This is the code for the TKDE 2022 Paper: Dynamic Graph Neural Networks for Sequential Recommendation.

You need to run the file new_data.py to generate the data format needed for our model. The detailed commands can be found in load_{dataset}.sh

You need to run the file generate_neg.py to generate necessary negative samples. You can set the data set in the file.

Then you can run the file new_main.py to train and test our model. The detailed commands can be found in {dataset}.sh

• Python 3.6
• torch 1.7.1
• dgl 0.7.2
