Я пытаюсь получить доступ к библиотеке цен на акции с помощью виртуальной машины Google, однако у меня сложилось впечатление, что она слишком мощная. Когда я делаю свой запрос, он отправляет его:

Aquí está mi códi go, puse un sleep en el medio para regular el tiempo de votación. 

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from yahooquery import Ticker
#import scipy.optimize as scoplt.style.use('fivethirtyeight')
np.random.seed(777)
def price_maker(tickers):
    df_concated = pd.DataFrame()
    for ticker_name in tickers:
        sleep(0.5)
        ticker = Ticker(ticker_name)
        df = ticker.history(period='max', interval='1d', start='2016-01-04', end='2020-08-05')
        try:
            df_concated = pd.concat([df_concated, df['close'].rename(str(ticker_name))], axis=1)
        except KeyError:
            print("ticker_name: ", ticker_name)
    return df_concated

def main():
    df_red = pd.read_csv('C:/Users/antoi/Documents/Programming/portfolio-advisor/dashboard/data/tickers_september_2017_red.csv')
    tickers = df_red['Ticker'].values
    df = price_maker(tickers)

if __name__ == '__main__':
    main()

Тем не менее, он хорошо работает, когда я запускаю его локально. Что вы думаете? Думаю, это потому, что моя виртуальная машина слишком быстрая.
