删除实例分割中的特定标签

import json import os # 要处理的json文件夹路径 folder_path = 'H:/json' # 需要删除的标签列表,填写自己的标签 labels_to_remove = ['0', '1', '2', '3'] # 遍历文件夹中的所有文件 for filename in os.listdir(folder_path): if filename.endswith('.json'): file_path = os.path.join(folder_path, filename) # 读取JSON文件 with open(file_path, 'r') as file: data = json.load(file) # 遍历并删除特定标签的标注 data['shapes'] = [annotation for annotation in data['shapes'] if annotation['label'] not in labels_to_remove] # 保存修改后的JSON文件 with open(file_path, 'w') as file: json.dump(data, file, indent=4)
