class_docstr: Base class for configuring :class:`DetectionEvaluation` instances.
  
  Args:
      pred_field: the name of the field containing the predicted
          :class:`fiftyone.core.labels.Detections`,
          :class:`fiftyone.core.labels.Polylines`, or
          :class:`fiftyone.core.labels.Keypoints`
      gt_field: the name of the field containing the ground truth
          :class:`fiftyone.core.labels.Detections`,
          :class:`fiftyone.core.labels.Polylines`, or
          :class:`fiftyone.core.labels.Keypoints`
      iou (None): the IoU threshold to use to determine matches
      classwise (None): whether to only match objects with the same class
          label (True) or allow matches between classes (False)
