## Example usage
This model currently needs a custom wrapper from `modeling_nort5.py`. Then you can use it like this:
```python
import torch
from transformers import AutoTokenizer
from modeling_norbert import NorT5ForConditionalGeneration
tokenizer = AutoTokenizer.from_pretrained("path/to/folder")
t5 = NorT5ForConditionalGeneration.from_pretrained("path/to/folder")
# MASKED LANGUAGE MODELING
sentence = "Brukseksempel: Elektrisk oppvarming. Definisjonen på ordet oppvarming er[MASK_0]."
encoding = tokenizer(sentence)
input_tensor = torch.tensor([encoding.input_ids])
output_tensor = model.generate(input_tensor, decoder_start_token_id=7, eos_token_id=8)
tokenizer.decode(output_tensor.squeeze(), skip_special_tokens=True)
# should output: å varme opp
# PREFIX LANGUAGE MODELING
# you need to finetune this model or use `nort5-{size}-lm` model, which is finetuned on prefix language modeling
sentence = "Brukseksempel: Elektrisk oppvarming. Definisjonen på ordet oppvarming er (Wikipedia) "
encoding = tokenizer(sentence)
input_tensor = torch.tensor([encoding.input_ids])
output_tensor = model.generate(input_tensor, max_new_tokens=50, num_beams=4, do_sample=False)
tokenizer.decode(output_tensor.squeeze())
# should output: [BOS]ˈoppvarming, det vil si at det skjer en endring i temperaturen i et medium, f.eks. en ovn eller en radiator, slik at den blir varmere eller kaldere, eller at den blir varmere eller kaldere, eller at den blir
