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 performance control API torch.compiler.set_stance, and improved AOTInductor packaging and ABI compatibility. Notable highlights also include FP16 support on X86 CPUs, expanded Intel GPU support, a backward-incompatible security change flipping the default of torch.load to weights_only=True, and the deprecation of official Conda package publishing, reflecting a trend toward improved performance, security, and streamlined deployment.

Key Closed Pull Requests
1. Triton backward convolution kernel: This pull request implements Triton kernels for 2D convolution backward operations in TorchInductor, replacing the previous ATen-only fallback approach, and includes new templates, backend selection logic, layout computations, extensive parameterized tests, and achieves up to 20% performance improvement on MI325 GPUs for certain small-batch workloads.

2. fix for uncompatible tensor shape being ignored in torch.compile: This pull request addresses a bug in torch.compile(dynamic=True) where incompatible tensor shapes for the out= argument were silently ignored by fixing the py_impl stub for aten.empty.out to properly resize the output tensor, ensuring behavior consistent with eager mode and raising errors when memory_format is incompatible.
- URL: pull/178825
3. [Stable C Shim] Shim functions to retrieve error message: This pull request introduces two new C shim functions to retrieve error messages and backtraces from c10::Error exceptions caught by a specific macro, along with a new macro to provide detailed error information, updates tests and documentation, and modifies the existing error-handling behavior to no longer print backtraces directly.
- URL: pull/180135
Other Closed Pull Requests
- Test improvements and fixes: Multiple pull requests enhance test reliability and clarity by changing data types for numerical accuracy, removing decorators to enable broader testing on specific GPUs, and fixing flaky tests by explicitly specifying gradient arguments. These changes ensure more robust and clear testing outcomes across different hardware and scenarios.
- [pull/178181, pull/179704]
- ROCm memory allocator enhancements: A pull request modifies the CUDACachingAllocator to bypass per-arena memory limit computations specifically for ROCm custom memory pools, preventing false out-of-memory errors and deadlocks on MI300X devices with complex multi-device topologies. This update preserves existing behavior for standard CUDA allocators while addressing ROCm-specific issues.
