Hi experts,
When running the C1W3 Lab 1, 2nd codes cell:
mnist = tf.keras.datasets.mnist
(x_train, y_train),(x_test, y_test) = mnist.load_data()
x_train, x_test = x_train / 255.0, x_test / 255.0
caused errors:

Have tried re-opened the notebook but same error when executing same codes cell.
Any idea what needs fixing?
Thanks,
