JAX

model_navigator.api.jax

JAX optimize API.

optimize(model, model_params, dataloader, sample_count=DEFAULT_SAMPLE_COUNT, batching=True, target_formats=None, runners=None, profiler_config=None, workspace=None, verbose=False, debug=False, verify_func=None, custom_configs=None)

Function exports JAX model to all supported formats.

Parameters:

Name	Type	Description	Default
model	Callable	JAX forward function	required
model_params	Any	JAX model parameters (weights)	required
dataloader	SizedDataLoader	Sized iterable with data that will be feed to the model	required
sample_count	int	Limits how many samples will be used from dataloader	DEFAULT_SAMPLE_COUNT
batching	Optional[bool]	Enable or disable batching on first (index 0) dimension of the model	True
target_formats	Optional[Union[Union[str, Format], Tuple[Union[str, Format], ...]]]	Target model formats for optimize process	None
runners	Optional[Union[Union[str, Type[NavigatorRunner]], Tuple[Union[str, Type[NavigatorRunner]], ...]]]	Use only runners provided as paramter	None
profiler_config	Optional[ProfilerConfig]	Profiling config	None
workspace	Optional[Path]	Workspace where packages will be extracted	None
verbose	bool	Enable verbose logging	False
debug	bool	Enable debug logging from commands	False
verify_func	Optional[VerifyFunction]	Function for additional model verifcation	None
custom_configs	Optional[Sequence[CustomConfig]]	Sequence of CustomConfigs used to control produced artifacts	None

Returns:

Type	Description
Package	Package descriptor representing created package.
