Frequently Asked Questions

Common questions and troubleshooting guide for Torch-RecHub.

Will there be a TensorFlow version?
- Not currently planned
- This project's core positioning is to provide easy-to-use model implementations for beginners, referencing industry-used models. PyTorch has a wider audience base.
Why is the AUC=0 when running the example?
- The example contains 100 sample data entries, which are meant to demonstrate data format and feature types, ensuring the code runs smoothly. It does not guarantee performance metrics.
- If you need to test performance, you can download the dataset using the links described in the readme, then refer to the parameter configuration file in the example for model training and evaluation.
