torch_empty_strided

Empty_strided

Description

Empty_strided

Usage

torch_empty_strided(
  size,
  stride,
  dtype = NULL,
  layout = torch_strided(),
  device = NULL,
  requires_grad = FALSE,
  pin_memory = FALSE
)

Arguments

`size`	(tuple of ints) the shape of the output tensor
`stride`	(tuple of ints) the strides of the output tensor
`dtype`	(`torch.dtype`, optional) the desired data type of returned tensor. Default: if `NULL`, 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: if `NULL`, 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`.
`pin_memory`	(bool, optional) If set, returned tensor would be allocated in the pinned memory. Works only for CPU tensors. Default: `FALSE`.

empty_strided(size, stride, dtype=NULL, layout=NULL, device=NULL, requires_grad=False, pin_memory=False) -> Tensor

Returns a tensor filled with uninitialized data. The shape and strides of the tensor is defined by the variable argument size and stride respectively. torch_empty_strided(size, stride) is equivalent to torch_empty(size).as_strided(size, stride).

Warning

More than one element of the created tensor may refer to a single memory location. As a result, in-place operations (especially ones that are vectorized) may result in incorrect behavior. If you need to write to the tensors, please clone them first.

Examples

if (torch_is_installed()) {

a = torch_empty_strided(list(2, 3), list(1, 2))
a
a$stride(1)
a$size(1)
}
