MOTCUSTOM evaluation

[Hunter-v1]

I m evaluating my yolo model and reid model with strongsort! I have my own dataset (10 drone classes)!
MOTCUSTOM contains same architecture described here https://github.com/mikel-brostrom/yolov8_tracking/wiki/How-to-evaluate-on-custom-tracking-dataset but it keeps generating
dict_keys([])
Traceback (most recent call last):
File "/content/yolov8_tracking/val.py", line 358, in
e.run(opt)
File "/content/yolov8_tracking/val.py", line 305, in run
print('HOTA:', combined_results['HOTA'])
KeyError: 'HOTA'
please help as soon as possible
