我目前正在分割Json档案。
JSON文件的结构如下：
{
"id": 2131424,
"file": "video_2131424_1938263.mp4",
"metadata": {
"width": 3840,
"height": 2160,
"duration": 312.83,
"fps": 30,
"frames": 9385,
"created": "Sun Jan 17 17:48:52 2021"
},
"frames": [
{
"number": 207,
"image": "frame_207.jpg",
"annotations": [
{
"label": {
"x": 730,
"y": 130,
"width": 62,
"height": 152
},
"category": {
"code": "child",
"attributes": [
{
"code": "global_id",
"value": "7148"
}
]
}
},
{
"label": {
"x": 815,
"y": 81,
"width": 106,
"height": 197
},
"category": {
"code": "person",
"attributes": []
}
}
]
},
{
"number": 221,
"image": "frame_221.jpg",
"annotations": [
{
"label": {
"x": 730,
"y": 130,
"width": 64,
"height": 160
},
"category": {
"code": "child",
"attributes": [
{
"code": "global_id",
"value": "7148"
}
]
}
},
{
"label": {
"x": 819,
"y": 82,
"width": 106,
"height": 200
},
"category": {
"code": "person",
"attributes": []
}
}
]
},
{
"number": 236,
"image": "frame_236.jpg",
"annotations": [
{
"label": {
"x": 731,
"y": 135,
"width": 74,
"height": 160
},
"category": {
"code": "child",
"attributes": [
{
"code": "global_id",
"value": "7148"
}
]
}
},
{
"label": {
"x": 821,
"y": 83,
"width": 106,
"height": 206
},
"category": {
"code": "person",
"attributes": []
}
}
]
},我必须从每个标签中提取[x，y，width，height]。我尝试了如下代码：
file = json.load(open('annotation_2131424.json'))
file['frames'][i]['annotations'][j]['label']['x']但是我不能拆分JSON。我试过这样做，但是我不能运行...

我希望我没理解错你的问题，要从每个
label中得到x、y、width、height（dct是你的问题字典）：印刷品：
