I am trying to convert the keypoint float values into integers the json.dumps save the changes like i perform (del person['area']) but do not save the changes i applied on keypoint. in CLI of python it displays the keypoints as integer array but when i dumps it to new json file the changes are not don and save as the same original. Help appreciate

You have to reassign the keypoints in the given json after converting the data.

check below code:

for person in data['annotations']:
    key = person["keypoints"]
    person["keypoints"] = [math.trunc(k) for k in key]
