torch_is_nonzero {torch}

Is_nonzero

Description

Is_nonzero

Usage

torch_is_nonzero(self)

Arguments

self

(Tensor) the input tensor.

is_nonzero(input) -> (bool)

Returns TRUE if the input is a single element tensor which is not equal to zero after type conversions. i.e. not equal to torch_tensor(c(0)) or torch_tensor(c(0)) or torch_tensor(c(FALSE)). Throws a RuntimeError if torch_numel() != 1 (even in case of sparse tensors).

Examples

if (torch_is_installed()) {

torch_is_nonzero(torch_tensor(c(0.)))
torch_is_nonzero(torch_tensor(c(1.5)))
torch_is_nonzero(torch_tensor(c(FALSE)))
torch_is_nonzero(torch_tensor(c(3)))
if (FALSE) {
torch_is_nonzero(torch_tensor(c(1, 3, 5)))
torch_is_nonzero(torch_tensor(c()))
}
}
