FreeRec is a personal repository designed for easy data pre-processing and model training.
I am a beginner in the field of recommender systems, so much of FreeRec's designs may not be as effective. In addition, you are free to specify your own framework based on FreeRec.


## Requirements: 

Python == 3.9 | [PyTorch == 1.12.1](https://pytorch.org/) | [TorchData == 0.4.1](https://github.com/pytorch/data) | [PyG](https://pytorch-geometric.readthedocs.io/en/latest/notes/installation.html#) (optional)


```
conda create --name=PyT12 python=3.9
conda activate PyT12
```

### GPU

```
pip install torch==1.12.1+cu113 --extra-index-url https://download.pytorch.org/whl/cu113
