DLS2

Introduction

This project contains the main dls framework

Documentation and installation

Please refer to the repo dls2-barebone for documentation, dependencies and installation of the DLS2 framework.

Python deps

They can be installed through dockerfile or in the container directly using the following command:

PYTHON_EXECUTABLE=/usr/lib/dls2/python/bin/python3 dls2/scripts/install_py_runtime_deps.sh /path/to/requirements.txt

When dls2-runtime is built and installed, a private interpreter (/usr/lib/dls2/python/bin/python3) appears. That specific interpreter has specific permissions allowing for realtime capabilities. More precisely, /usr/lib/dls2/python/bin/python3 is a relocated interpreter binary, with an isolated Python environment. If /usr/lib/dls2/python/bin/python3 does not exist yet when the cited script is executed, the script itself bootstraps the DLS2 virtual environment from /usr/bin/python3, installs the requirements into that isolated environment, and after dls2-runtime is installed the same interpreter path is reused with realtime-capable permissions.
