Nansum
Arguments
- self
(Tensor) the input tensor.
- dim
(int or tuple of ints) the dimension or dimensions to reduce.
- keepdim
(bool) whether the output tensor has
dim
retained or not.- dtype
the desired data type of returned tensor. If specified, the input tensor is casted to dtype before the operation is performed. This is useful for preventing data type overflows. Default:
NULL
.
nansum(input, *, dtype=None) -> Tensor
Returns the sum of all elements, treating Not a Numbers (NaNs) as zero.
nansum(input, dim, keepdim=FALSE, *, dtype=None) -> Tensor
Returns the sum of each row of the input
tensor in the given
dimension dim
, treating Not a Numbers (NaNs) as zero.
If dim
is a list of dimensions, reduce over all of them.
If keepdim
is TRUE
, the output tensor is of the same size
as input
except in the dimension(s) dim
where it is of size 1.
Otherwise, dim
is squeezed (see torch_squeeze
), resulting in the
output tensor having 1 (or len(dim)
) fewer dimension(s).
Examples
if (torch_is_installed()) {
a <- torch_tensor(c(1., 2., NaN, 4.))
torch_nansum(a)
torch_nansum(torch_tensor(c(1., NaN)))
a <- torch_tensor(rbind(c(1, 2), c(3., NaN)))
torch_nansum(a)
torch_nansum(a, dim=1)
torch_nansum(a, dim=2)
