Flores101: Large-Scale Multilingual Machine Translation

flores101_mm100_175M is a multilingual encoder-decoder (seq-to-seq) model trained for Many-to-Many multilingual translation. It was released in this repository.

The model architecture and config are the same as M2M100 implementation, but the tokenizer should be modified to adjust language codes.

Demo: https://huggingface.co/spaces/seyoungsong/flores101_mm100_175M

from transformers import M2M100ForConditionalGeneration, M2M100Tokenizer

hi_text = "जीवन एक चॉकलेट बॉक्स की तरह है।"
chinese_text = "生活就像一盒巧克力。"

model = M2M100ForConditionalGeneration.from_pretrained("seyoungsong/flores101_mm100_175M")
tokenizer: M2M100Tokenizer = M2M100Tokenizer.from_pretrained("seyoungsong/flores101_mm100_175M")

# FIX TOKENIZER!
tokenizer.lang_token_to_id = {t: i for t, i in zip(tokenizer.all_special_tokens, tokenizer.all_special_ids) if i > 5}
tokenizer.lang_code_to_token = {s.strip("_"): s for s in tokenizer.lang_token_to_id}
tokenizer.lang_code_to_id = {s.strip("_"): i for s, i in tokenizer.lang_token_to_id.items()}
tokenizer.id_to_lang_token = {i: s for s, i in tokenizer.lang_token_to_id.items()}

# translate Hindi to French
tokenizer.src_lang = "hi"
encoded_hi = tokenizer(hi_text, return_tensors="pt")
generated_tokens = model.generate(**encoded_hi, forced_bos_token_id=tokenizer.get_lang_id("fr"))
tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
# => "La vie est comme une boîte de chocolat."

# translate Chinese to English
tokenizer.src_lang = "zh"
encoded_zh = tokenizer(chinese_text, return_tensors="pt")
generated_tokens = model.generate(**encoded_zh, forced_bos_token_id=tokenizer.get_lang_id("en"))
tokenizer.batch_decode(generated_tokens, skip_special_tokens=True)
# => "Life is like a chocolate box."
