DistanceMetric class was moved from sklearn.neighbors to sklearn.metrics

Import DistanceMetric from sklearn.metrics

from sklearn.metrics import DistanceMetric

Change code to:

from sklearn.metrics import silhouette_score, adjusted_mutual_info_score, adjusted_rand_score, calinski_harabasz_score, davies_bouldin_score from sklearn.metrics import DistanceMetric # Import from sklearn.metrics instead from sklearn.decomposition import PCA from sklearn.cluster import KMeans from sklearn.manifold import TSNE from sklearn import preprocessing
