| # OPUS-MT-tiny-eng-nld |
|
|
| Distilled model from a Tatoeba-MT Teacher: [Tatoeba-MT-models/deu+eng+fra+por+spa-gmw/opusTCv20230926max50+bt+jhubc_transformer-big_2024-05-30](https://object.pouta.csc.fi/Tatoeba-MT-models/deu+eng+fra+por+spa-gmw/opusTCv20230926max50+bt+jhubc_transformer-big_2024-05-30.zip), which has been trained on the [Tatoeba](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/data) dataset. |
|
|
| We used the [OpusDistillery](https://github.com/Helsinki-NLP/OpusDistillery) to train new a new student with the tiny architecture, with a regular transformer decoder. |
| For training data, we used [Tatoeba](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/data). |
| The configuration file fed into OpusDistillery can be found [here](https://github.com/Helsinki-NLP/OpusDistillery/blob/main/configs/opustranslate_hf/config.op.en-nl.yml). |
|
|
| ## How to run |
| ```python |
| from transformers import MarianMTModel, MarianTokenizer |
| model_name = "Helsinki-NLP/opus-mt_tiny_eng-nld" |
| tokenizer = MarianTokenizer.from_pretrained(model_name) |
| model = MarianMTModel.from_pretrained(model_name) |
| tok = tokenizer("The area is also home to species of animals and birds with a wide variety.", return_tensors="pt").input_ids |
| output = model.generate(tok)[0] |
| tokenizer.decode(output, skip_special_tokens=True) |
| ``` |
|

|
| ## Marian models |
|
|
| We also provide Marian-compatible versions of this model. To use them, compile [Marian](https://marian-nmt.github.io/quickstart/) and run decoding with `marian-decoder`, for example: |
|
|
| ```bash |
| marian-decoder \ |
| -i input.txt \ |
| -c final.model.npz.best-perplexity.npz.decoder.yml \ |
| -m final.model.npz.best-perplexity.npz \ |
| -v vocab.spm vocab.spm |
