This release is a pre-release and may not be stable for production use.
GraphAr Python SDK
GraphAr Python SDK provides Python bindings for the GraphAr C++ library, allowing user to work with GraphAr formatted graph data in Python environments. It includes both a high-level API for data manipulation and a command-line interface for common operations.
Installation
Prerequisites
- Python >= 3.7
- pip (latest version recommended)
- CMake >= 3.15 (for building from source)
- Apache Arrow >= 12.0 (for building from source)
Install from Pypi
Install the latest released version from PyPI:
pip install -U graphar
Install from Source
Clone the repository and install the Python package:
git clone https://github.com/apache/incubator-graphar.git
cd incubator-graphar
pip install ./python
For verbose output during installation:
pip install -v ./python
Using Docker (Recommended)
The easiest way to get started is by using our pre-configured Docker environment:
docker run -it ghcr.io/apache/graphar-dev
Quick Start
Importing the Package
After installation, you can import the GraphAr Python SDK in your Python scripts:
import graphar
Basic Usage
Loading graph information:
import graphar
# Load graph info from a YAML file
graph_info = graphar.graph_info.GraphInfo.load("path/to/graph.yaml")
# Access vertex information
vertex_info = graph_info.get_vertex_info("person")
print(f"Vertex type: {vertex_info.get_type()}")
# Access edge information
edge_info = graph_info.get_edge_info("person", "knows", "person")
print(f"Edge type: {edge_info.get_edge_type()}")
Command-Line Interface
GraphAr Python SDK also provides a command-line interface for common operations such as checking metadata, showing graph information, and importing data.
For detailed information about the CLI functionality, please see CLI Documentation.
API Documentation
build docs
make install_docs
make docs
The Python SDK exposes the core GraphAr functionality through several modules:
graphar.graph_info: Main API for working with graph, vertex, and edge informationgraphar.high_level: High-level API for data reading and writing
Examples
[!NOTE] under development.
You can find various examples in the examples directory which demonstrate usage of the underlying C++ library. These concepts translate directly to the Python SDK.
Development
To contribute to the Python SDK, please follow the guidelines in the main CONTRIBUTING.md file.
