cugraph_dgl

Description

RAPIDS cugraph_dgl provides a duck-typed version of the DGLGraph class, which uses cugraph for storing graph structure and node/edge feature data. Using cugraph as the backend allows DGL users to access a collection of GPU accelerated algorithms for graph analytics, such as centrality computation and community detection.

Conda

Install and update cugraph-dgl and the required dependencies using the command:

conda install mamba -n base -c conda-forge
mamba install cugraph-dgl -c rapidsai-nightly -c rapidsai -c pytorch -c conda-forge -c nvidia -c dglteam

Build from Source

Create the conda development environment

mamba env create -n cugraph_dgl_dev --file conda/cugraph_dgl_dev_11.6.yml

Install in editable mode

pip install -e . 

Run tests

pytest tests/*
