oat]`): A list of thresholds used to stratify predictions into levels. labels (`list[int`): A list of values to label predictions belonging at each level. A label can be one of {-1, 0, 1} signifying {ignore, negative class, positive class}, respectively. allow_low_quality_matches (`bool`, *optional*, defaults to `False`): If `True`, produce additional matches for predictions with maximum match quality lower than high_threshold. See `set_low_quality_matches_` for more details. For example, thresholds = [0.3, 0.5] labels = [0, -1, 1] All predictions with iou < 0.3 will be marked with 0 and thus will be considered as false positives while training. All predictions with 0.3 <= iou < 0.5 will be marked with -1 and thus will be ignored. All predictions with 0.5 <= iou will be marked with 1 and thus will be considered as true positives. Nr
