# opus-mt-tc-big-en-zle |
|
|
|
Neural machine translation model for translating from English (en) 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: 2022-03-13 |
|
* source language(s): eng |
|
* target language(s): bel rus ukr |
|
* valid target language labels: >>bel<< >>rus<< >>ukr<< |
|
* model: transformer-big |
|
* data: opusTCv20210807+bt ([source](https://github.com/Helsinki-NLP/Tatoeba-Challenge)) |
|

|
* more information released models: [OPUS-MT eng-zle README](https://github.com/Helsinki-NLP/Tatoeba-Challenge/tree/master/models/eng-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 = [ |
|
">>rus<< Are they coming as well?", |
|
">>rus<< I didn't let Tom do what he wanted to do." |
|
] |
|
|
|
model_name = "pytorch-models/opus-mt-tc-big-en-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: |
|
# Они тоже приедут? |
|
# Я не позволил Тому сделать то, что он хотел. |
|
``` |
|
|
|
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-zle") |
|
print(pipe(">>rus<< Are they coming as well?")) |
|
|
|
# expected output: Они тоже приедут? |
|
``` |
|
|
|
