Descrizione
clf = KNN(metric="cosine")
clf.fit(train_data)
results in
sklearn/neighbors/_binary_tree.pxi in sklearn.neighbors._ball_tree.BinaryTree.__init__()
sklearn/neighbors/_dist_metrics.pyx in sklearn.neighbors._dist_metrics.DistanceMetric.get_metric()
ValueError: Unrecognized metric 'cosine'
Also brute and kd_tree don't support cosine, meaning that cosine is not supported by any algorithm.
