Hello @Qiaolin-Yu, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
Hello! As gemini-code-assist, I've reviewed this pull request to provide a quick summary. Based on the title and the changes, the primary intent of this PR is to update the project's dependency on PyTorch to version 2.7.0. This involves updating dependency specifications in pyproject.toml and adjusting build configurations in Dockerfiles and shell scripts to align with the new PyTorch version and its associated build environments.
Highlights
- PyTorch Version Update: The core change is bumping the required PyTorch version to 2.7.0 across the project's dependencies and build processes.
- Build Environment Alignment: Updates have been made to Dockerfiles and build scripts to use the
pytorch/manylinux2_27-builderimage for CUDA 12.8 builds, which is compatible with PyTorch 2.7.0, replacing the previousmanylinux2_28image.
Changelog
- docker/Dockerfile.blackwell
- Changed the base Docker image from
pytorch/manylinux2_28-builder:cuda12.8topytorch/manylinux2_27-builder:cuda12.8(Line 1). - Updated the
pip3 installcommand for torch to specifically installtorch==2.7.0from the standardcu128index URL, removing the--preandnightlyflags (Line 7).
- Changed the base Docker image from
- python/pyproject.toml
- Specified
torch==2.7.0as the required version for theblackwellextra dependency, replacing the previous unspecifiedtorch(Line 62).
- Specified
- sgl-kernel/build.sh
- Updated the
BUILDER_NAMEvariable for CUDA 12.8 builds frompytorch/manylinux2_28-buildertopytorch/manylinux2_27-builder(Line 21). - Modified the
TORCH_INSTALLcommand for CUDA 12.8 to installtorch==2.7.0from the standardcu128index URL, removing the--preandnightlyflags (Line 29).

Code Review
This pull request aims to upgrade PyTorch to version 2.7.0. While updating dependencies is generally a good practice, there are several critical concerns with the current changes that need to be addressed before this PR can be merged:
- Non-existent Builder Image: Both the
Dockerfile.blackwellandsgl-kernel/build.shscript reference a Docker image (pytorch/manylinux2_27-builder:cuda12.8) that does not appear to be publicly available. This will cause build failures. - PyTorch 2.7.0 Availability: The changes attempt to install
torch==2.7.0from the stable PyTorch WHL index. It's crucial to confirm that this specific version (as a final, non-dev release) is actually available on that index forcu128. If not, installations will fail. - Missing Version Pinning:
torchvisionandtorchaudioversions are not pinned alongsidetorch==2.7.0. This can lead to compatibility issues or non-reproducible builds. - Incomplete PR Checklist: The checklist in the PR description is entirely unchecked. It's important to ensure that all necessary steps like testing, documentation updates, and benchmarking have been completed, especially for a significant dependency upgrade.
These issues need to be resolved to ensure the stability and correctness of the build and runtime environments.
Summary of Findings
- Invalid Docker Builder Image: The specified Docker builder image
pytorch/manylinux2_27-builderis not publicly available, which will cause build failures inDockerfile.blackwellandsgl-kernel/build.sh. - PyTorch 2.7.0 Availability: The PR attempts to install
torch==2.7.0from stable indices. It's crucial to confirm this version is available as a final release, otherwise, installations will fail. - Dependency Version Pinning:
torchvisionandtorchaudioversions are not pinned alongsidetorch==2.7.0, which can lead to compatibility issues or non-reproducible builds. - Incomplete PR Checklist: The checklist in the PR description (covering formatting, tests, documentation, benchmarks) is entirely unchecked. These steps are vital for a dependency upgrade.
Merge Readiness
This pull request is not ready to be merged due to several critical issues. The specified Docker builder image (pytorch/manylinux2_27-builder) appears to be non-existent publicly, which will break the builds. Furthermore, the availability of torch==2.7.0 as a stable release on the targeted indices needs confirmation. Versions for torchvision and torchaudio should also be pinned for stability. Lastly, the PR checklist needs to be completed to ensure all quality gates are met. I recommend addressing these critical and high-severity issues before further consideration for merging. As a reviewer, I am not authorized to approve pull requests; please ensure further review and approval by authorized maintainers once these changes are made.
