torch_count_nonzero {torch}

Count_nonzero

Description

Count_nonzero

Usage

torch_count_nonzero(self, dim = NULL)

Arguments

self

(Tensor) the input tensor.

dim

(int or tuple of ints, optional) Dim or tuple of dims along which to count non-zeros.

count_nonzero(input, dim=None) -> Tensor

Counts the number of non-zero values in the tensor input along the given dim. If no dim is specified then all non-zeros in the tensor are counted.

Examples

if (torch_is_installed()) {

x <- torch_zeros(3,3)
x[torch_randn(3,3) > 0.5] = 1
x
torch_count_nonzero(x)
torch_count_nonzero(x, dim=1)
}
