Bases: tlc.core.schema.Schema

A Schema defining an (x, y, z) value

class tlc.core.builtins.schemas.schemas.COCOLabelSchema(display_name: str = 'label', description: str = 'COCO Label', writable: bool = False, display_importance: float = 0)

Bases: tlc.core.schema.Schema

A Schema defining COCO label

class tlc.core.builtins.schemas.schemas.CIFAR10LabelSchema(display_name: str = 'label', description: str = 'CIFAR-10 Label', writable: bool = False, display_importance: float = 0, value_type: str = _DEFAULT_SCALAR_VALUE_TYPE)

Bases: tlc.core.schema.Schema

A Schema defining CIFAR10 label

class tlc.core.builtins.schemas.schemas.CategoricalLabelSchema(class_names: list[str], display_name: str = 'label', description: str = '', writable: bool = False, display_colors: list[str] | None = None, display_importance: float = 0)

Bases: tlc.core.schema.Schema

A schema for a categorical label

class tlc.core.builtins.schemas.schemas.FloatVector2Schema(display_name: str = '2D Embedding', description: str = '', writable: bool = False, display_importance: float = 0, number_role: str = NUMBER_ROLE_XY_COMPONENT)

Bases: tlc.core.schema.Schema

A schema for a 2D vector

class tlc.core.builtins.schemas.schemas.FloatVector3Schema(display_name: str = '3D Embedding', description: str = '', writable: bool = False, display_importance: float = 0, number_role: str = NUMBER_ROLE_XYZ_COMPONENT)

Bases: tlc.core.schema.Schema

A schema for a 3D vector

Bases: tlc.core.schema.Schema

A schema for example ID values

Example ID is a unique identifier for an example. It is used to identify examples across different tables.

class tlc.core.builtins.schemas.schemas.EpochSchema(display_name: str = 'Epoch', description: str = 'Epoch of training', display_importance: float | None = None)

Bases: tlc.core.schema.Schema

A schema for epoch values

class tlc.core.builtins.schemas.schemas.IterationSchema(display_name: str = 'Iteration', description: str = 'The current iteration of the training process.', display_importance: float | None = None)

Bases: tlc.core.schema.Schema

A schema for iteration values

class tlc.core.builtins.schemas.schemas.ForeignTableIdSchema(foreign_table_url: str, display_name: str = '')

Bases: tlc.core.schema.Schema

A schema describing a value that identifies a foreign table

class tlc.core.builtins.schemas.schemas.SampleWeightSchema(display_name: str = 'Weight', description: str = 'The weights of the samples in this table.', sample_type: str = 'hidden', default_value: float = 1.0)

Bases: tlc.core.schema.Schema

A schema for sample weight values

Initialize the SampleWeightSchema

Parameters:

• display_name – The display name of the schema

• description – The description of the schema

• sample_type – The sample type of the schema

• default_value – The default value of the schema
