Model Description

This model is a fine-tuned version of nllb-200-distilled-600M, specifically adapted for English-Wolof and Wolof-English translation. It was trained using the sudoping01/english-wolof-translation dataset, which underwent significant preprocessing to enhance translation quality.

The model supports bidirectional translation:

• Wolof to English
• English to Wolof

How to Use

1. Inference Manually
Install the required library:

!pip install transformers

Python code for translation:

from transformers import NllbTokenizer, AutoModelForSeq2SeqLM
import torch

device = "cuda" if torch.cuda.is_available() else "cpu"
model_load_name = 'bilalfaye/nllb-200-distilled-600M-en-wo'

# Load model and tokenizer
model = AutoModelForSeq2SeqLM.from_pretrained(model_load_name).to(device)
tokenizer = NllbTokenizer.from_pretrained(model_load_name)

def translate(
    text, src_lang='wol_Latn', tgt_lang='eng_Latn',
    a=32, b=3, max_input_length=1024, num_beams=4, **kwargs
):
    """Turn a text or a list of texts into a list of translations"""
    tokenizer.src_lang = src_lang
    tokenizer.tgt_lang = tgt_lang
    inputs = tokenizer(
        text, return_tensors='pt', padding=True, truncation=True,
        max_length=max_input_length
    )
    model.eval()
    result = model.generate(
        **inputs.to(model.device),
        forced_bos_token_id=tokenizer.convert_tokens_to_ids(tgt_lang),
        max_new_tokens=int(a + b * inputs.input_ids.shape[1]),
        num_beams=num_beams, **kwargs
    )
    return tokenizer.batch_decode(result, skip_special_tokens=True)

# Example usage
print(translate("Ndax mën nga ko waxaat su la neexee?", src_lang="wol_Latn", tgt_lang="eng_Latn")[0])
print(translate("This gentleman will pay for everything", src_lang="eng_Latn", tgt_lang="wol_Latn")[0])

2. Inference with Pipeline
Install the required library:

!pip install transformers

Python code using the pipeline:

from transformers import pipeline

model_name = 'bilalfaye/nllb-200-distilled-600M-en-wo'
device = "cuda" if torch.cuda.is_available() else "cpu"

translator = pipeline("translation", model=model_name, device=device)

print(translator("Ndax mën nga ko waxaat su la neexee?", src_lang="wol_Latn", tgt_lang="eng_Latn")[0]['translation_text'])
print(translator("This gentleman will pay for everything", src_lang="eng_Latn", tgt_lang="wol_Latn")[0]['translation_text'])
