C = config.Config()

從get_data中獲取了圖片、類別計數(shù)、類別映射:

all_imgs, classes_count, class_mapping = get_data()

C.class_mapping = class_mapping

從all_imgs中獲取訓(xùn)練集、驗證集和測試集的圖片：
train_imgs = [s for s in all_imgs if s['imageset'] == 'trainval']

val_imgs = [s for s in all_imgs if s['imageset'] == 'test']
