Introduction

This repository brings an implementation of T5 for translation in PT-EN tasks using a modest hardware setup. We propose some changes in tokenizator and post-processing that improves the result and used a Portuguese pretrained model for the translation. You can collect more informations in our repository. Also, check our paper!

Usage

Just follow "Use in Transformers" instructions. It is necessary to add a few words before to define the task to T5.

You can also create a pipeline for it. An example with the phrase " Eu gosto de comer arroz" is:

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM, pipeline
  
tokenizer = AutoTokenizer.from_pretrained("unicamp-dl/translation-pt-en-t5")

model = AutoModelForSeq2SeqLM.from_pretrained("unicamp-dl/translation-pt-en-t5")

pten_pipeline = pipeline('text2text-generation', model=model, tokenizer=tokenizer)

pten_pipeline("translate Portuguese to English: Eu gosto de comer arroz.")
