Opus Mt Tc Big En Pt

🚀 opus-mt-tc-big-en-pt

A neural machine translation model designed to translate from English (en) to Portuguese (pt). This project aims to make neural machine translation models accessible for various languages.

🚀 Quick Start

This model is part of the OPUS-MT project, an initiative to make neural machine translation models widely available for numerous languages globally. All models are initially trained using the Marian NMT framework, an efficient NMT implementation in pure C++. The models are then converted to pyTorch using the transformers library by huggingface. Training data is sourced from OPUS, and training pipelines follow the procedures of OPUS-MT-train.

✨ Features

• Multilingual Support: This is a multilingual translation model with multiple target languages.
• Initial Language Token: A sentence initial language token in the form of >>id<< (id = valid target language ID) is required, e.g., >>pob<<.

💻 Usage Examples

Basic Usage

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    ">>por<< Tom tried to stab me.",
    ">>por<< He has been to Hawaii several times."
]

model_name = "pytorch-models/opus-mt-tc-big-en-pt"
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:
#     O Tom tentou esfaquear-me.
#     Ele já esteve no Havaí várias vezes.

Advanced Usage

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-en-pt")
print(pipe(">>por<< Tom tried to stab me."))

# expected output: O Tom tentou esfaquear-me.
