- class paddlespeech.text.models.ernie_linear.ernie_linear_updater.ErnieLinearUpdater(model: Layer, criterion: Layer, scheduler: LRScheduler, optimizer: Optimizer, dataloader: DataLoader, output_dir=None)[source]
Bases:
StandardUpdater
- Attributes:
updates_per_epoch
Number of updater per epoch, determined by the length of the dataloader.
Methods
new_epoch
()Start a new epoch.
read_batch
()Read a batch from the data loader, auto renew when data is exhausted.
set_state_dict
(state_dict)Set state dict for a Updater.
state_dict
()State dict of a Updater, model, optimizer and updater state are included.
update_core
(batch)A simple case for a training step.
load

update
- update_core(batch)[source]
A simple case for a training step. Basic assumptions are: Single model; Single optimizer; A batch from the dataloader is just the input of the model; The model return a single loss, or a dict containing serval losses. Parameters updates at every batch, no gradient accumulation.
