	# opus-mt-tc-big-de-zle

	Neural machine translation model for translating from German (de) to East Slavic languages (zle).

	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).

	## Model info

	* Release: 2022-03-23
	* source language(s): deu
	* target language(s): bel rus ukr
	* valid target language labels: >>bel<< >>rus<< >>ukr<<
	* model: transformer-big
	* data: opusTCv20210807 ([source](https://github.com/Helsinki-NLP/Tatoeba-Challenge))
	* tokenization: SentencePiece (spm32k,spm32k)
	* original model: [opusTCv20210807_transformer-big_2022-03-23.zip](https://object.pouta.csc.fi/Tatoeba-MT-models/deu-zle/opusTCv20210807_transformer-big_2022-03-23.zip)
	* more information released models: [OPUS-MT deu-zle README](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/models/deu-zle/README.md)
	* more information about the model: [MarianMT](https://huggingface.co/docs/transformers/model_doc/marian)

	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:

	```python
	from transformers import MarianMTModel, MarianTokenizer

	src_text = [
	">>ukr<< Der Soldat hat mir Wasser gegeben.",
	">>ukr<< Ich will hier nicht essen."
	]

	model_name = "pytorch-models/opus-mt-tc-big-de-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:
	# Солдат дав мені воду.
	# Я не хочу тут їсти.
	```

	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-de-zle")
	print(pipe(">>ukr<< Der Soldat hat mir Wasser gegeben."))

	# expected output: Солдат дав мені воду.
	```
