英文

opus-mt-tc-big-en-ro

神经机器翻译模型,用于将英语(en)翻译成罗马尼亚语(ro)。

该模型是 OPUS-MT project 的一部分,该项目旨在使神经机器翻译模型在世界上的许多语言中得到广泛使用和访问。所有模型都是使用 Marian NMT 的出色框架进行训练的, Marian NMT 是一个用纯C++编写的高效NMT实现。这些模型已经使用huggingface的transformers库将其转换为pyTorch。训练数据来自 OPUS ,并且训练流程使用了 OPUS-MT-train 的过程。

模型信息

用法

简短示例代码:

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    ">>ron<< A bad writer's prose is full of hackneyed phrases.",
    ">>ron<< Zero is a special number."
]

model_name = "pytorch-models/opus-mt-tc-big-en-ro"
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:
#     Proza unui scriitor prost este plină de fraze tocite.
#     Zero este un număr special.

您还可以使用transformers的pipelines来使用OPUS-MT模型,例如:

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-en-ro")
print(pipe(">>ron<< A bad writer's prose is full of hackneyed phrases."))

# expected output: Proza unui scriitor prost este plină de fraze tocite.
