This check only works on the Object Detection task. .. GENERATED FROM PYTHON SOURCE LINES 28-39 Generate Dataset ================ We generate a sample dataset of 128 images from the `COCO dataset `__, and using the `YOLOv5 model `__. .. note:: In this example, we use the pytorch version of the coco dataset and model.

GENERATED FROM PYTHON SOURCE LINES 62-67 Observe the check’s output -------------------------- The result value is a dataframe that has the Mean Average Precision score for different bounding box area sizes. We report the mAP for different IoU thresholds: 0.5, 0.75 and an average of mAP values for IoU thresholds between 0.5 and 0.9 (with a jump size of 0.05). ..
