神经机器翻译模型,用于将英语(en)翻译为保加利亚语(bg)。
该模型是 OPUS-MT project 的一部分,旨在为世界上的许多语言提供广泛可用和可访问的神经机器翻译模型。所有模型最初都使用了炫人的 Marian NMT 框架进行训练,这是一个使用纯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。训练数据取自 OPUS ,训练流程使用了 OPUS-MT-train 的过程。

 简短的示例代码:
from transformers import MarianMTModel, MarianTokenizer
src_text = [
    "2001 is the year when the 21st century begins.",
    "This is Copacabana!"
]
model_name = "pytorch-models/opus-mt-tc-big-en-bg"
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:
#     2001 е годината, в която започва 21-ви век.
#     Това е Копакабана!
 您也可以使用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-en-bg")
print(pipe("2001 is the year when the 21st century begins."))
# expected output: 2001 е годината, в която започва 21-ви век.
