The KNN accuracy code has a small error. Please replace
Scholar.Metrics.confusion_matrix(test_targets, test_preds, num_classes: 3)
with
Scholar.Metrics.Classification.confusion_matrix(test_targets, test_preds, num_classes: 3)

(edit)
In addition, on page 114, please replace
Scholar.Metrics.accuracy(test_targets, test_preds)
with
Scholar.Metrics.Classification.accuracy(test_targets, test_preds)
