DeviceStatsMonitor

class pytorch_lightning.callbacks.DeviceStatsMonitor(cpu_stats=None)[source]

Bases: pytorch_lightning.callbacks.callback.Callback

Automatically monitors and logs device stats during training, validation and testing stage. DeviceStatsMonitor is a special callback as it requires a logger to passed as argument to the Trainer.

Parameters

cpu_stats (Optional[bool]) – if None, it will log CPU stats only if the accelerator is CPU. It will raise a warning if psutil is not installed till v1.9.0. If True, it will log CPU stats regardless of the accelerator, and it will raise an exception if psutil is not installed. If False, it will not log CPU stats regardless of the accelerator.

Raises

MisconfigurationException – If Trainer has no logger.

Example

>>> from pytorch_lightning import Trainer
>>> from pytorch_lightning.callbacks import DeviceStatsMonitor
>>> device_stats = DeviceStatsMonitor() 
>>> trainer = Trainer(callbacks=[device_stats]) 
on_test_batch_end(trainer, pl_module, outputs, batch, batch_idx, dataloader_idx)[source]

Called when the test batch ends.

Return type

None

on_test_batch_start(trainer, pl_module, batch, batch_idx, dataloader_idx)[source]

Called when the test batch begins.

Return type

None

on_train_batch_end(trainer, pl_module, outputs, batch, batch_idx)[source]

Called when the train batch ends.

Note

The value outputs["loss"] here will be the normalized value w.r.t accumulate_grad_batches of the loss returned from training_step.

Return type

None

on_train_batch_start(trainer, pl_module, batch, batch_idx)[source]

Called when the train batch begins.

Return type

None

on_validation_batch_end(trainer, pl_module, outputs, batch, batch_idx, dataloader_idx)[source]

Called when the validation batch ends.

Return type

None

on_validation_batch_start(trainer, pl_module, batch, batch_idx, dataloader_idx)[source]

Called when the validation batch begins.

Return type

None

setup(trainer, pl_module, stage)[source]

Called when fit, validate, test, predict, or tune begins.

Return type

None
