I. News

1.1 Recent Version Releases:

The current version of this repository is v2.6.0

1.2 Version Information:

Released on January 29, 2025, PyTorch 2.6 introduces significant enhancements including torch.compile support for Python 3.13, a new dynamic compilation control API torch.compiler.set_stance, and improved AOTInductor packaging and ABI compatibility. Notable highlights also include beta-level FP16 support on X86 CPUs, expanded Intel GPU support with simplified installation, and a backward-incompatible security improvement flipping the default of torch.load to weights_only=True, alongside numerous performance optimizations, bug fixes, and deprecations such as the discontinuation of official Anaconda channel packages.

II. Issues

2.1 Top 5 Active Issues:

We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.

As of our latest update, there are no active issues with ongoing comments this week.

2.2 Top 5 Stale Issues:

We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.

As of our latest update, there are no stale issues for the project this week.

2.3 Open Issues

This section lists, groups, and then summarizes issues that were created within the last week in the repository.

Issues Opened This Week: 0

Summarized Issues:

As of our latest update, there are no open issues for the project this week.

2.4 Closed Issues

This section lists, groups, and then summarizes issues that were closed within the last week in the repository. This section also links the associated pull requests if applicable.

Issues Closed This Week: 1

Summarized Issues:

• ROCm Trunk Job Failures and Kineto Submodule Changes: The ROCm trunk jobs experienced test failures due to changes in the Kineto submodule that initially masked exit code errors. After the removal of a workaround, these errors were re-exposed, causing continuous integration failures and leading to the ROCm trunk jobs being marked as unstable while the issue is addressed.

Key Closed Pull Requests

1. [dynamo][wip] Add contains_impl: This pull request is a work-in-progress update for the Dynamo component in the PyTorch project that aims to add a new feature called contains_impl.

2. Use modernized cuda iterators with CCCL 3.4: This pull request updates the project to use modernized CUDA iterators in line with CCCL 3.4 by replacing deprecated old thrust iterators with more standard aligned iterators.

3. ROCM fix triu/tril for 64-bit indexing for large matrices: This pull request addresses and fixes the triu/tril kernel on ROCm platforms to correctly handle 64-bit indexing for large tensors by implementing a strided loop with a limited grid size to stay within ROCm's thread limit, resulting in significant performance improvements for many data types and tensor shapes while also providing a benchmark to optimize kernel configurations on MI300X hardware.

Other Closed Pull Requests

• Graph splitting optimization for FX inference-only graphs: This pull request introduces a streamlined and optimized graph splitting method by adding split_module_simple() and related utilities. These changes enable lightweight, lazy construction of GraphModule instances for partition submodules, significantly reducing overhead and improving performance by over 5x on large models without causing downstream regressions.
• pull/179839

• Build process migration from setup.py to CMake: This pull request moves several post-build steps such as TORCH_STABLE_ONLY header wrapping, compile_commands.json merging, bundled license generation, Windows export library installation, and macOS OpenMP embedding from setup.py to CMake. It replaces the equivalent logic in setup.py's build_ext.run() while retaining certain macOS and license bundling methods in setup.py due to their specialized handling.
• pull/177644

• Distributed Data Parallel buffer synchronization improvements: This pull request resolves conflicts between broadcast_buffers and init_sync in DDP by introducing a new forward_sync_buffers parameter to control forward-pass buffer syncing independently. It also deprecates broadcast_buffers with a warning when used alongside init_sync=True and updates the relevant documentation accordingly.
• pull/178054

• PyTorch inductor backend convolution dtype check fix: This pull request fixes a bug in the inductor backend by adding a dtype match check between the input tensor and weight in convolution operations. This ensures alignment with eager mode semantics and properly detects and rejects cases where bias is false and dtype mismatches occur.
• pull/179890
