I see this too, just missing Classification on p106

Scholar.Metrics.Classification.accuracy(test_targets, test_preds)

Similarly on p107 with confusion_matrix/3, it is also missing the Classification:

Scholar.Metrics.Classification.confusion_matrix(test_targets, test_preds, num_classes: 3

p110

Scholar.Metrics.Classification.accuracy(test_targets, test_preds)
Scholar.Metrics.Classification.confusion_matrix(test_targets, test_preds, num_classes: 3
