 The implementation is framework agnostic, and will work for PyTorch and TensorFlow models. If we have saved this in
-a file named `pair_classification.py`, we can then import it and register it like this.

 Once this is done, we can use it with a pretrained model. For instance `sgugger/finetuned-bert-mrpc` has been
 fine-tuned on the MRPC dataset, which classifies pairs of sentences as paraphrases or not.
