returned Tensor. Default: "torch.strided".
  * **pin_memory** (*bool**, **optional*) -- If set, returned
    tensor would be allocated in the pinned memory. Works only for
    CPU tensors. Default: "False".

Example:
  >>> tensor = torch.ones(())
  >>> tensor.new_empty((2, 3))
  tensor([[ 5.8182e-18,  4.5765e-41, -1.0545e+30],
          [ 3.0949e-41,  4.4842e-44,  0.0000e+00]])
