opus-mt-tc-big-el-en

神经机器翻译模型,用于将现代希腊语(1453年-)(el)翻译为英语(en)。

这个模型是 OPUS-MT project 的一部分,旨在为世界上许多语言提供广泛可用和易于访问的神经机器翻译模型。所有模型最初都是使用令人惊奇的 Marian NMT 框架进行训练的,该框架是用纯C++编写的高效NMT实现。模型已经使用huggingface的transformers库转换为pyTorch。训练数据取自 OPUS ,并且训练流程使用了 OPUS-MT-train 的流程。

模型信息

用法

简短的示例代码:

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    "Το σχολείο μας έχει εννιά τάξεις.",
    "Άρχισε να τρέχει."
]

model_name = "pytorch-models/opus-mt-tc-big-el-en"
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:
#     Our school has nine classes.
#     He started running.

您还可以使用transformers管道来使用OPUS-MT模型,例如:

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-el-en")
print(pipe("Το σχολείο μας έχει εννιά τάξεις."))

# expected output: Our school has nine classes.
