🛠️ Usage

from transformers import MarianMTModel, MarianTokenizer

# Load model and tokenizer
model_name = "dhintech/marian-ted2020-id-en-lg"
tokenizer = MarianTokenizer.from_pretrained(model_name)
model = MarianMTModel.from_pretrained(model_name)

# Translate Indonesian to English
def translate(text):
    inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True, max_length=128)
    outputs = model.generate(
        **inputs,
        max_length=128,
        num_beams=3,
        early_stopping=True,
        do_sample=False
    )
    return tokenizer.decode(outputs[0], skip_special_tokens=True)

# Example usage
indonesian_text = "Tim marketing akan bertanggung jawab untuk strategi ini."
english_translation = translate(indonesian_text)
print(english_translation)
# Output: "The marketing team will be responsible for this strategy."
