ptt5-v2 models are pretrained T5 models tailored for the Portuguese language, continuing from Google's original checkpoints with sizes from t5-small to t5-3B. These checkpoints were used to train MonoT5 rerankers for the Portuguese language, which can be found in their HuggingFace collection. For further information about the pretraining process, please refer to our paper, ptt5-v2: A Closer Look at Continued Pretraining of T5 Models for the Portuguese Language.

Usage

python

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("unicamp-dl/ptt5-v2-3b")
model = T5ForConditionalGeneration.from_pretrained("unicamp-dl/ptt5-v2-3b")
