ModuleNotFoundError: No module named 'ultralytics.nn.modules.conv'; 'ultralytics.nn.modules' is not a package

When retrained your model yolov8l.pt with custom dataset and then used best. pt for prediction it giving following errors:
ModuleNotFoundError: No module named 'ultralytics.nn.modules.conv'; 'ultralytics.nn.modules' is not a package
!python predict.py model=yolov8l.pt source="output_video.mp4" show=True

Same problem, has anyone solved it yet?

[WindyHu001]

same problem too.

[hjdasioh]

Did someone take it？

[FEIAFR11]

How can I solve it?

[TanXi789]

You'll have to retrain in yolov8-deepsosrt to get best.pt files
