Highlights

We are excited to announce the release of PyTorch 1.11. This release is composed of over 3,300 commits since 1.10, made by 434 contributors. Along with 1.11, we are releasing beta versions of TorchData and functorch. We want to sincerely thank our community for continuously improving PyTorch.

• TorchData is a new library for common modular data loading primitives for easily constructing flexible and performant data pipelines. View it on GitHub.
• functorch, a library that adds composable function transforms to PyTorch, is now available in beta. View it on GitHub.
• Distributed Data Parallel (DDP) static graph optimizations available in stable.

You can check the blogpost that shows the new features here.

Backwards Incompatible changes

Python API

Fixed python deepcopy to correctly copy all attributes on Tensor objects (#65584)

This change ensures that the deepcopy operation on Tensor properly copies all the attributes (and not just the plain Tensor properties).

General Overview

Releasing a new version of PyTorch generally entails 3 major steps:

0. Cutting a release branch preparations
1. Cutting a release branch and making release branch specific changes
2. Drafting RCs (Release Candidates), and merging cherry picks
3. Promoting RCs to stable and performing release day tasks

Cutting a release branch preparations

Following Requirements needs to be met prior to final RC Cut:

• Resolve all outstanding issues in the milestones(for example 1.11.0)before first RC cut is completed. After RC cut is completed following script should be executed from builder repo in order to validate the presence of the fixes in the release branch : python github_analyze.py --repo-path ~/local/pytorch --remote upstream --branch release/1.11 --milestone-id 26 --missing-in-branch
• Validate that all new workflows have been created in the PyTorch and domain libraries included in the release. Validate it against all dimensions of release matrix, including operating systems(Linux, MacOS, Windows), Python versions as well as CPU architectures(x86 and arm) and accelerator versions(CUDA, ROCm).
