为什么不能导入AgglomerativeClustering类?

我想使用 AgglomerativeClustering 来自sklearn，但我无法导入它.

I would like to use AgglomerativeClustering from sklearn but I am not able to import it.

Traceback (most recent call last):

推荐答案

查看版本0.15的更改日志，似乎在此版本中引入了AgglomerativeClustering类:

Looking at the changelog for version 0.15 it looks like the AgglomerativeClustering class was introduced in this version:

• 添加了cluster.AgglomerativeClustering用于具有平均链接，完全链接和 病房策略. [...]

• Added cluster.AgglomerativeClustering for hierarchical agglomerative clustering with average linkage, complete linkage and ward strategies. [...]

因此，唯一的解决方法是安装更新版本的sklearn.

So the only fix is to install a newer version of sklearn.
