Python: ‘SMOTE’ object has no attribute ‘_validate_data’ 如何解决???求大神

代码如下：

#过采样算法
import pandas as pd
from imblearn.over_sampling import SMOTE
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import confusion_matrix
from sklearn.model_selection import train_test_split

columns=data.columns
X_columns=columns.delete(len(columns)-1)
X=data.drop([‘target’],axis=1)
y=data[‘target’]
X_train,X_test,y_train,y_test=train_test_split(X,
y,
test_size=0.2,
random_state=0)

oversample=SMOTE(random_state=0)
X_os,y_os=oversample.fit_resample(X_train,y_train)

执行后:
AttributeError Traceback (most recent call last)

–> 134 X, y = self._validate_data(
135 X, y, reset=True, accept_sparse=accept_sparse
136 )
