§Note

This optimizer is memory intensive

Implementations§

Source§

impl<B: Backend + AutodiffBackend> LBFGS<B>

Source

pub fn to_record(&self) -> LBFGSState<B::InnerBackend>

Export the optimizer state for checkpointing.

Source

pub fn load_record(self, record: LBFGSState<B::InnerBackend>) -> Self

Source

pub fn step<M, F>( &mut self, lr: LearningRate, module: M, closure: F, ) -> (M, f64)
where M: AutodiffModule<B> + Clone, F: FnMut(M) -> (f64, GradientsParams),

A single optimization step for any tensor that represents the parameters of a model.

Source

pub fn to_device(self, device: &B::Device) -> Self
