How to train bilingual models?
In [language_modeling](https://github.com/huggingface/transformers/tree/master/examples/flax/language-modeling) examples, there is an script to train a T5 model for a language. I would like to know how can I use or change this script to train a bilingual language for X and Y languages? Is it possible to do if via this code? 

Also I would like to know if it's possible to initialize training from a multilingual model like `mt5`, and then use training data for one or two languages  for further training?
