| # Original: M2M100 418M | |
| M2M100 is a multilingual encoder-decoder (seq-to-seq) model trained for Many-to-Many multilingual translation. | |
| It was introduced in this [paper](https://arxiv.org/abs/2010.11125) and first released in [this](https://github.com/pytorch/fairseq/tree/master/examples/m2m_100) repository. | |
| The model that can directly translate between the 9,900 directions of 100 languages. | |
| To translate into a target language, the target language id is forced as the first generated token. | |
| To force the target language id as the first generated token, pass the `forced_bos_token_id` parameter to the `generate` method. | |
| *Note: `M2M100Tokenizer` depends on `sentencepiece`, so make sure to install it before running the example.* | |
| To install `sentencepiece` run `pip install sentencepiece` | |
| ```python | |
| 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("facebook/m2m100_418M") | |
| tokenizer = M2M100Tokenizer.from_pretrained("facebook/m2m100_418M") | |
| # 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 box of chocolate." | |
| ``` | |
