Constructs a tensor with no autograd history (also known as a “leaf tensor”, see Autograd mechanics) by copying data. When working with tensors prefer using torch.Tensor.clone(),

Investigating why a model implementation using SDPA vs no SDPA was not yielding the exact same output using fp16 with the math backend, I pinned it down to a different
