Install Luxar on a machine — from a modest laptop to an NVIDIA-GPU desktop to a Slurm/HPC cluster login node. Use when a user wants to install, set up, or bootstrap Luxar (or fix a broken install): pip install into a venv (Python 3.12 on Ubuntu/macOS, CPU-only torch, extras [gsplats]/[io]/[demos]), GPU acceleration (runtime Metal kernels, NVRTC-compiled CUDA kernels, numba CPU kernels), and the source-checkout dev route: make setup-dev / check-deps / setup-cuda / build-cuda SLURM=1, the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Install Luxar on any machine Luxar is on PyPI. **Most users want `pip install` into a virtual environment**; a source checkout (`make setup-dev`) is for contributors, for building the CUDA extension, and for the few things that need `make` (native app launchers). - **User install (pip)** — view scenes, compile your own, fit splats. Below. - **Dev setup (clone)** — run tests, lint, build the viewer/WASM, build CUDA kernels. Further down. ## Which profile am I on? | Machine | Fitting device | Fast splatting kernels | Notes | | --- | --- | --- | --- | | Laptop / desktop, no GPU (Linux, WSL) | CPU | numba CPU kernels (in `[gsplats]`, compiled on first use) | Viewing is WebGL in the browser and is fine anywhere; install the CPU-only torch wheel first | | Mac with Apple Silicon | `mps` (auto) | Metal, compiled at runtime from a pip install (torch >= 2.7, no Xcode) | | | Desktop with NVIDIA GPU | `cuda` (auto) | CUDA, compiled on first use with NVRTC from a pip install (no toolkit); `make build-cuda` optional | | …

How to install
mdr add royerlab/luxar/luxar-install@sha256:996990bf94689bc3The line at the top of this page pins the label git:20261019.0bf60cc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
