opus-mt-tc-big-en-fi

Neural machine translation model for translating from English (en) to Finnish (fi).

This model is part of the OPUS-MT project, 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, 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 and training pipelines use the procedures of OPUS-MT-train.

Model info

Release: 2022-03-09
source language(s): eng
target language(s): fin
valid target language labels: >>fin<<
model: transformer (big)
data: opusTCv20210807+bt (source)
tokenization: SentencePiece (spm32k,spm32k)
original model: opusTCv20210807+bt_transformer-big_2022-03-09.zip
more information released models: OPUS-MT eng-fin README
more information about the model: MarianMT

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. >>fin<<

Usage

A short example code:

python

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    "Russia is big.",
    "Touch wood!"
]

model_name = "pytorch-models/opus-mt-tc-big-en-fi"
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:
#     Venäjä on suuri.
#     Kosketa puuta!

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-fi")
print(pipe("Russia is big."))

# expected output: Venäjä on suuri.
