How to run

Shell

pip install transformers sentencepiece torch

Python

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

# This repository keeps its weights in a subfolder.
repo, sub = "WindyTranslate/translate-af-es", "herm0"
tok = AutoTokenizer.from_pretrained(repo, subfolder=sub)
model = AutoModelForSeq2SeqLM.from_pretrained(repo, subfolder=sub)

batch = tok(["<Afrikaans text>"], return_tensors="pt", padding=True)
print(tok.batch_decode(model.generate(**batch), skip_special_tokens=True)[0])

Tested: Pattern run on 2026-10-01 against WindyTranslate/translate-af-de (subfolder "lora") with transformers 5.18.0 on CPU. Not run on every model individually.
