无法使用Cluster_Ensembles库

Question

为了执行集成集群，我尝试使用Cluster_Ensembles，对于初学者，我使用页面上提到的代码，也在下面提到。

import numpy as np
import Cluster_Ensembles as CE
cluster_runs = np.random.randint(0, 50, (50, 15000))
consensus_clustering_labels = CE.cluster_ensembles(cluster_runs, verbose = True, N_clusters_max = 50)

它给了我以下错误：

INFO: Cluster_Ensembles: cluster_ensembles: due to a rather large number of cells in your data-set, using only 'HyperGraph Partitioning Algorithm' (HGPA) and 'Meta-CLustering Algorithm' (MCLA) as ensemble consensus functions.

NameError: name 'reduce' is not defined

如果我遗漏了什么或者如何处理这个错误，请指导我。

由于以下链接处理错误NameError: name 'reduce' is not defined，因此您可能会发现它们很有帮助：

• Cluster_Ensembles#Issue17

• Cluster_Ensembles#PullRequest18

总而言之，您的问题将通过以下命令来解决：

pip install -U git+https://github.com/mvr320/Cluster_Ensembles
