## Hitz Center’s English-Basque machine translation model converted to CTranslate2

## Model description

- [Original model](https://huggingface.co/HiTZ/mt-hitz-en-eu)

# What is CTranslate2?
[CTranslate2](https://opennmt.net/CTranslate2/) is a C++ and Python library for efficient inference with Transformer models.

CTranslate2 implements a custom runtime that applies many performance optimization techniques such as weights quantization, layers fusion, batch reordering, etc., to accelerate and reduce the memory usage of Transformer models on CPU and GPU.

CTranslate2 is one of the most performant ways of hosting translation models at scale. Current supported models include:
- Encoder-decoder models: Transformer base/big, M2M-100, NLLB, BART, mBART, Pegasus, T5, Whisper
- Decoder-only models: GPT-2, GPT-J, GPT-NeoX, OPT, BLOOM, MPT, Llama, Mistral, Gemma, CodeGen, GPTBigCode, Falcon
- Encoder-only models: BERT, DistilBERT, XLM-RoBERTa

The project is production-oriented and comes with backward compatibility guarantees, but it also includes experimental features related to model compression and inference acceleration.

# Sample Code - ctranslate2
#### Clone the repository to the working directory or wherever you wish to store the model artifacts. ####
```bash
git clone https://huggingface.co/xezpeleta/mt-hitz-en-eu-ct2
```

#### Take the python code below and update the 'model_dir' variable to the location of the cloned repository. ####

```python
from ctranslate2 import Translator
import transformers

model_dir = "./mt-hitz-en-eu-ct2" # Path to model directory.
translator = Translator(
            model_path=model_dir,
            device="cuda", # cpu, cuda, or auto.
            inter_threads=1, # Maximum number of parallel translations.
            intra_threads=4, # Number of OpenMP threads per translator.
            compute_type="int8_float16", # int8 for cpu or int8_float16 for cuda.
)

tokenizer = transformers.AutoTokenizer.from_pretrained(model_dir)

source = tokenizer.convert_ids_to_tokens(tokenizer.encode("Hello, world!"))
results = translator.translate_batch([source])
target = results[0].hypotheses[0]

print(tokenizer.decode(tokenizer.convert_tokens_to_ids(target)))
```
