How to take just the IoU mean

[greg007-web]

With this code:

from detectron2.evaluation import COCOEvaluator, inference_on_dataset
from detectron2.data import DatasetCatalog, MetadataCatalog, build_detection_test_loader

class CocoTrainer(DefaultTrainer):
  
  @classmethod
  def build_evaluator(cls, cfg, dataset_name, output_folder=None):

    if output_folder is None:
        os.makedirs("coco_eval", exist_ok=True)
        output_folder = "coco_eval"

    return COCOEvaluator(dataset_name, cfg, False, output_folder)
    

I take mAP inforation that uses IoU results.:

But I want jut the mean of IoU. How I do this on detectron2 using google colab.
