разрешить декодирование gzip?

import bs4 as bs
import pickle
import requests
import datetime as dt
import os
import pandas as pd
import pandas_datareader.data as web

def save_sp500_tickers():
response = requests.get('https://en.wikipedia.org/wiki/List_of_S%26P_500_companies')
#retrieve src code from url

soup = bs.BeautifulSoup(response.text, 'lxml')
#convert src code into bs4 format

table = soup.find('table', {'class':'wikitable sortable'})
#search the new soup object for the table tag of class wikitable sortable

tickers = []
#create a target array

for row in table.findAll('tr')[1:]:
#for each row in table find all rows sliced from index1
    ticker = row.findAll('td')[0].text
    #find all tableDefinitions and convert to text
    tickers.append(ticker)
    #add ticker to our tickers array
with open("sp500tickers.pickle","wb") as f:
    pickle.dump(tickers, f)

print(tickers)

return tickers

def getDataFromYahoo(reload_sp500 = False):
if(reload_sp500):
    tickers = save_sp500_tickers()
else:
    with open("sp500tickers.pickle","rb") as f:
        tickers = pickle.load(f)

if not os.path.exists('stock_dfs'):
    os.makedirs('stock_dfs')

start = dt.datetime(2010,1,1)
end = dt.datetime(2018,7,26)

for ticker in tickers:
    print(ticker)
    if not os.path.exists('stocks_dfs/{}.csv'.format(ticker)):
        df = web.DataReader(ticker, 'yahoo', start, end)
    else:
        print('Already have {}'.format(ticker))

getDataFromYahoo()
