opus-mt-tc-big-ces_slk-en
Neural machine translation model for translating from Czech and Slovak (ces+slk) to English (en).
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.

Usage
A short example code:
from transformers import MarianMTModel, MarianTokenizer
src_text = [
"Podívej se na své kalhoty! Zapni si je na zip.",
"Mrzí mě, že Tom odchází."
]
model_name = "pytorch-models/opus-mt-tc-big-ces_slk-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:
# Look at your pants, zip them up.
# I'm sorry Tom's leaving.
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-ces_slk-en")
print(pipe("Podívej se na své kalhoty! Zapni si je na zip."))
# expected output: Look at your pants, zip them up.
