Why does python fail when loading data set ".load_data()"

Question

here is my code

import tensorflow as tf
from tensorflow import keras
import numpy as np
import matplotlib.pyplot as plt

data = keras.datasets.fashion_mnist

(train_images, train_labels), (test_images, test_labels) = data.load_data()

and it is giving me this long scary error:

Downloading data from https://storage.googleapis.com/tensorflow/tf-keras-datasets/train-labels-idx1-ubyte.gz

I am really new to this so am really lost...

This may be because you don't have python certificates installed, which is a pretty common error on Macs. You should be able to solve it by going into wherever you have Python installed and install your certificates by double clicking on your "Install Certificates.command" file.
