Code Review
This pull request correctly refactors the validation metric calculation to use unique identifiers (UIDs) for grouping samples, which is a good improvement for handling multimodal tasks where text prompts can be ambiguous. The implementation is mostly sound. However, I've identified a potential issue in ray_trainer.py where existing UIDs from the dataset are unconditionally overwritten in both the validation and training loops. This could lead to loss of valuable information if the dataset provides stable identifiers. My review includes suggestions to fix this by only generating new UIDs when they are not already present.
