The dependency lists for the srt and blackwell extras appear to be identical. To improve maintainability and avoid having to update versions in multiple places, consider defining a common extra that both srt and blackwell can depend on.

For example:

[project.optional-dependencies]
_common_gpu_deps = [
    "torchvision==0.22.1",
    "cuda-python",
    "einops",
    "flashinfer_python==0.2.9rc2",
]
srt = ["sglang[_common_gpu_deps]"]
blackwell = ["sglang[_common_gpu_deps]"]

This would centralize the common dependencies, making future updates easier.

This hardcoded version string is also defined in pyproject.toml. This duplication can lead to inconsistencies if one location is updated but the other is not. To improve maintainability, consider making pyproject.toml the single source of truth and reading the required version from it at runtime. This would ensure the runtime check is always in sync with the installation requirements.
