GraphVite - graph embedding at high speed and large scale

Docs | Tutorials | Benchmarks | Pre-trained Models

GraphVite is a general graph embedding engine, dedicated to high-speed and large-scale embedding learning in various applications.

GraphVite provides complete training and evaluation pipelines for 3 applications: node embedding, knowledge graph embedding and graph & high-dimensional data visualization. Besides, it also includes 9 popular models, along with their benchmarks on a bunch of standard datasets.

Here is a summary of the training time of GraphVite along with the best open-source implementations on 3 applications. All the time is reported based on a server with 24 CPU threads and 4 V100 GPUs.

Training time of node embedding on Youtube dataset.

Training / evaluation time of knowledge graph embedding on FB15k dataset.

Training time of high-dimensional data visualization on MNIST dataset.

Requirements

Generally, GraphVite works on any Linux distribution with CUDA >= 9.2.

The library is compatible with Python 2.7 and 3.6/3.7.

Installation

From Conda

conda install -c milagraph -c conda-forge graphvite cudatoolkit=$(nvcc -V | grep -Po "(?<=V)\d+.\d+")

If you only need embedding training without evaluation, you can use the following alternative with minimal dependencies.

conda install -c milagraph -c conda-forge graphvite-mini cudatoolkit=$(nvcc -V | grep -Po "(?<=V)\d+.\d+")

From Source

Before installation, make sure you have conda installed.

git clone https://github.com/DeepGraphLearning/graphvite
cd graphvite
conda install -y --file conda/requirements.txt
mkdir build
cd build && cmake .. && make && cd -
cd python && python setup.py install && cd -

On Colab

!wget -c https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
!chmod +x Miniconda3-latest-Linux-x86_64.sh
!./Miniconda3-latest-Linux-x86_64.sh -b -p /usr/local -f

!conda install -y -c milagraph -c conda-forge graphvite \
    python=3.6 cudatoolkit=$(nvcc -V | grep -Po "(?<=V)\d+\.\d+")
!conda install -y wurlitzer ipykernel

Quick Start

Here is a quick-start example of the node embedding application.

graphvite baseline quick start

Typically, the example takes no more than 1 minute. You will obtain some output like

Batch id: 6000
loss = 0.371041

------------- link prediction --------------
AUC: 0.899933

----------- node classification ------------
macro-F1@20%: 0.242114
micro-F1@20%: 0.391342

Baseline Benchmark

To reproduce a baseline benchmark, you only need to specify the keywords of the experiment. e.g. model and dataset.

graphvite baseline [keyword ...] [--no-eval] [--gpu n] [--cpu m] [--epoch e]

You may also set the number of GPUs and the number of CPUs per GPU.

Use graphvite list to get a list of available baselines.

Custom Experiment

Create a yaml configuration scaffold for graph, knowledge graph, visualization or word graph.

graphvite new [application ...] [--file f]

Fill some necessary entries in the configuration following the instructions. You can run the configuration by

graphvite run [config] [--no-eval] [--gpu n] [--cpu m] [--epoch e]

High-dimensional Data Visualization

You can visualize your high-dimensional vectors with a simple command line in GraphVite.

graphvite visualize [file] [--label label_file] [--save save_file] [--perplexity n] [--3d]

The file can be either a numpy dump *.npy or a text matrix *.txt. For the save file, we recommend to use png format, while pdf is also supported.
