torchsig.transforms.metadata_transforms.YOLOLabel

class torchsig.transforms.metadata_transforms.YOLOLabel(**kwargs)[source]

Bases: MetadataTransform

Adds a YOLO_label to a signal.

This transform adds a YOLO_label to a signal in the form of a list of tuples (cid, cx, cy, width, height).

required_metadata

List of metadata fields required for applying the transform.

targets_metadata

List of metadata fields that will be added by the transform.

Methods

add_parent

Add parent Seedable object and set up RNGs accordingly.

get_distribution

Create distribution function with proper seeding.

get_second_seed

Gets second seed, usually used to seed both torch and numpy generators with slightly different seeds.

seed

Seed number generators with given seed.

setup_rngs

Initialize torch and numpy number generators, and update its children.

update_from_parent

Update numpy and torch number generators with parent seed.

__init__(**kwargs)[source]

Initialize the YOLOLabel transform.

Parameters:

**kwargs – Additional keyword arguments passed to the parent class.

__call__(signal: Signal) Signal

Applies the target transform to a list of signal metadata.

Parameters:

signal – The signal to transform.

Returns:

The transformed signal.

__repr__() str

Returns a detailed string representation of the transform object.

Returns:

A string representation of the transform object.

__str__() str

String representation of the transform.

Returns:

String representation of the transform.

add_parent(parent: Seedable, register: bool = True) None

Add parent Seedable object and set up RNGs accordingly.

Parameters:
  • parent – Parent Seedable object to add.

  • register – If True (default), add self to parent.children so that future seed propagation reaches this object. Pass False for transient objects (e.g. per-sample Signal instances) that only need the parent link for metadata/RNG access during their lifetime but must not accumulate in the parent’s child list, which would otherwise cause unbounded memory growth.

get_distribution(params: list | tuple | float, scaling: str = 'linear') Distribution

Create distribution function with proper seeding.

Parameters:
  • params – Parameters for distribution.

  • scaling – Scaling param for distribution. Defaults to ‘linear’.

Returns:

Distribution function, seeded.

Return type:

Distribution

get_second_seed(seed: int) int

Gets second seed, usually used to seed both torch and numpy generators with slightly different seeds.

Parameters:

seed – Seed to use.

Returns:

New seed.

seed(seed: int) None

Seed number generators with given seed.

Parameters:

seed – Seed to use.

setup_rngs() None

Initialize torch and numpy number generators, and update its children.

update_from_parent() None

Update numpy and torch number generators with parent seed.
