Usage

You can use this model with the transformers library like this:

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("sil-ai/madlad400-finetuned-onr_x_wol-tpi")
model = AutoModelForSeq2SeqLM.from_pretrained("sil-ai/madlad400-finetuned-onr_x_wol-tpi")

inputs = tokenizer("Your input text here", return_tensors="pt")
outputs = model.generate(**inputs)
print(tokenizer.decode(outputs[0]))
