Helpers for detectron2
DummyAlbuMapper allows you to use albumentations during fitting detectron2 for detection tasks.
It requires improvements to work with keypoints and masks.
To use custom dataset_mapper you also need to define new class Trainer with modified build_train_loader.
Smth like this:
from detectron2.engine import DefaultTrainer
class Trainer(DefaultTrainer):
@classmethod
def build_train_loader(cls, cfg):
mapper = DummyAlbuMapper(cfg, is_train=True)
return build_detection_train_loader(cfg, mapper=mapper)
