Thank you @Marcin,
I had already tested it with Narrativa/mbart-large 1 the which produces the following result:
!pip install transformers

translator = pipeline(
    model="Narrativa/mbart-large-50-finetuned-opus-en-pt-translation", 
    task="translation_en_to_pt"
    )


translator("How old are you?", src_lang="en", tgt_lang="pt")
# [{'translation_text': 'pt - - - - - - - - - - - - - - - - - - - - - - - - - - 
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -'}]
