OPUS-MT-tiny-nld-eng

Distilled model from a Tatoeba-MT Teacher: OPUS-MT-models/nl-en/opus-2019-12-05, which has been trained on the Tatoeba dataset.

We used the OpusDistillery to train new a new student with the tiny architecture, with a regular transformer decoder. For training data, we used Tatoeba. The configuration file fed into OpusDistillery can be found here.

How to run

python

>>> from transformers import MarianMTModel, MarianTokenizer
>>> model_name = "Helsinki-NLP/opus-mt_tiny_nld-eng"
>>> tokenizer = MarianTokenizer.from_pretrained(model_name)
>>> model = MarianMTModel.from_pretrained(model_name)
>>> tok = tokenizer("Hallo, hoe gaat het?", 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 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
