Object Detection Quantization fails with OpenVINO 2024.3

[fmishra747]

🐛 Describe the bug

The yolov8 object detection quantization fails at
File /lib/python3.10/site-packages/ultralytics/models/yolo/detect/val.py", line 183, in get_stats

**self.nt_per_image = np.bincount(stats["target_img"].astype(int), minlength=self.nc)

KeyError: 'target_img'**

Environment

Yolov8 model with coco128 dataset Object Detection Quantization fails with
OpenVINO 2024.3,
"python_version": "3.10",
nncf 2.13.0.dev0+eb91af2d
ultralytics 8.2.74
ultralytics-thop 2.0.0
torch 2.4.0+cpu
torchvision 0.19.0+cpu

The same application works fine with
OpenVINO 2024.1
"python_version": "3.10",
ultralytics 8.2.18
nncf 2.11.0.dev0+24f0ee70
torch 2.2.2+cpu
torchvision 0.17.2+cpu

Minimal Reproducible Example

Execute object detection quantization python script after changing the extension from .md file
quantize_accuracy_aware_object_detection_fullyworking.py.md
with yolov8 and coco128 dataset
