Where

Usage

torch_where(condition, self = NULL, other = NULL)

Arguments

condition

(BoolTensor) When TRUE (nonzero), yield x, otherwise yield y

self

(Tensor) values selected at indices where condition is TRUE

other

(Tensor) values selected at indices where condition is FALSE

Note

The tensors `condition`, `x`, `y` must be broadcastable .

See also torch_nonzero().

where(condition, x, y) -> Tensor

Return a tensor of elements selected from either x or y, depending on condition.

The operation is defined as:

$${\text{out}}_i=\{\begin{array}{ll}{\text{x}}_i& \text{if }{\text{condition}}_i\\ {\text{y}}_i& \text{otherwise}\end{array}$$

where(condition) -> tuple of LongTensor

torch_where(condition) is identical to torch_nonzero(condition, as_tuple=TRUE).

Examples

if (torch_is_installed()) {

if (FALSE) { # \dontrun{
x = torch_randn(c(3, 2))
y = torch_ones(c(3, 2))
x
torch_where(x > 0, x, y)
} # }
