Thank you for publicizing such an excellent piece of work, when I was trying to reproduce your code, I got the following error： ----------------------------------------AP40 evaluation---------------------------------------- ------------------evalute model: output-------------------- ********************car******************** Traceback (most recent call last): File "lib/train_val.py", line 138, in <module> main_worker(args.local_rank,args.nprocs, args) # (0, 0, args) File "lib/train_val.py", line 97, in main_worker tester.test() File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\helpers\tester_helper.py", line 77, in test Car_res = eval.do_repo3d_eval( File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 1352, in do_repo3d_eval eval_from_scrach(logger,label_dir,filter_dir,eval_cls,ap_mode=40) File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 1336, in eval_from_scrach res = get_official_eval_result(all_gt, all_det, cls, z_axis=1, z_center=1) File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 1126, in get_official_eval_result metrics = do_eval_v3( File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 1023, in do_eval_v3 ret = eval_class_v3( File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 844, in eval_class_v3 rets = calculate_iou_partly( File "C:\Users\cqx\Desktop\traffic_3d_detection\lib\eval_tools\eval.py", line 726, in calculate_iou_partly gt_boxes = np.concatenate([a["bbox"] for a in gt_annos_part], 0) File "<__array_function__ internals>", line 200, in concatenate ValueError: need at least one array to concatenate
I don't know what's wrong, I hope I can get your help, thank you very much!
