python 判断两个集合相等

import os
import cv2

if __name__ == '__main__':
    img_path=r'/home/cui/tianrui_projects/darknet53/code_data/raw_data/images/'
    label_path=r'/home/cui/tianrui_projects/darknet53/code_data/raw_data/labels/'

    #保证数据一致性
    all_imgs=set(map(lambda p:p.split('.')[0],os.listdir(img_path)))
    all_labels=set(map(lambda p:p.split('.')[0],os.listdir(label_path)))
    print(all_imgs.issubset(all_labels) and all_labels.issubset(all_imgs))
