Holoscan Conda Installation

Purpose

Install the Holoscan SDK (Python runtime and/or C++ dev headers) into a Conda environment on Linux x86_64, using conda-forge + rapidsai with a correctly pinned CUDA metapackage.

Prerequisites

• Linux x86_64 with an NVIDIA GPU and CUDA 13 driver (check nvidia-smi).
• conda (Miniforge preferred). Step 1 installs it if missing.
• Network access to conda-forge, rapidsai, and docs.nvidia.com.

Limitations

• CUDA 13 only (since v4.3.0 — earlier releases were CUDA 12). If the user has a CUDA 12 driver, redirect to /holoscan-install-container or /holoscan-install-wheel instead.
• Linux x86_64 only — no aarch64/iGPU support on conda-forge.
• ulimit -s 32768 is recommended in every shell that runs Holoscan — without it, some apps may segfault.
