Deprecated

The previous configuration file is supported in 0.4.1 but it will be deprecated in a future version. Please, remember to update your local configuration files:

• The edge_builder field is renamed to edge_builders, which now requires a list.
• The source/target_mask_attr_name fields are now specified inside each edge builder.

0.3.0 Anemoi-graphs, minor release

Added

HEALPixNodes - nodebuilder based on Hierarchical Equal Area isoLatitude Pixelation of a sphere.

Inspection tools: interactive plots, and distribution plots of edge & node attributes.

Graph description print in the console.

CLI entry point: 'anemoi-graphs inspect ...'.

added downstream-ci pipeline and cd-pypi reusable workflow

Changelog release updater

Create package documentation.

Changed

fix: added support for Python3.9.
fix: bug in graph cleaning method
fix: anemoi-graphs create CLI argument is casted to a Path.
ci: fix missing binary dependency in ci-config.yaml
fix: Updated get_raw_values method in AreaWeights to ensure compatibility with scipy.spatial.SphericalVoronoi by converting latitudes and longitudes to NumPy arrays before passing them to the latlon_rad_to_cartesian function. This resolves an issue where the function would fail if passed Torch Tensors directly.
ci: Reusable workflows for push, PR, and releases
ci: ignore docs for downstream ci
ci: changed Changelog action to create PR
ci: fixes and permissions on changelog updater

0.2.1 - Anemoi-graph Release, bug fix release

What's Changed

• Fix The 'save_path' argument of the GraphCreator class is optional, allowing users to create graphs without saving them by @JPXKQX in #24

Full Changelog: https://github.com/ecmwf/anemoi-graphs/blob/develop/CHANGELOG.md#021---anemoi-graph-release-bug-fix-release

Git diff: 0.2.0...0.2.1

0.2.0

Second release of global graphs:

• node builders: HexNodes, TriNodes
• edge builders: MultiScaleEdges (valid for TriNodes & HexNodes)

This enables building nodes from refined icosahedrons (using third-party libraries trimesh and h3)

0.1.0

First release of global graphs:

• node builders: ZarrDatasetNodes and NPZFileNodes
• edge builders: CutoffEdges and KNNEdges
• node attributes: UniformWeights and AreaWeights
• edge attributes: EdgeDirection and EdgeLength
• CLI

This enables building graphs for Anemoi-training on-the-fly.
