title: How to calculate Silhouette Score of the scipy's fcluster using scikit-learn silhouette score?
body: <p>I am using scipy.cluster.hierarchy.linkage as a clustering algorithm and pass the result linkage matrix to <a href="http://docs.scipy.org/doc/scipy/reference/generated/scipy.cluster.hierarchy.fcluster.html" rel="noreferrer">scipy.cluster.hierarchy.fcluster</a>, to get the flattened clusters, for various thresholds. </p>
  
  <p>I would like to calculate the Silhouette score of the results and compare them to choose the best threshold and prefer not to implement it on my own but use scikit-learn's <a href="http://scikit-learn.org/stable/modules/generated/sklearn.metrics.silhouette_score.html" rel="noreferrer">sklearn.metrics.silhouette_score</a>. 
  How can I rearrange my clustering results as an input to sklearn.metrics.silhouette_score?</p>
