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. [MPS] Performance regression and visual bug with ComfyUI Flux dev since nightly 20250510: This issue reports a performance regression and visual artifact in the ComfyUI denoising preview when using nightly builds of torch from May 11, 2025, onwards, on a 64GB M3 Max MacBook Pro. The problem is reproducible and appears to be linked to torch, as reverting to the May 10, 2025, nightly build resolves the issue, suggesting a change in torch is the cause.

    • The comments discuss attempts to reproduce the issue, with requests for workflow files and download links for checkpoint files. Some users report not experiencing the performance regression or artifacts, while others identify a specific pull request as the source of the visual artifact. It is noted that the performance difference is observed only when the preview is enabled, and disabling it stabilizes performance across versions.
    • Number of comments this week: 12
  2. High-performance LLM quantization on X86 CPU with native PyTorch: This issue discusses the implementation of high-performance quantization for large language models (LLMs) on X86 CPUs using native PyTorch, aiming to enhance storage efficiency, reduce memory usage, and decrease inference latency. The feature supports various configurations and aims to provide performance comparable to popular LLM serving frameworks, allowing PyTorch users to achieve efficient quantization with a native experience.

    • The comments discuss adding and removing pull requests related to the feature, with some concerns about potential confusion in the description regarding quantization types. There is ongoing communication about the status of certain pull requests, with requests for links and updates on their progress. Additionally, a request for a review of the release feature is made.
    • Number of comments this week: 9
  3. Reproducibility of results without AVX512 by setting ATEN_CPU_CAPABILITY=avx2: This issue highlights a discrepancy in the reproducibility of results when running a PyTorch script on machines with and without AVX-512 support, even when the environment variable ATEN_CPU_CAPABILITY is set to avx2. The user reports that despite attempts to disable AVX-512 in both ATEN and MKL, different results are observed, suggesting that AVX-512 might still be utilized elsewhere in the system.

    • The comments discuss potential reasons for the discrepancy, including the role of MKL and the limitations of testing in virtual machines. Suggestions are made to verify results on physical machines, and it is noted that the issue might be related to the specific machine rather than AVX2/AVX512 capabilities. The user clarifies that the discrepancy is observed on multiple physical machines, indicating a broader issue with AVX-512 usage beyond ATEN settings.
    • Number of comments this week: 8
  4. nn.RNN(...).to('cuda') fails with cuDNN error: CUDNN_STATUS_BAD_PARAM on GPU, but works on CPU: This issue describes a problem where a simple nn.RNN model in PyTorch runs correctly on a CPU but fails on a GPU with a cuDNN_STATUS_BAD_PARAM error when attempting to transfer the model to CUDA. The error appears to be related to the initialization of cuDNN parameters during the flatten_parameters() process, which occurs when the model is moved to the GPU.

    • The comments reveal that the issue is reproducible on certain GPUs with cuDNN version 8.9, but not on others with newer versions. It is suggested that upgrading to cuDNN 9.3.0 resolves the problem, indicating a compatibility issue with older cuDNN versions. The discussion highlights the need for PyTorch to provide clearer guidance on supported cuDNN versions to prevent similar issues.
    • Number of comments this week: 8
  5. Hangs on torch.tril on Intel GPU: This issue reports a bug where the torch.tril operation hangs when executed on an Intel GPU, specifically when running a script that involves creating a large boolean tensor and applying the tril function. The problem persists even after updating to a newer version of PyTorch, and it is suspected to be related to an integer index overflow in the tril operation.

    • The comments involve assigning the issue to specific team members, labeling it under the appropriate module, and discussing the inability to reproduce the issue on some systems. Additional details about the system environment are requested, and it is noted that the issue might be related to an integer index overflow, as the operation hangs indefinitely on the device side.
    • Number of comments this week: 7

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.

  1. ImportError: cannot import name 'triton_key' from 'triton.compiler.compiler': This issue involves an ImportError encountered when attempting to import 'triton_key' from 'triton.compiler.compiler', which is causing a backend compiler failure in a PyTorch environment. The error occurs within a script that utilizes the OotdPipeline and involves compiling components with Torch's compile function, specifically affecting the 'inductor' backend due to the missing import.
  2. Alternate algorithm for computing MaxPool2D under specific condition.: This issue proposes an alternative algorithm for computing MaxPool2D in PyTorch when the stride is equal to 1, suggesting that a kernel size of 5 can be represented by two MaxPool2D operations with a kernel size of 3, and similarly, a kernel size of 7 can be represented by three such operations. The motivation behind this approach is to reduce computational costs on the CPU by modifying the MaxPool2D layer directly, as demonstrated by testing code that shows a significant speedup in execution time compared to the traditional method.
  3. cuda_utils.so: failed to map segment from shared object: This issue involves a problem encountered when running a PyTorch model within a Docker container, where the execution of a cached shared object file, cuda_utils.so, fails due to a missing execution permission despite being run as the root user. The error occurs in a setup with a tmpfs directory having permissions set to 1777, and the problem is specifically related to the inability to map a segment from the shared object, which is crucial for the model's execution.
  4. Enable UFMT on all files in PyTorch: This issue involves enabling uniform formatting (UFMT) across all files in the PyTorch codebase, as currently, approximately 1,500 files are not formatted according to the UFMT standards. The process requires removing file names from the exclude_patterns in the UFMT section of the .lintrunner.toml file and running a specific command to apply the formatting, with additional preparatory work needed to resolve known issues such as import cycles and misplaced annotations before the UFMT changes can be committed.
  5. [JIT archive] Add a flag to not include debug files: This issue proposes the addition of a flag to the torch.jit.save() function in PyTorch to exclude .debug_pkl files, which are primarily used for debugging purposes and can significantly increase the file size of JIT archives. The motivation behind this feature request is to reduce the size of model files, particularly for deployment on mobile devices, where storage space is limited, as demonstrated by the user's experience of reducing a model's file size from 6.7MB to 5.6MB by manually removing these debug files.
