You can specify platform specific wheels in your pyproject.toml

    [[tool.uv.index]]
    name = "pytorch-cu124"
    url = "https://download.pytorch.org/whl/cu124"
    explicit = true
    [[tool.uv.index]]
    name = "pytorch-cpu"
    url = "https://download.pytorch.org/whl/cpu"
    explicit = true
    [tool.uv.sources]
    torch = [
    { index = "pytorch-cu124", marker = "platform_system != 'Darwin'" },
    { index = "pytorch-cpu", marker = "platform_system == 'Darwin'" },
    ]
