Amazon SageMaker Training Compiler Release Notes

See the following release notes to track the latest updates for Amazon SageMaker Training Compiler.

SageMaker Training Compiler Release Notes: February 13, 2023

Currency Updates

• Added support for PyTorch v1.13.1

Bug Fixes

• Fixed a race condition issue on GPU which was causing NAN loss in some models like vision transformer (ViT) models.

Other Changes

• SageMaker Training Compiler improves performance by letting PyTorch/XLA to automatically override the optimizers (such as SGD, Adam, AdamW) in torch.optim or transformers.optimization with the syncfree versions of them in torch_xla.amp.syncfree (such as torch_xla.amp.syncfree.SGD, torch_xla.amp.syncfree.Adam, torch_xla.amp.syncfree.AdamW). You don't need to change those code lines where you define optimizers in your training script.

Migration to AWS Deep Learning Containers

This release passed benchmark testing and is migrated to the following AWS Deep Learning Container:

• PyTorch v1.13.1

  763104351884.dkr.ecr.us-west-2.amazonaws.com/pytorch-trcomp-training:1.13.1-gpu-py39-cu117-ubuntu20.04-sagemaker

  To find a complete list of the prebuilt containers with Amazon SageMaker Training Compiler, see Supported Frameworks, AWS Regions, Instance Types, and Tested Models.

SageMaker Training Compiler Release Notes: January 9, 2023

Breaking Changes

• tf.keras.optimizers.Optimizer points to a new optimizer in TensorFlow 2.11.0 and later. The old optimizers are moved to tf.keras.optimizers.legacy. You might encounter job failure due to the breaking change when you do the following.

  • Load checkpoints from an old optimizer. We recommend you to switch to use the legacy optimizers.

  • Use TensorFlow v1. We recommend you to migrate to TensorFlow v2, or switch to the legacy optimizers if you need to continue using TensorFlow v1.

  For more detailed list of breaking changes from the optimizer changes, see the official TensorFlow v2.11.0 release notes in the TensorFlow GitHub repository.

SageMaker Training Compiler Release Notes: December 8, 2022

Bug Fixes

• Fixed the seed for PyTorch training jobs starting PyTorch v1.12 to ensure that there is no discrepancy in model initialization across different processes. See also PyTorch Reproducibility.

• Fixed the issue causing PyTorch distributed training jobs on G4dn and G5 instances to not default to communication through PCIe.

Known Issues

• Improper use of PyTorch/XLA APIs in Hugging Face’s vision transformers might lead to convergence issues.

Other Changes

• When using the Hugging Face Transformers Trainer class, make sure that you use SyncFree optimizers by setting the optim argument to adamw_torch_xla. For more information, see Large Language Models Using the Hugging Face Transformers Trainer Class. See also Optimizer in the Hugging Face Transformers documentation.
