mlx.nn.Module.apply#

Module.apply(map_fn: Callable[[array], array], filter_fn: Callable[[Module, str, Any], bool] | None = None) → Module#

Map all the parameters using the provided map_fn and immediately update the module with the mapped parameters.

For instance running model.apply(lambda x: x.astype(mx.float16)) casts all parameters to 16 bit floats.

Parameters:

  • map_fn (Callable) – Maps an array to another array

  • filter_fn (Callable, optional) – Filter to select which arrays to map (default: Module.valid_parameter_filter()).

Returns:

The module instance after updating the parameters.
