Я пытаюсь получить данные 50 компаний в Nifty50. 

import bs4 as bs
import datetime as dt
import os
import pandas as pd
import pandas_datareader.data as web
import pickle
import requests
def save_nifty50_tickers():
     resp=requests.get('https://en.wikipedia.org/wiki/NIFTY_50')
     soup = bs.BeautifulSoup(resp.text,'lxml')
     table = soup.find('table', {'class':'wikitable sortable'})
     tickers=[]
     for row in table.findAll('tr')[1:]:
         ticker=row.findAll('td')[0].text
         tickers.append(ticker)

     with open("nifty50tickers.pickle", "wb") as f:
             pickle.dump(tickers, f)

     print(tickers)
     return tickers
#save_nifty50_tickers()
def get_data_from_yahoo(reload_nifty50= False):
    if reload_nifty50:
        tickers = save_nifty50_tickers()

    else:
        with open("nifty50tickers.pickle", "rb") as f:
            tickers = pickle.load(f)
    if not os.path.exists('stock_dfs'):
        os.makedirs('stock_dfs')
    start = dt.datetime(2000,1,1)
    end =dt.datetime(2020,2,29)

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

ошибка, которую я получаю,
