opus-mt-tc-big-zlw-zle
Neural machine translation model for translating from West Slavic languages (zlw) to East Slavic languages (zle).
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: 2022-03-19
- source language(s): ces dsb hsb pol
- target language(s): bel rus ukr
- valid target language labels: >>bel<< >>rus<< >>ukr<<
- model: transformer-big
- data: opusTCv20210807+bt (source)
- tokenization: SentencePiece (spm32k,spm32k)
- original model: opusTCv20210807+bt_transformer-big_2022-03-19.zip
- more information released models: OPUS-MT zlw-zle 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. >>bel<<
Usage
A short example code:
from transformers import MarianMTModel, MarianTokenizer
src_text = [
">>rus<< Je vystudovaný právník.",
">>rus<< Gdzie jest moja książka ?"
]
model_name = "pytorch-models/opus-mt-tc-big-zlw-zle"
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:
# Он дипломированный юрист.
# Где моя книга?
You can also use OPUS-MT models with the transformers pipelines, for example:
from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-zlw-zle")
print(pipe(">>rus<< Je vystudovaný právník."))
# expected output: Он дипломированный юрист.
