Hi @NripeshN 

Would this new `is_torch_mps_available` be used somewhere in `transformers`? Currently, this PR only adds the definition but not using it anywhere.

I was planning on creating a new pull request where I'd be using this function in transformers. This function would provide GPU acceleration for apple silicon Macs. 


Hi @ydshieh,
I have used is_torch_mps_available in the latest push
