This model is part of the [OPUS-MT project](https://github.com/Helsinki-NLP/Opus-MT), an effort to make neural machine translation models widely available and accessible for many languages in the world. All models are originally trained using the amazing framework of [Marian NMT](https://marian-nmt.github.io/), an efficient NMT implementation written in pure C++. The models have been converted to pyTorch using the transformers library by huggingface. Training data is taken from [OPUS](https://opus.nlpl.eu/) and training pipelines use the procedures of [OPUS-MT-train](https://github.com/Helsinki-NLP/Opus-MT-train). * Publications: [OPUS-MT – Building open translation services for the World](https://aclanthology.org/2020.eamt-1.61/) and [The Tatoeba Translation Challenge – Realistic Data Sets for Low Resource and Multilingual MT](https://aclanthology.org/2020.wmt-1.139/) (Please, cite if you use this model.) ``` @inproceedings{tiedemann-thottingal-2020-opus, title = "{OPUS}-{MT} {--} Building open translation services for the World", author = {Tiedemann, J{\"o}rg and Thottingal, Santhosh}, booktitle = "Proceedings of the 22nd Annual Conference of the European Association for Machine Translation", month = nov, year = "2020", address = "Lisboa, Portugal", publisher = "European Association for Machine Translation", url = "https://aclanthology.org/2020.eamt-1.61", pages = "479--480", } @inproceedings{tiedemann-2020-tatoeba, title = "The Tatoeba Translation Challenge {--} Realistic Data Sets for Low Resource and Multilingual {MT}", author = {Tiedemann, J{\"o}rg}, booktitle = "Proceedings of the Fifth Conference on Machine Translation", month = nov, year = "2020", address = "Online", publisher = "Association for Computational Linguistics", url = "https://aclanthology.org/2020.wmt-1.139", pages = "1174--1182", } ``` ## Model info * Release: 2022-03-09 * source language(s): eng * target language(s): fra * model: transformer-big * data: opusTCv20210807+bt ([source](https://github.com/Helsinki-NLP/Tatoeba-Challenge)) * tokenization: SentencePiece (spm32k,spm32k) * original model: [opusTCv20210807+bt_transformer-big_2022-03-09.zip](https://object.pouta.csc.fi/Tatoeba-MT-models/eng-fra/opusTCv20210807+bt_transformer-big_2022-03-09.zip) * more information released models: [OPUS-MT eng-fra README](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/models/eng-fra/README.md) ## Usage A short example code: ```python from transformers import MarianMTModel, MarianTokenizer src_text = [ "The Portuguese teacher is very demanding.", "When was your last hearing test?" ] model_name = "pytorch-models/opus-mt-tc-big-en-fr" tokenizer = MarianTokenizer.from_pretrained(model_name) model = MarianMTModel.from_pretrained(model_name) translated = model.generate(**tokenizer(src_text, return_tensors="pt", padding=True)) for t in translated: print( tokenizer.decode(t, skip_special_tokens=True) ) # expected output: # Le professeur de portugais est très exigeant. # Quand a eu lieu votre dernier test auditif ? ``` You can also use OPUS-MT models with the transformers pipelines, for example: ```python from transformers import pipeline pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-en-fr") print(pipe("The Portuguese teacher is very demanding.")) # expected output: Le professeur de portugais est très exigeant. ``` ## Benchmarks * test set translations: [opusTCv20210807+bt_transformer-big_2022-03-09.test.txt](https://object.pouta.csc.fi/Tatoeba-MT-models/eng-fra/opusTCv20210807+bt_transformer-big_2022-03-09.test.txt) * test set scores: [opusTCv20210807+bt_transformer-big_2022-03-09.eval.txt](https://object.pouta.csc.fi/Tatoeba-MT-models/eng-fra/opusTCv20210807+bt_transformer-big_2022-03-09.eval.txt) * benchmark results: [benchmark_results.txt](benchmark_results.txt) * benchmark output: [benchmark_translations.zip](benchmark_translations.zip) | langpair | testset | chr-F | BLEU | #sent | #words | |----------|---------|-------|-------|-------|--------| | eng-fra | tatoeba-test-v2021-08-07 | 0.69621 | 53.2 | 12681 | 106378 | | eng-fra | flores101-devtest | 0.72494 | 52.2 | 1012 | 28343 | | eng-fra | multi30k_test_2016_flickr | 0.72361 | 52.4 | 1000 | 13505 | | eng-fra | multi30k_test_2017_flickr | 0.72826 | 52.8 | 1000 | 12118 | | eng-fra | multi30k_test_2017_mscoco | 0.73547 | 54.7 | 461 | 5484 | | eng-fra | multi30k_test_2018_flickr | 0.66723 | 43.7 | 1071 | 15867 | | eng-fra | newsdiscussdev2015 | 0.60471 | 33.4 | 1500 | 27940 | | eng-fra | newsdiscusstest2015 | 0.64915 | 40.3 | 1500 | 27975 | | eng-fra | newssyscomb2009 | 0.58903 | 30.7 | 502 | 12331 | | eng-fra | news-test2008 | 0.55516 | 27.6 | 2051 | 52685 | | eng-fra | newstest2009 | 0.57907 | 30.0 | 2525 | 69263 | | eng-fra | newstest2010 | 0.60156 | 33.5 | 2489 | 66022 | | eng-fra | newstest2011 | 0.61632 | 35.0 | 3003 | 80626 | | eng-fra | newstest2012 | 0.59736 | 32.8 | 3003 | 78011 | | eng-fra | newstest2013 | 0.59700 | 34.6 | 3000 | 70037 | | eng-fra | newstest2014 | 0.66686 | 41.9 | 3003 | 77306 | | eng-fra | tico19-test | 0.63022 | 40.6 | 2100 | 64661 | ## Acknowledgements The work is supported by the [European Language Grid](https://www.european-language-grid.eu/) as [pilot project 2866](https://live.european-language-grid.eu/catalogue/#/resource/projects/2866), by the [FoTran project](https://www.helsinki.fi/en/researchgroups/natural-language-understanding-with-cross-lingual-grounding), funded by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 771113), and the [MeMAD project](https://memad.eu/), funded by the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement No 780069.
