Bases: noether.core.callbacks.periodic.PeriodicCallback

Callback to log the learning rate of the optimizer.

Initializes the PeriodicCallback.

Parameters:

  • callback_config (noether.core.schemas.callbacks.CallBackBaseConfig) – Configuration of the PeriodicCallback. Implements the CallBackBaseConfig schema.

  • trainer (noether.training.trainers.BaseTrainer) – Trainer of the current run, subclass of SgdTrainer.

  • model (noether.core.models.ModelBase) – Model of the current run.

  • data_container (noether.data.container.DataContainer) – DataContainer instance that provides access to all datasets.

  • tracker (noether.core.trackers.BaseTracker) – Tracker instance to log metrics to stdout/disk/online platform.

  • log_writer (noether.core.writers.LogWriter) – LogWriter instance to log metrics.

  • checkpoint_writer (noether.core.writers.CheckpointWriter) – CheckpointWriter instance to save checkpoints.

  • metric_property_provider (noether.core.providers.MetricPropertyProvider) – MetricPropertyProvider instance to access properties of metrics.

  • name (str | None) – Name of the callback.

should_log_after_update(training_iteration)

Checks after every update if the PeriodicCallback should be invoked.

Parameters:

training_iteration (noether.core.utils.training.training_iteration.TrainingIteration) – TrainingIteration to check.
