ModuleNotFoundError：没有名为“ imblearn”的模块

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taltaling 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！

Answer 1

我安装了imblearn使用 anaconda 命令提示符命名的模块。

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

再次，我尝试imblearn通过 pip安装，它对我有用。

(base) C:\WINDOWS\system32>pip install -U imbalanced-learn
Requirement already up-to-date: imbalanced-learn in c:\users\ashok\anaconda3\lib\site-packages (0.4.3)
Requirement already satisfied, skipping upgrade: numpy>=1.8.2 in c:\users\ashok\anaconda3\lib\site-packages (from imbalanced-learn) (1.15.3)

Answer 2

在 AWS SageMaker 上，请按照文档操作：

!pip install imbalanced-learn

在笔记本单元中。

Answer 3

这对我有用

1. 首先在您的环境中安装该软件包：

pip install -U imbalanced-learn

2. 下一个：

conda install -c conda-forge imbalanced-learn

Answer 4

尝试这样：

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

或者

import imblearn *
