python - 模块未找到错误: No module named 'imblearn'

Question

我尝试运行以下代码:

from imblearn import under_sampling, over_sampling
from imblearn.over_sampling import SMOTE

sm = SMOTE(random_state=12, ratio = 1.0)
x_SMOTE, y_SMOTE = sm.fit_sample(X, y) 

这给了我错误消息:

ModuleNotFoundError: No module named 'imblearn'

我尝试以多种方式安装 imblearn 模块，它们似乎都可以工作(安装过程中没有给出错误，但当我运行上面的代码时，我收到一条错误消息)。

我尝试使用其他 stackoverflow 问题中建议的以下内容来安装 imblearn:

pip install -U imbalanced-learn
pip install imblearn
!pip install imblearn
pip install -c glemaitre imbalanced-learn
pip install imblearn==0.0

这些似乎都没有帮助......有什么想法吗？谢谢!

Answer 1

我使用 anaconda 命令提示符安装了名为 imblearn 的模块。

conda install -c conda-forge imbalanced-learn

然后导入包

from imblearn import under_sampling, over_sampling
from imblearn.over_sampling import SMOTE

我再次尝试通过 pip 安装 imblearn，它对我有用。
