This is a many-to-many model for translation into and out of Creole languages, trained from scratch on public data.

from transformers import MBartForConditionalGeneration, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("jhu-clsp/kreyol-mt-scratch-pubtrain", do_lower_case=False, use_fast=False, keep_accents=True)

# The tokenizer we use is based on the AlbertTokenizer class which is essentially sentencepiece. We train this sentencepeice model from scratch.
# Or use tokenizer = AlbertTokenizer.from_pretrained("jhu-clsp/kreyol-mt-scratch-pubtrain", do_lower_case=False, use_fast=False, keep_accents=True)

model = AutoModelForSeq2SeqLM.from_pretrained("jhu-clsp/kreyol-mt-scratch-pubtrain")

# Or use model = MBartForConditionalGeneration.from_pretrained("jhu-clsp/kreyol-mt-scratch-pubtrain")

# Some initial mapping
bos_id = tokenizer._convert_token_to_id_with_added_voc("<s>")
eos_id = tokenizer._convert_token_to_id_with_added_voc("</s>")
pad_id = tokenizer._convert_token_to_id_with_added_voc("<pad>")

# First tokenize the input and outputs. The format below is how the model was trained so the input should be "Sentence </s> <2hwc>". Similarly, the output should be "<2eng> Sentence </s>".
# Example: For Saint Lucian Patois to English translation, we need to use language indicator tags: <2acf> and <2eng> where acf represents Saint Lucian Patois and eng represents English.
# The following language indicator tokens are usable: <2acf>, <2aoa>, <2ara>, <2aze>, <2bah>, <2brc>, <2bzj>, <2bzk>, <2cab>, <2ceb>, <2cri>, <2crs>, <2dcr>, <2deu>, <2djk>, <2eng>, <2fab>, <2fng>, <2fpe>, <2fra>, <2gcf>, <2gcr>, <2gpe>, <2gul>, <2gyn>, <2hat>, <2icr>, <2jam>, <2kea>, <2kri>, <2ktu>, <2lou>, <2mart1259>, <2mfe>, <2mue>, <2nep>, <2pap>, <2pcm>, <2por>, <2pov>, <2pre>, <2rcf>, <2sag>, <2spa>, <2srm>, <2srn>, <2svc>, <2tpi>, <2trf>, <2wes>, <2zho>
