Getting COCO categories in the order in which it is trained

[ghost]

From the model zoo, I am using the Cascade Mask RCNN model pre-trained on MSCOCO. I would like to do model surgery for one of my applications. How can I find out the order of the COCO categories by which the pre-trained model was trained on MSCOCO? For instance, MaskRCNN-benchmark gives the order of the categories by which they trained Mask RCNN model here.

You can print the "thing_classes" metadata of a dataset using the example at https://detectron2.readthedocs.io/tutorials/datasets.html#metadata-for-datasets
