HPLT/translate-en-nn-v2.0-hplt_opus

HPLT MT release v2.0

This repository contains the English-Norwegian Nynorsk (en->nn) encoder-decoder translation model trained on HPLT v2.0 and OPUS parallel data. The model is currently available in Marian format and we are working on converting it to the Hugging Face format.

Model Info

• Source language: English
• Target language: Norwegian Nynorsk
• Data: HPLT v2.0 and OPUS parallel data
• Model architecture: Transformer-base
• Tokenizer: SentencePiece (Unigram)

You can check out our paper, GitHub repository, or website for more details.

Usage

The model has been trained with MarianNMT and the weights are in the Marian format.

Using Marian

To run inference with MarianNMT, refer to the Inference/Decoding/Translation section of our GitHub repository. You will need the model file model.npz.best-chrf.npz and the vocabulary file model.en-nn.spm from this repository.

Using transformers

We are working on this.
