NLLB-200 Distilled-350M_en2ko

The NLLB-200 model showed outstanding performance in translation task and contributed to solving problems with low-resource languages. Despite their efforts, it is still hard to run 600M or more than 1B model for those who have not enough computing environment. So I made much smaller model that expertized translaing English to Korean. you can also run it with cpu (No mixed-precision, No Quantization). [우당탕탕 개발일지]

Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

model = AutoModelForSeq2SeqLM.from_pretrained('dhtocks/nllb-200-distilled-350M_en-ko', forced_bos_token_id=256098)
tokenizer = AutoTokenizer.from_pretrained('dhtocks/nllb-200-distilled-350M_en-ko', src_lang='eng_Latn', tgt_lang='kor_Hang')

inputs = tokenizer('[YOUR_INPUT]', return_tensors="pt")
output = model.generate(**inputs)
print(tokenizer.decode(output[0]))
