'EventTypeClassificationPrepare' object has no attribute '_merge_ee_and_re_datas'

[TinaGioro]

在data_processing 部分，event_prepare_data.py的main函数的最后一句 train_data_list, train_label_list, train_token_type_id_list, dev_data_list, dev_label_list, dev_token_type_id_list = data_loader._merge_ee_and_re_datas( train_file, eval_file, "relation_extraction/data/train_data.json", "relation_extraction/data/dev_data.json") 但是，data_loader所属类EventTypeClassificationPrepare没有_merge_ee_and_re_datas这个方法，请问是代码没有贴上去吗？
