Checks the PyTorch Automatic Mixed Precision (AMP) functionality of a YOLOv8 model. If the checks fail, it means
Checks the PyTorch Automatic Mixed Precision (AMP) functionality of a YOLO11 model. If the checks fail, it means
there are anomalies with AMP on the system that may cause NaN losses or zero-mAP results, so AMP will be disabled
during training.
Args:
model (nn.Module): A YOLOv8 model instance.
model (nn.Module): A YOLO11 model instance.
Example:
```python
from ultralytics import YOLO
from ultralytics.utils.checks import check_amp
model = YOLO("yolov8n.pt").model.cuda()
model = YOLO("yolo11n.pt").model.cuda()
check_amp(model)
```
Returns:
(bool): Returns True if the AMP functionality works correctly with YOLOv8 model, else False.
(bool): Returns True if the AMP functionality works correctly with YOLO11 model, else False.
