Cannot use my predicted files to run the inference.py

[Tz2H]

I replace the cfg load_prediction_file in test_submission.yml to my prediction file using YOLOv8 and it's in the KITTI format. But when I run the CLI python inference.py --cfg "../configs/KITTI_inference:test_submission.yml" I receive a error like:
'''
Traceback (most recent call last):
File "inference.py", line 288, in
main()
File "inference.py", line 278, in main
generate_empty_file(output_dir, test_calib_dir)
File "inference.py", line 207, in generate_empty_file
detected = os.listdir(os.path.join(output_dir, 'data'))
FileNotFoundError: [Errno 2] No such file or directory: '../MyOutput/submission/data'
'''

My folder structure is the same with provided folder and the name of .txt file is the same too.
I don't know what causes this error, please give me some advice!
