When load the nuscenes-GROUNDTRUTH-trainsplit-trackresults.json file, I met the following error:

json.decoder.JSONDecodeError: Expecting value: line 1 column 24908261 (char 24908260)

The file appears to be corrupted. Following is the tail content:

Another 2 questions:

  1. how did you generate the GROUNDTRUTH file for train/val splits? Is these needed in preprocessing?
  2. Should DetectionBox in this line be TrackingBox? Otherwise, how did you get the trakcing GT infomation.

    SpOT/preprocessing/nuscenes/preprocess.py

    Line 66 in bb5566c

    self.gt_boxes = load_gt_local(self.nusc, self.split, DetectionBox, verbose=True)
