I would like to do fine-tuning of pretrained models on my domain-specific dataset. MarianMT pretrained models are available on many bilinguals.
I would like to know how we can train either a translation model from scratch or do the finetuning of available pretrained models.
The code for MarianMT tokenizer is there and i saw MarianMT inherits the config of BART for its architecture but i am not sure about how to fine-tune  for my datasets.
