LightningIRConfigClassFactory

class lightning_ir.base.class_factory.LightningIRConfigClassFactory(MixinConfig: Type[LightningIRConfig])[source]

Bases: LightningIRClassFactory

Class factory for creating derived LightningIRConfig classes from HuggingFace configuration classes.

__init__(MixinConfig: Type[LightningIRConfig]) → None

Creates a new LightningIRClassFactory.

Parameters:: MixinConfig (Type[LightningIRConfig]) – LightningIRConfig mixin class

Methods

`from_backbone_class`(BackboneClass)	Creates a derived LightningIRConfig from a transformers.PretrainedConfig backbone configuration class.
`from_pretrained`(model_name_or_path, *args, ...)	Loads a derived LightningIRConfig from a pretrained HuggingFace model.

Attributes

property cc_lir_model_type: str: Camel case model type of the Lightning IR model.

from_backbone_class(BackboneClass: Type[PretrainedConfig]) → Type[LightningIRConfig][source]

Creates a derived LightningIRConfig from a transformers.PretrainedConfig backbone configuration class. If the backbone configuration class is already a dervied LightningIRConfig, it is returned as is.

Parameters:: BackboneClass (Type[PretrainedConfig]) – Backbone configuration class
Returns:: Derived LightningIRConfig
Return type:: Type[LightningIRConfig]

from_pretrained(model_name_or_path: str | Path, *args, **kwargs) → Type[LightningIRConfig][source]

Loads a derived LightningIRConfig from a pretrained HuggingFace model.

Parameters:: model_name_or_path (str | Path) – Path to the model or its name
Returns:: Derived LightningIRConfig
Return type:: Type[LightningIRConfig]

static get_backbone_config(model_name_or_path: str | Path) → PretrainedConfig

Grabs the configuration from a checkpoint of a pretrained HuggingFace model.

Parameters:: model_name_or_path (str | Path) – Path to the model or its name
Returns:: Configuration of the backbone model
Return type:: PretrainedConfig

static get_backbone_model_type(model_name_or_path: str | Path, *args, **kwargs) → str

Grabs the model type from a checkpoint of a pretrained HuggingFace model.

Parameters:: model_name_or_path (str | Path) – Path to the model or its name
Returns:: Model type of the backbone model
Return type:: str

static get_lightning_ir_config(model_name_or_path: str | Path) → LightningIRConfig | None

Grabs the Lightning IR configuration from a checkpoint of a pretrained Lightning IR model.

Parameters:: model_name_or_path (str | Path) – Path to the model or its name
Returns:: Configuration class of the Lightning IR model
Return type:: LightningIRConfig | None

static get_lightning_ir_model_type(model_name_or_path: str | Path) → str | None

Grabs the Lightning IR model type from a checkpoint of a pretrained HuggingFace model.

Parameters:: model_name_or_path (str | Path) – Path to the model or its name
Returns:: Model type of the Lightning IR model
Return type:: str | None
