pyholos 0.4.0

A Python package for running the HOLOS 4.0 CLI.

PyHolos

A Python wrapper for the HOLOS 4.0 CLI - enabling estimations of Canadian agricultural greenhouse gas emissions.

Overview

PyHolos provides a Python interface to the HOLOS CLI, allowing you to:

• Launch HOLOS simulations from Python scripts
• Model farm systems with minimal input data (PyHolos estimates missing parameters)
• Generate structured input files for the HOLOS CLI
• Process and visualize simulation results

Features

• Farm Modeling: Support for livestock (beef, dairy, sheep) and land management systems (crops, carbon sequestration)
• Data Integration: Automatic integration with Soil Landscapes of Canada (SLC) data
• Flexible Input: Work with JSON configurations or pre-structured farm data
• Post-processing: Built-in tools for analyzing and plotting simulation results

Requirements

• Python >= 3.12
• Dependencies: geojson, shapely, pandas, pydantic

Installation

For detailed installation instructions including prerequisites (Git, conda, PyCharm setup), see the documentation.

Quick Start

from pathlib import Path
from pyholos import launching

# Launch HOLOS using a JSON farm configuration
launching.launch_holos(
    path_dir_farms=Path('path/to/farm_data'),
    name_farm_json='farm.json',
    path_dir_outputs=Path('path/to/outputs'),
    id_slc_polygon=851003
)

See the examples directory for more usage patterns.
