GPUAccelerator¶

class pytorch_lightning.accelerators.GPUAccelerator(precision_plugin, training_type_plugin)[source]¶

Bases: pytorch_lightning.accelerators.accelerator.Accelerator

Accelerator for GPU devices.

Parameters

precision_plugin¶ (PrecisionPlugin) – the plugin to handle precision-specific parts
training_type_plugin¶ (TrainingTypePlugin) – the plugin to handle different training routines

on_train_start()[source]¶

Called when train begins.

Return type: None

setup(trainer, model)[source]¶

Raises: MisconfigurationException – If the selected device is not GPU.
Return type: None

setup_environment()[source]¶

Setup any processes or distributed connections. This is called before the LightningModule/DataModule setup hook which allows the user to access the accelerator environment before setup is complete.

Return type: None

teardown()[source]¶

This method is called to teardown the training process. It is the right place to release memory and free other resources.

Return type: None
