model = KMeans()

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

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

Answer 1

试试这个：

conda install -c districtdatalabs yellowbrick

Answer 2

您好，谢谢您查看Yellowbrick

sklearn v0.22中不推荐使用sklearn.metrics.classification模块，因此我们更新了包，改为从sklearn.metrics._classification导入

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

Answer 3

看起来您的yellowbrick没有正确安装。尝试仅为用户安装：

pip install -U yellowbrick
