### Introduction

Catalan - German translation model for OpenNMT. These are the same models that we have in production at https://www.softcatala.org/traductor/.
The models are quantified for low latency.

### Usage

Install the necessary dependencies:


```bash
pip3 install ctranslate2 pyonmttok
```


Simple tokenization & translation using Python:


```python
import ctranslate2
import pyonmttok
from huggingface_hub import snapshot_download
model_dir = snapshot_download(repo_id="softcatala/translate-cat-deu", revision="main")

tokenizer=pyonmttok.Tokenizer(mode="none", sp_model_path = model_dir + "/sp_m.model")
tokenized=tokenizer.tokenize("Hola amics")

translator = ctranslate2.Translator(model_dir)
translated = translator.translate_batch([tokenized[0]])
print(tokenizer.detokenize(translated[0][0]['tokens']))
```
