The original data can be found in the amazon data website.
For example, the meta_Musical_Instruments.json of Amazon_Music can be found here.
The user_rate_item.csv in the code is here (ratings only).
If you want to change the dataset, you can modify the name in the code.
1.process data (You can ignore this step, if you just want to check TMER.)
python data_process.py
2.learn the user and item representations
python data/path/embed_nodes.py
