opus-mt-tc-big-zle-gmq

Neural machine translation model for translating from East Slavic languages (zle) to North Germanic languages (gmq).

This model is part of the OPUS-MT project, 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, 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 and training pipelines use the procedures of OPUS-MT-train.

Model info

Release: 2022-03-14
source language(s): rus ukr
target language(s): dan nob nor swe
valid target language labels: >>dan<< >>nob<< >>nor<< >>swe<<
model: transformer-big
data: opusTCv20210807+pft (source)
tokenization: SentencePiece (spm32k,spm32k)
original model: opusTCv20210807+pft_transformer-big_2022-03-14.zip
more information released models: OPUS-MT zle-gmq README
more information about the model: MarianMT

This is a multilingual translation model with multiple target languages. A sentence initial language token is required in the form of >>id<< (id = valid target language ID), e.g. >>dan<<

Usage

A short example code:

python

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    ">>dan<< Заўтра ўжо чацвер.",
    ">>swe<< Том грав з Мері в кішки-мишки."
]

model_name = "pytorch-models/opus-mt-tc-big-zle-gmq"
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:
#     I morgen er det torsdag.
#     Tom lekte med Mary i katt-möss.

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-zle-gmq")
print(pipe(">>dan<< Заўтра ўжо чацвер."))

# expected output: I morgen er det torsdag.
