为什么我在把labelme提取的json文件转换为png时，会显示usage: labelme_json_to_dataset [-h] [-o OUT] json_file

import os

json_folder = r"G:\test 2\1"   #这个路径包含了图像和对应的json文件，就是上面截图的路径
#  获取文件夹内的文件名
FileNameList = os.listdir(json_folder)
#  激活labelme环境
os.system("activate ame=labelme")
for i in range(len(FileNameList)):
    #  判断当前文件是否为json文件
    if(os.path.splitext(FileNameList[i])[1] == ".json"):
        json_file = json_folder + "\\" + FileNameList[i]
        #  将该json文件转为png
        os.system("labelme_json_to_dataset " + json_file)
