Model Pipeline

image-20240129111934589

  • Pre-training Graph Model Phase. In the pre-training phase, we employ link prediction as the self-supervised task for pre-training the graph model.

  • Producer Phase. In the Producer phase, we employ LLM to summary Node/Neighbor Information.

  • Translator Training Phase.

    ​ Stage 1: Training the Translator for GraphModel-Text alignment.

    ​ Stage 2: Training the Translator for GraphModel-LLM alignment.

  • Translator Generate Phase. Generate the predictions with the pre-trained Translator model.

Installation

We run our experiment with the following settings.

  • CPU: Intel(R) Xeon(R) Platinum 8163 CPU @ 2.50GHz
  • GPU: Tesla V100-SXM2-32GB
  • OS: Linux (Ubuntu 18.04.6 LTS)
  • Python==3.9, CUDA==11.4, Pytorch==1.12.1

The ./requirements.txt list all Python libraries that GraphTranslator depend on, and you can install using:

conda create -n graphtranslator python=3.9
conda activate graphtranslator
git clone https://github.com/alibaba/GraphTranslator.git
cd GraphTranslator/
pip install -r requirements.txt

Datasets & Models

Download datasets and model checkpoints used in this project with huggingface.

ArXiv Dataset

Download files bert_node_embeddings.pt, graphsage_node_embeddings.pt and titleabs.tsv from link and insert them to ./data/arxiv.

cd ./data/arxiv
git lfs install
git clone git@hf.co:datasets/Hualouz/GraphTranslator-arxiv

Translator Model

Download bert-base-uncased.zip from link and unzip it to ./Translator/models.

cd Translator/models/
git lfs install
git clone git@hf.co:Hualouz/Qformer
unzip bert-base-uncased.zip

ChatGLM2-6B Model

Download the ChatGLM2-6B model from link and insert it to ./Translator/models

cd ./Translator/models
git lfs install
git clone git@hf.co:THUDM/chatglm2-6b

Run

Producer Phase

  • Generate node summary text with LLM (ChatGLM2-6B).
cd ./Producer/inference
python producer.py

Training Phase

Train the Translator model with the prepared ArXiv dataset.

  • Stage 1 Training

Train the Translator for GraphModel-Text alignment. The training configurations are in the file ./Translator/train/pretrain_arxiv_stage1.yaml.

cd ./Translator/train
python train.py --cfg-path ./pretrain_arxiv_stage1.yaml

After stage 1, you will get a model checkpoint stored in ./Translator/model_output/pretrain_arxiv_stage1/checkpoint_0.pth.

  • Stage 2 Training

Train the Translator for GraphModel-LLM alignment. The training configurations are in the file ./Translator/train/pretrain_arxiv_stage2.yaml.

cd ./Translator/train
python train.py --cfg-path ./pretrain_arxiv_stage2.yaml

After stage 2, you will get a model checkpoint stored in ./Translator/model_output/pretrain_arxiv_stage2/checkpoint_0.pth.

After all the training stages , you will get a model checkpoint that can translate GraphModel information into that the LLM can understand.

  • Note: Training phase is not necessary if you only want to obtain inference results with our pre-trained model checkpoint. You can download our pre-trained checkpoint checkpoint_0.pth from link and place it in the ./Translator/model_output/pretrain_arxiv_stage2 directory. Then skip the whole Training Phase and go to the Generate Phase.

Generate Phase

  • generate prediction with the pre-trained Translator model. The generate configurations are in the file ./Translator/train/pretrain_arxiv_generate_stage2.yaml. As to the inference efficiency, it may take a while to generate all the predictions and save them into file.
cd ./Translator/train
python generate.py

The generated prediction results will be saved in ./data/arxiv/pred.txt.

Evaluation

Evaluate the accuracy of the generated predictions.

cd ./Evaluate
python eval.py
