Python中的Yellowbrick模块NotFoundError

问题描述

我正在尝试使用Yellowbrick绘制肘部曲线(以使k均值聚类)

I am trying to using Yellowbrick to make an elbow plot.(to make the k-means clustering)

我已在jupyter笔记本中安装了Yellowbrick.但是，它会继续返回错误消息，如下所示.

I have installed Yellowbrick in jupyter notebook. but, it keeps returning the error message like below.

错误消息和信息如下图所示.如果您能帮助我，我将非常高兴.

The error message and information are attached as pictures below.I would be very happy if you could help me.

from yellowbrick.cluster import KElbowVisualizer

model = KMeans()

visualizer = KElbowVisualizer(model, k=(1,250))

visualizer.fit(x.reshape(-1,1))

推荐答案

您好，感谢您检查Yellowbrick！

Hello and thanks for checking out Yellowbrick!

在sklearn v0.22中已弃用了sklearn.metrics.classification模块，因此我们更新了程序包以从sklearn.metrics._classification导入.

The sklearn.metrics.classification module was deprecated in sklearn v0.22, so we have updated our package to import from sklearn.metrics._classification instead.

尝试更新scikit-learn的版本(例如pip install -U scikit-learn或conda update scikit-learn)，看看是否有帮助！

Try updating your version of scikit-learn (e.g. pip install -U scikit-learn or conda update scikit-learn) and see if that helps!
