Labelling in kitti

Hello, I would like to know what software or program would you recommend me to make the labeling in kitti to allow us to replicate (or approach) the models generated by you.

Thanks.

Actually it is not a difficult job to generate KITTI format label files.
Reference: Is it possible to generate .tfrecorfs for tlt training directly without using intermediate kitti format? - #2 by Morganh
