1.       (Project: Predicting EMNIST Digits with a Pretrained MNIST Model)   For this exercise, load the digits subset of EMNIST, which contains 280,000 digit images. Load the MNIST convnet model you trained in this chapter then use it to evaluate the prediction accuracy for the EMNIST digits. How accurate is your model with EMNIST?

2.       (Project: Predicting MNIST Digits with a Pretrained EMNIST Model)   For this exercise, load Keras’s MNIST dataset and the EMNIST convnet model for both characters and digits you trained in Exercise 16.19. How accurate is your EMNIST model at predicting MNIST’s digits?
