我正在尝试在我的 jupyter 笔记本中导入 SMOTE。我尝试了以下步骤；

我首先在终端中使用以下命令安装了 imblearn

conda install -c glemaitre imbalanced-learn

然后我使用以下命令在我的笔记本中导入 imblearn；

from imblearn import under_sampling, over_sampling

我收到以下错误；

谁能指导我？谢谢！

因此，在我使用以下步骤安装 SMOTE 后它起作用了；

pip install -U imbalanced-learn
conda install -c conda-forge imbalanced-learn

看起来我安装不正确。

我无法理解以前安装中的错误。如果有人能向我指出这些错误，我将不胜感激。

谢谢！
