Breaking Changes#

  • TensorFlow 2.10 End of Support: The tensorflow_2_10 single framework DLAMI and virtual environment in multi-framework DLAMIs will reach end of support in a future release. Customers are advised to use previously released DLAMIs for TensorFlow support.

  • Ubuntu 22.04 Single Framework End of Support: Ubuntu 22.04 single framework DLAMIs for PyTorch and JAX will reach end of support in a future release. Customers are advised to use multi-framework or previously released DLAMIs for Ubuntu 22.04.

  • Inf1 virtual environments End of Support: Inf1 virtual environments and AMIs have reached end of support. Use Neuron DLAMIs released up to SDK version 2.26 for Inf1 support.

Neuron DLAMI [2.26.0] (Neuron 2.26.0 Release)#

Breaking 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-neuronx virtual environment in both single and multi-framework DLAMIs.

Neuron DLAMI [2.25.0] (Neuron 2.25.0 Release)#

Date of Release: 07/31/2025

Improvements#

  • All multi-framework virtual environments for the Deep Learning AMIs have been upgraded with the latest Neuron packages to support the AWS Neuron SDK version 2.25.0.

  • Adding support for JAX 0.6 (Amazon Linux 2023, Ubuntu 22.05) single framework DLAMI.

  • Update multi framework DLAMI’s virtual environments to use PyTorch 2.7 and JAX 0.6.

Neuron DLAMI [2.23.0] (Neuron 2.23.0 Release)#

Date of Release: 05/19/2025

Improvements#

  • Adding support for PyTorch 2.6 (Amazon Linux 2023, Ubuntu 22.04) single framework DLAMI.

Date of Release: 04/03/2025

Improvements#

  • Adding PyTorch 2.5 (Amazon Linux 2023, Ubuntu 22.04) and PyTorch 1.13 Inf1 (Ubuntu 22.04) single framework DLAMIs.

  • Adding PyTorch 1.13 Inf1 virtual environments within the Neuron Multi Framework DLAMIs. (Amazon Linux 2023, Ubuntu 22.04).

  • Adding Tensorflow 2.10 Inf1 virtual environments within Multi Framework DLAMI and Tensorflow singleframework DLAMI.
