Holoscan pip Wheel Installation

Purpose

Install the Holoscan SDK Python bindings via the holoscan-cu12 / holoscan-cu13 pip wheel into a virtual environment, and verify with hello_world and video_replayer.

Prerequisites

• Linux x86_64 with NVIDIA GPU + driver (nvidia-smi).
• CUDA Toolkit on PATH matching the host CUDA major (12 or 13).
• Python 3.10–3.13 with venv available.
• Network access to PyPI and docs.nvidia.com.

Limitations

• Python only. For C++ headers/libs, pair with /holoscan-install-debian.
• holoscan-cu12 and holoscan-cu13 are mutually exclusive — wheel must match host CUDA driver.
• video_replayer data ships only with the Debian package; without it, set HOLOSCAN_INPUT_PATH to a directory containing racerx/.
• ulimit -s 32768 is recommended in every shell that runs Holoscan — without it some apps emit a stack-size warning or, in rarer cases, segfault.
