python-3.x - ModuleNotFoundError : No module named 'imblearn'

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)

这给了我错误信息:

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(安装过程中未出现任何错误，但是当我运行上述代码时，出现错误消息)。

我使用其他stackoverflow问题中建议的以下内容尝试了istalling imblearn:

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

这些似乎都无济于事...有什么想法吗？谢谢!

最佳答案

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

同样，我尝试通过pip安装imblearn，它对我有用。

(base) C:\WINDOWS\system32>pip install -U imbalanced-learn
