🚀 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) )
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."))
