Date of release: September 18, 2025
Go back to the AWS Neuron 2.26.0 release notes home
Improvements#
We’ve added the following improvements for DLAMI support in this release of the AWS Neuron SDK:
Support for PyTorch 2.8 (Amazon Linux 2023, Ubuntu 22.04) single-framework DLAMI
Updates multi-framework DLAMI virtual environments to support PyTorch 2.8
All Neuron packages and their dependencies have been upgraded to support version 2.26.0 of the AWS Neuron SDK
Behavioral changes#
End-of-support for the Transformers NeuronX library starts with the 2.26.0 release of the AWS Neuron SDK. As a result, the PyTorch inference Deep Learning Container (DLC) will no longer provide the
transformers-neuronxvirtual environment in both single and multi-framework DLAMIs. For more details, see Announcing end of support for Transformers NeuronX library starting in Neuron 2.26 release.
