Returns a tensor filled with the scalar value 1, with the shape defined by the variable argument size.
Args: size (int...): a sequence of integers defining the shape of the output tensor. Can be a variable number of arguments or a collection like a listortuple.
Keyword arguments: out (Tensor, optional): the output tensor. dtype (torch.dtype, optional): the desired data type of returned tensor. Default: ifNone, uses a global default (see torch.set_default_tensor_type()). layout (torch.layout, optional): the desired layout of returned Tensor. Default: torch.strided. device (torch.device, optional): the desired device of returned tensor. Default: ifNone, uses the current device for the default tensor type (see torch.set_default_tensor_type()). device will be the CPU for CPU tensor types and the current CUDA device for CUDA tensor types. requires_grad (bool, optional): If autograd should record operations on the returned tensor. Default: False.
