Usage

Introduction

This project demonstrates how to run a workflow locally using the OneCompute platform. The provided code snippet utilizes the dnv-oneworkflow Python package to interact with the OneCompute platform and execute a simple workflow locally. The example showcases the setup of the local workflow runtime service and the submission of a job for execution.

Prerequisites

Make sure you have the following prerequisites installed:

• Python 3.10.x or higher

• Pip (Python package manager)

• dnv-oneworkflow Python package for the PythonCommand module.

  Use the following command to install the dnv.oneworkflow package:

  pip install dnv.oneworkflow
  

• Install the LocalWorkflowRuntimeService using the following command within your Python environment:

  await PackageManager().install_package_async(
      "LocalWorkflowRuntime", "win-x64", PackageManager.Repository.DEV
  )
