labelme 修改后的json文件 ，imageData 值改为null的脚本

import os

import json

def set_image_data_to_null(directory):

for filename in os.listdir(directory):

if filename.endswith('.json'):

file_path = os.path.join(directory, filename)

with open(file_path, 'r', encoding='utf-8') as file:

data = json.load(file)

将 imageData 设置为 None，在JSON文件中会显示为 null

if 'imageData' in data:

data['imageData'] = None

保存修改后的文件

with open(file_path, 'w', encoding='utf-8') as file:

json.dump(data, file, indent=4)

替换以下路径为你的JSON文件所在的文件夹路径

directory_path = 'path_to_your_directory'

set_image_data_to_null(directory_path)
