无法从“sklearn.metrics”导入名称“mean\u absolute\u percentage\u error”

Question

我收到一条错误消息：

cannot import name 'mean_absolute_percentage_error' from 'sklearn.metrics'

，当我运行以下程序包时：

我很感激你对我的建议。多谢各位

您需要从forge channel安装最新版本的scikit-learn：

conda install -c conda-forge scikit-learn 

为了检查您的安装，您可以使用

conda list scikit-learn  # to see which scikit-learn version is 
installedconda list  # to see all packages installed in the active conda 
environmentpython -c "import sklearn; sklearn.show_versions()"
