| # NLLB-MoE | |
| This is the model card of NLLB-MoE variant. | |
| - Information about training algorithms, parameters, fairness constraints or other applied approaches, and features. The exact training algorithm, data and the strategies to handle data imbalances for high and low resource languages that were used to train NLLB-200 is described in the paper. | |

| ## Generating with NLLB-MoE | |
| The avalable checkpoints requires around 350GB of storage. Make sure to use `accelerate` if you do not have enough RAM on your machine. | |
| While generating the target text set the `forced_bos_token_id` to the target language id. The following | |
| example shows how to translate English to French using the *facebook/nllb-200-distilled-600M* model. | |
| Note that we're using the BCP-47 code for French `fra_Latn`. See [here](https://github.com/facebookresearch/flores/blob/main/flores200/README.md#languages-in-flores-200) | |
| for the list of all BCP-47 in the Flores 200 dataset. | |
| ```python | |
| >>> from transformers import AutoModelForSeq2SeqLM, AutoTokenizer | |
| >>> tokenizer = AutoTokenizer.from_pretrained("facebook/nllb-moe-54b") | |
| >>> model = AutoModelForSeq2SeqLM.from_pretrained("facebook/nllb-moe-54b") | |
| >>> article = "UN Chief says there is no military solution in Syria" | |
| >>> inputs = tokenizer(article, return_tensors="pt") | |
| >>> translated_tokens = model.generate( | |
| ... **inputs, forced_bos_token_id=tokenizer.lang_code_to_id["fra_Latn"], max_length=30 | |
| ... ) | |
| >>> tokenizer.batch_decode(translated_tokens, skip_special_tokens=True)[0] | |
| Le chef de l'ONU dit qu'il n'y a pas de solution militaire en Syrie | |
