C1_W2_Lab_1_beyond_hello_world.ipynb: some portions still tailored for mnist dataset

In the exploration exercises some portions are still pertaining to mnist, instead of fashion_mnist.

  • mnist = tf.keras.datasets.mnist -> mnist = tf.keras.datasets.fashion_mnist
    • Exercises 2, 4, 5, and 7: no impact on the global meaning, just for consistency
    • Exercise 3: the dimensions in the error message don't match the explanation
    • Exercise 6: just might have an issue with the 128-neuron hidden layer not having the same behavior as the baseline 512-neuron layer in terms of loss evolution
  • Exercise 8, the 95% in the text should be changed to 60% (95% was for mnist)


  1. Hi! Thank you for the feedback! The end-of-lab exercises have now been revised to use fashion_mnist.
