helloall this is my first post.
I am currently halfway through a Udemy course titled "Build and train a data model to recognize objects in images!" (https://www.udemy.com/course/pythondatascience/) and am having difficulty with one of the tasks (running on a 2019 MacBook Pro with 10.15.6, using PyCharm IDE).
The task requires to run the code below to open/render an image from the CiFAR10 dataset:
from PIL import Image
labels = ['airplane', 'automobile', 'bird', 'cat', 'deer', 'dog', 'frog', 'horse', 'ship', 'truck']
from keras.datasets import cifar10
# X_train = images, y_train = labels
(X_train, y_train), (X_test, y_test) = cifar10.load_data()
index = 5
display_image = X_train[index]
display_label = y_train[index][0]
from matplotlib import pyplot as plt
final_image = plt.imshow(display_image)
final_image.show()
However I get the following errors and do not know what to do. I have posted on the course but being 3 years old, I don’t think anyone is keeping up to date with it and am not getting and responses.

The only information I have found mentions that I might have an unstable internet connection, but that is not the case.
With some of the posts I notice that their run terminal says "Using TensorFlow backend" however mine does not say this, it only says "Downloading data from https://www.cs.toronto.edu/~kriz/cifar-10-python.tar.gz"
Please help. Thank you
