# opus-mt-tc-base-fi-uk
Neural machine translation model for translating from Finnish (fi) to Ukrainian (uk).
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).

## Usage
A short example code:
```python
from transformers import MarianMTModel, MarianTokenizer
src_text = [
"Afrikka on ihmiskunnan kehto.",
"Yksi, kaksi, kolme, neljä, viisi, kuusi, seitsemän, kahdeksan, yhdeksän, kymmenen."
]
model_name = "pytorch-models/opus-mt-tc-base-fi-uk"
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:
# Африка є колискою людства.
# Один, два, три, чотири, п'ять, шість, сім, вісім, дев'ять, десять.
```
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-base-fi-uk")
print(pipe("Afrikka on ihmiskunnan kehto."))
# expected output: Африка є колискою людства.
```
