torch_range {torch}

Range

Description

Range

Usage

torch_range(
  start,
  end,
  step = 1,
  dtype = NULL,
  layout = NULL,
  device = NULL,
  requires_grad = FALSE
)

Arguments

start

(float) the starting value for the set of points. Default: 0.

end

(float) the ending value for the set of points

step

(float) the gap between each pair of adjacent points. Default: 1.

dtype

(torch.dtype, optional) the desired data type of returned tensor. Default: if NULL, uses a global default (see torch_set_default_tensor_type). If dtype is not given, infer the data type from the other input arguments. If any of start, end, or stop are floating-point, the dtype is inferred to be the default dtype, see ~torch.get_default_dtype. Otherwise, the dtype is inferred to be torch.int64.

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.

range(start=0, end, step=1, out=NULL, dtype=NULL, layout=torch.strided, device=NULL, requires_grad=False) -> Tensor

Returns a 1-D tensor of size \left\lfloor \frac{\mbox{end} - \mbox{start}}{\mbox{step}} \right\rfloor + 1 with values from start to end with step step. Step is the gap between two values in the tensor.

\mbox{out}_{i+1} = \mbox{out}_i + \mbox{step}.

Warning

This function is deprecated in favor of torch_arange.

Examples

if (torch_is_installed()) {

torch_range(1, 4)
torch_range(1, 4, 0.5)
