Support for Calculating Loss and Accuracy on Validation Data?

[fukudatppei]

I'm currently in the process of training a model and have been tracking the loss and accuracy metrics. However, I've noticed that while I can calculate these metrics for the training data, there isn't a straightforward way to calculate the loss and accuracy for the validation data within the current workflow.

Is there any plan to add support for computing these metrics on validation data in the near future? This feature would be extremely helpful for better evaluating model performance during the development process.

Thank you for considering this request.
