## Summary This is a prototype that I'm considering shipping under `--preview`, based on [`light-the-torch`](https://github.com/pmeier/light-the-torch). `light-the-torch` patches pip to pull PyTorch packages from the PyTorch indexes automatically. And, in particular, `light-the-torch` will query the installed CUDA drivers to determine which indexes are compatible with your system. This PR implements equivalent behavior under `--torch-backend auto`, though you can also set `--torch-backend cpu`, etc. for convenience. When enabled, the registry client will fetch from the appropriate PyTorch index when it sees a package from the PyTorch ecosystem (and ignore any other configured indexes, _unless_ the package is explicitly pinned to a different index). Right now, this is only implemented in the `uv pip` CLI, since it doesn't quite fit into the lockfile APIs given that it relies on feature detection on the currently-running machine. ## Test Plan On macOS, you can test this with (e.g.): ```shell UV_TORCH_BACKEND=auto UV_CUDA_DRIVER_VERSION=450.80.2 cargo run \ pip install torch --python-platform linux --python-version 3.12 ``` On a GPU-enabled EC2 machine: ```shell ubuntu@ip-172-31-47-149:~/uv$ UV_TORCH_BACKEND=auto cargo run pip install torch -v Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.31s Running `target/debug/uv pip install torch -v` DEBUG uv 0.6.6 (e95ca063b 2025-03-14) DEBUG Searching for default Python interpreter in virtual environments DEBUG Found `cpython-3.13.0-linux-x86_64-gnu` at `/home/ubuntu/uv/.venv/bin/python3` (virtual environment) DEBUG Using Python 3.13.0 environment at: .venv DEBUG Acquired lock for `.venv` DEBUG At least one requirement is not satisfied: torch warning: The `--torch-backend` setting is experimental and may change without warning.
