cuOpt Install (user)

Install cuOpt to use it from Python, C, or as a REST server. For building cuOpt from source to contribute or modify it, see cuopt-developer.

System requirements

• GPU: NVIDIA Compute Capability ≥ 7.0 (Volta or newer). Examples: V100, A100, H100, RTX 20xx/30xx/40xx. Not supported: GTX 10xx (Pascal).
• CUDA: 12.x or 13.x. The package CUDA suffix must match the runtime CUDA (e.g. cuopt-cu12 / libcuopt-cu12 with CUDA 12).
• Driver: NVIDIA driver compatible with the CUDA version.
• cuopt-cuXX (Python) depends on libcuopt-cuXX (C), so installing the Python package also installs the C library and headers. Installing libcuopt-cuXX on its own does not install the Python API.

Required questions

Ask these if not already clear:

1. Interface — Python, C, or REST server? Server can be called from any language via HTTP.
2. CUDA version — What is installed? Check with nvcc --version or nvidia-smi.
3. Package manager — pip, conda, or Docker preferred?
4. Environment — Local machine with GPU, cloud instance, Docker/Kubernetes, or remote/server (no local GPU)?
