marian-mt is a neural machine translation model. In this example it is used to translate text from French to English. See the associated model card for details on the model itself.

Running an example

cargo run --example marian-mt --release -- \
    --text "Demain, dès l'aube, à l'heure où blanchit la campagne, Je partirai. Vois-tu, je sais que tu m'attends. J'irai par la forêt, j'irai par la montagne. Je ne puis demeurer loin de toi plus longtemps."

<NIL> Tomorrow, at dawn, at the time when the country is whitening, I will go. See,
I know you are waiting for me. I will go through the forest, I will go through the
mountain. I cannot stay far from you any longer.</s>

Generating the tokenizer.json files

You can use the following script to generate the tokenizer.json config files from the hf-hub repos. This requires the tokenizers and sentencepiece packages to be install and use the convert_slow_tokenizer.py script from this directory.

from convert_slow_tokenizer import MarianConverter
from transformers import AutoTokenizer


tokenizer = AutoTokenizer.from_pretrained("Helsinki-NLP/opus-mt-fr-en", use_fast=False)
fast_tokenizer = MarianConverter(tokenizer, index=0).converted()
fast_tokenizer.save(f"tokenizer-marian-base-fr.json")
fast_tokenizer = MarianConverter(tokenizer, index=1).converted()
fast_tokenizer.save(f"tokenizer-marian-base-en.json")
