Yolo8 to coreml conversion

[dhiman10]

from ultralytics import YOLO

model=YOLO('runs/detect/train/weights/best.pt')

model.export(format='coreml',nms=True)

CoreML: export failure ❌ 9.9s: 1 name found for nc=8395 CoreML model is not converted.

I have found this error when I use nms=True, I need the model with bounding box. Could you help me ?
