Read more in the User Guide. I would like to use AgglomerativeClustering from sklearn but I am not able to import it. If we apply the single linkage criterion to our dummy data, say between Anne and cluster (Ben, Eric) it would be described as the picture below. @adrinjalali I wasn't able to make a gist, so my example breaks the length recommendations, but I edited the original comment to make a copy+paste example. Note also that when varying the I think the problem is that if you set n_clusters, the distances don't get evaluated. It must be None if distance_threshold is not None. 41 plt.xlabel("Number of points in node (or index of point if no parenthesis).") affinitystr or callable, default='euclidean' Metric used to compute the linkage. If True, will return the parameters for this estimator and contained subobjects that are estimators. Sign up for a free GitHub account to open an issue and contact its maintainers and the community.
