torch_count_nonzero.RdCount_nonzero
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)
}
