Description
def mapper(dataset_dict):
dataset_dict = copy.deepcopy(dataset_dict) # it will be modified by code below
image = utils.read_image(dataset_dict["file_name"], format="BGR")
transform_list = [
T.ResizeShortestEdge(short_edge_length=(640, 672, 704, 736, 768, 800), max_size=1333, sample_style='choice')
,T.RandomRotation([10,15])
]
image, transforms = T.apply_transform_gens(transform_list, image)
dataset_dict["image"] = torch.as_tensor(image.transpose(2, 0, 1).astype("float32"))
#print('image_shape->',image.shape,image.shape[:2])
annos = [
utils.transform_instance_annotations(obj, transforms, image.shape[:2])
for obj in dataset_dict.pop("annotations")
if obj.get("iscrowd", 0) == 0
]
instances = utils.annotations_to_instances(annos, image.shape[:2])
dataset_dict["instances"] = instances
#dataset_dict["instances"] = utils.filter_empty_instances(instances)
return dataset_dict
this is my mapper for augmentation.
is T.RandomRotation([10,15]) happen every image? or by some change.
if it apply to every images. how should I apply it by only some percentage?

Research direction
Start with the mapper shown in the issue and the documented behavior of T.RandomRotation. Check whether the transform is applied deterministically or probabilistically, and identify the documented way to configure a target application percentage; the issue names no repository file or test.
