Opus Mt Tc Big Zh Ja

🚀 opus-mt-tc-big-zh-ja

A neural machine translation model for translating from Chinese (zh) to Japanese (ja).

🚀 Quick Start

This is a neural machine translation model designed to translate from Chinese to Japanese. It's part of the OPUS - MT project, aiming to make NMT models accessible for various languages.

Here is a simple example to get you started:

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    "生日快乐，Muiriel！",
    "好凍。"
]

model_name = "pytorch-models/opus-mt-tc-big-zh-ja"
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:
#     誕生日おめでとう、Muiriel!
#     寒い。

You can also use it with the transformers pipelines:

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-zh-ja")
print(pipe("生日快乐，Muiriel！"))

# expected output: 誕生日おめでとう、Muiriel!

✨ Features

• Multilingual Accessibility: Part of the OPUS - MT project, making neural machine translation available for many languages.
• Efficient Training: Originally trained using the Marian NMT framework, an efficient NMT implementation in pure C++.
• PyTorch Compatibility: Converted to pyTorch using the transformers library by huggingface.

📚 Documentation

Model Details

Neural machine translation model for translating from Chinese (zh) to Japanese (ja).

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.
