Opus Mt Tc Big En El

🚀 opus-mt-tc-big-en-el

A neural machine translation model designed to translate from English (en) to Modern Greek (1453-) (el).

This model is part of the OPUS-MT project, an initiative aimed at making neural machine translation models widely available and accessible for numerous languages worldwide. All models are initially trained using the outstanding Marian NMT framework, an efficient NMT implementation written in pure C++. These models have been converted to pyTorch using the transformers library by huggingface. The training data is sourced from OPUS, and the training pipelines follow the procedures of OPUS-MT-train.

Usage

Basic Usage

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    "If I weren't broke, I'd buy it.",
    "I received your telegram."
]

model_name = "pytorch-models/opus-mt-tc-big-en-el"
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:
#     Αν δεν ήμουν άφραγκος, θα το αγόραζα.
#     Έλαβα το τηλεγράφημα σου.

Advanced Usage

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-en-el")
print(pipe("If I weren't broke, I'd buy it."))

# expected output: Αν δεν ήμουν άφραγκος, θα το αγόραζα.
