How to use?

import ctranslate2
from transformers import AutoTokenizer
from huggingface_hub import snapshot_download

REPO_ID = "pulkitchowdry/nllb-600m-ct2-int8"

# Download model from Hugging Face
model_dir = snapshot_download(repo_id=REPO_ID)

print("Model downloaded to:", model_dir)

# Load translator
translator = ctranslate2.Translator(

# Load tokenizer

# Tokenize
input_ids = tokenizer(text).input_ids

# Translate
results = translator.translate_batch(
