Я продолжаю получать Python Исключение Сертификата Tensorflow

Question

Я новичок в python и в настоящее время учусь использовать Tensorflow. Я использую pycharm на MacOsX Catalina. Я использую видеоурок, чтобы узнать, как его использовать. Вот видео (включая отметку времени) . Вот код, который я запускаю:

import tensorflow as tf
from tensorflow import keras
import numpy as np
data = keras.datasets.imdb
data.load_data()

Кажется, это нормально; Я загружаю набор данных из библиотеки keras.datasets. Однако я постоянно сталкиваюсь с этой ошибкой:

Я действительно понятия не имею, что делать. Я запустил код установки сертификата, но он все еще не работает. Все помогает. Спасибо!
