Model builders
--------------

The following model builders can be used to instantiate a Mask R-CNN model, with or
without pre-trained weights. All the model builders internally rely on the
``torchvision.models.detection.mask_rcnn.MaskRCNN`` base class. Please refer to the `source
code
<https://github.com/pytorch/vision/blob/main/torchvision/models/detection/mask_rcnn.py>`_ for
more details about this class.
