How can the SARI metric be used in a Seq2SeqTrainer compute_metric parameter

[eytan-c]

I want to use the sair metic (#1875 (comment)) as the metric for the trainer, but am stuck on how it can be used, since sari expectes sources, predictions, and references as inputs, while an EvalPrediction object only has the latter two.

Thanks!

Hi! This limitation has been addressed recently in huggingface/transformers#16461, so now you can pass the sources values as inputs to the EvalPrediction object.
