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 FP16 support on x86 CPUs, expanded Intel GPU support, FlexAttention for x86 CPUs targeting LLMs, and a backward-incompatible security improvement flipping the default of torch.load to weights_only=True, alongside the deprecation of official Conda package publishing.

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.

1. [TRIAGE REVIEW] [MODULE: CRASH] [MODULE: WINDOWS] [MODULE: REGRESSION] [ONCALL: PT2] [MODULE: DYNAMIC SHAPES] [MODULE: INDUCTOR] [MODULE: EMPTY TENSOR] [BOT-TRIAGED] Pytorch 2.11 regression: Division by zero exception on empty tensor with torch.compile and dynamic size: This issue reports a regression in PyTorch 2.11 where using torch.compile(dynamic=True) causes a ZeroDivisionError when a compiled function is called with an empty tensor (y-dimension zero) and the kernel uses the Grid2DWithYZOverflow grid type. The problem stems from the dynamically generated Triton kernel launcher performing a division by zero due to the handling of unbounded symbolic integer dimensions, which was not an issue in earlier versions like 2.10.

   • The comments discuss the nature of the error, confirming it occurs in the generated code for dynamic but bounded shapes, and clarify that a recent pull request does not fix this specific issue. Users provide error stack traces and confirm the bug is absent in version 2.10, indicating a regression introduced in 2.11, and suggest fixes involving guarding against zero divisions in the kernel launcher code.
   • Number of comments this week: 9

2. [ONCALL: PT2] [MODULE: INDUCTOR] [UPSTREAM TRITON] [MODULE: FLEX ATTENTION] [Bug][Flex Attention] Flex Attention crashes with LLVM error after triton version bump: This issue reports a crash occurring in the Flex Attention module after a Triton version bump, caused by an LLVM assertion failure in the SLP vectorizer during compilation of certain Triton kernels. The problem can be temporarily mitigated by disabling LLVM optimizations, and a suggested fix involves upstreaming a change to Triton that disables SLP vectorization while preserving other optimization passes.

   • The comments include notifications to relevant developers, a proposed patch to disable SLP vectorization in LLVM as a targeted workaround, discussion about the appropriateness of this fix, and suggestions for more precise environment variable settings to avoid disabling the entire LLVM optimization pipeline.
   • Number of comments this week: 7

3. [ONCALL: DISTRIBUTED] [TRIAGED] [MODULE: DTENSOR] [DTensor] reshape is dispatched to aten.view instead of aten.reshape: This issue addresses a problem where DTensor.reshape() incorrectly dispatches to aten.view.default instead of aten.reshape.default for sharded DTensors because is_contiguous() returns True based on global stride metadata without considering sharding placement. This behavior prevents triggering redistribution with strict_view=False, and the discussion suggests that the fix should occur at the aten layer rather than the Python DTensor layer, as the current workaround involves overriding is_contiguous() or modifying reshape dispatch in DTensor.

   • The comments identify the root cause as DTensor.is_contiguous() always returning True for sharded tensors, leading to incorrect dispatch; various approaches are considered, including overriding is_contiguous() or using torch_function, but the consensus is that the proper fix belongs in the aten layer, with contributors discussing who should implement it and deferring the Python-layer fixes.
   • Number of comments this week: 7

4. [HIGH PRIORITY] [TRIAGE REVIEW] [MODULE: BINARIES] [BOT-TRIAGED] [BOT-MISLABELED] import torch fails with release 2.11 on python 3.13, AST parsing error (IndentationError): This issue reports that importing the PyTorch library version 2.11 fails with Python 3.13.8 due to an IndentationError during AST parsing, while it works correctly with Python 3.12 and the latest Python 3.13.11. The error appears related to the use of JIT decorators in the code, and updating to Python 3.13.11 resolves the problem, suggesting compatibility issues with earlier Python 3.13 versions.

   • The comments confirm the issue is reproducible on Python 3.13.8 but not on 3.13.11, recommend upgrading Python to fix the error, discuss potentially removing problematic JIT decorators for newer Python versions, and conclude with the original reporter acknowledging the fix and asking if the issue should be closed.
   • Number of comments this week: 5

5. [MODULE: SPARSE] [TRIAGED] [MODULE: REGRESSION] [BOT-TRIAGED] check_invariants does not silence warning for torch.sparse_csr_tensor: This issue reports that the check_invariants parameter in the torch.sparse_csr_tensor constructor does not suppress a warning about sparse invariant checks, which is unexpected behavior in PyTorch version 2.11. The user highlights confusion around the documentation and suggests that while the check_invariants argument is intended to enable or disable invariant checks, it should not trigger a warning when used, indicating a potential inconsistency or redundancy in the API design.

   • The comments clarify that the documentation does not explicitly state that check_invariants silences the warning, but rather controls the enabling or disabling of invariant checks; users discuss the possibility of using a context manager to suppress warnings and agree that the current behavior of check_invariants on the constructor is somewhat redundant and could be improved.
   • Number of comments this week: 5

2.2 Top 5 Stale Issues:
