Stash

The Stash acts as a flexible container for user-defined data structures. In the field of Recommender Systems, which is constantly evolving, providing a one-size-fits-all solution for every scenario is inherently difficult. The Stash mechanism allows developers to persist arbitrary data that can be retrieved later during training or evaluation.

The main way to interact with the Stash is through the WarpRec Callback System, which provides hooks at key stages of the data processing and training pipeline. You can find the full documentation of the callback system here. Another way to access the Stash is through a custom script that directly interacts with WarpRec's internal components.
