RandomUnderSampler'对象没有属性'fit_resample' [英] RandomUnderSampler' object has no attribute 'fit_resample'

问题描述

我正在使用imblearn中的RandomUnderSampler，但是出现以下错误.有任何想法吗?谢谢

I am using RandomUnderSampler from imblearn, but I get the following error. Any ideas? Thanks

from imblearn.under_sampling import RandomUnderSampler
print('Initial dataset shape %s' % Counter(y.values.squeeze()))
rus = RandomUnderSampler(random_state=42)
X_undersampled, y_undersampled = rus.fit_resample(X, y)
y_undersampled = y_undersampled.squeeze()

输出:

Initial dataset shape Counter({0: 2499739, 1: 1558})

      2 rus = RandomUnderSampler(random_state=42)
----> 3 X_undersampled, y_undersampled = rus.fit_resample(X, y)
      4 y_undersampled = y_undersampled.squeeze()

AttributeError: 'RandomUnderSampler' object has no attribute 'fit_resample'

我正在使用的主要库:

imbalanced-learn==0.3.3
pandas==0.24.2
numpy==1.15.4
scikit-learn==0.19.2

推荐答案

方法fit_resample最近被引入到imbalanced-learn API中.更新imbalanced-learn或改用fit_sample.

The method fit_resample was introduced lately to imbalanced-learn API. Either update imbalanced-learn or use fit_sample instead.
