[UPDATE]: Hi! I might have this done by this month (train mt5 for Spanish QA and Abstractive Summarization), I will comment here again once I upload it to the models hub. I am first checking the results I get doing it with English datasets, and I will use Spanish after that (I don’t have much computer resources so it takes me a lot of time and I prefer to test with English which I guess would definitely work to solve any issues I may have, and then with Spanish once I can be sure I am not going to spend too much time with something that may not work  )
