Usage

This repository uses the standard Transformers Marian layout, so you can load it directly:

from transformers import MarianMTModel, MarianTokenizer

tokenizer = MarianTokenizer.from_pretrained("your-user/en-ckb-marian")
model = MarianMTModel.from_pretrained("your-user/en-ckb-marian")

inputs = tokenizer("Hello world", return_tensors="pt")
generated = model.generate(**inputs)
print(tokenizer.decode(generated[0], skip_special_tokens=True))

Notes

• The weights were converted from the local Marian checkpoint into the Hugging Face MarianMTModel format.
• Review dataset and license compatibility before redistributing the model publicly.
