Use torch.library.register_fake instead of deprecated torch.library.impl_abstract

[NicolasHug]

That was throwing the following warning:

  /home/nicolashug/.miniconda3/envs/pt/lib/python3.9/site-packages/torch/_custom_ops.py:253: DeprecationWarning: torch.library.impl_abstract was renamed to torch.library.register_fake. Please use that instead; we will remove torch.library.impl_abstract in a future version of PyTorch.
