opus-mt-tc-big-en-ces_slk

Neural machine translation model for translating from English (en) to Czech and Slovak (ces+slk).

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.

Model info

Usage

A short example code:

from transformers import MarianMTModel, MarianTokenizer

src_text = [
    ">>ces<< We were enemies.",
    ">>ces<< Do you think Tom knows what's going on?"
]

model_name = "pytorch-models/opus-mt-tc-big-en-ces_slk"
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:
#     Byli jsme nepřátelé.
#     Myslíš, že Tom ví, co se děje?

You can also use OPUS-MT models with the transformers pipelines, for example:

from transformers import pipeline
pipe = pipeline("translation", model="Helsinki-NLP/opus-mt-tc-big-en-ces_slk")
print(pipe(">>ces<< We were enemies."))

# expected output: Byli jsme nepřátelé.
