AttributeError: ‘RandomOverSampler’ object has no attribute ‘fit_sample’

报错代码

resample_ratio = 0.3 # (anomalies / normal) after resampling
sample_normal = tn + fp # total number of true normal points
sample_anomaly = int(resample_ratio*sample_normal) # must be an integer
sampling_dict = {0: sample_normal, 1: sample_anomaly}
ros = RandomOverSampler(sampling_dict, random_state=0) 
features_resampled, label_resampled = ros.fit_sample(features,label)
