trying to make pow work for tensor raised to the power of a scalar (#46185)
Summary:
Fixes https://github.com/pytorch/pytorch/issues/46037
I'm not sure this is the most performant solution, but this works:
torch.pow(cuda_tensor, 5) should work and worked before.
torch.pow(cuda_tensor, torch.tensor(5)), should work **and works now!**
torch.pow(cuda_tensor, torch.tensor((5,))), should NOT work and complain the tensors are on different devices and indeed continues to complain.
