Max
Description
Max
Arguments
self |
(Tensor) the input tensor. |
dim |
(int) the dimension to reduce. |
keepdim |
(bool) whether the output tensor has |
out |
(tuple, optional) the result tuple of two output tensors (max, max_indices) |
other |
(Tensor) the second input tensor |
max(input) -> Tensor
Returns the maximum value of all elements in the input
tensor.
max(input, dim, keepdim=False, out=NULL) -> (Tensor, LongTensor)
Returns a namedtuple (values, indices)
where values
is the maximum
value of each row of the input
tensor in the given dimension
dim
. And indices
is the index location of each maximum value found
(argmax).
Warning
indices
does not necessarily contain the first occurrence of each
maximal value found, unless it is unique.
The exact implementation details are device-specific.
Do not expect the same result when run on CPU and GPU in general.
If keepdim
is TRUE
, the output tensors are of the same size
as input
except in the dimension dim
where they are of size 1.
Otherwise, dim
is squeezed (see torch_squeeze
), resulting
in the output tensors having 1 fewer dimension than input
.
max(input, other, out=NULL) -> Tensor
Each element of the tensor input
is compared with the corresponding
element of the tensor other
and an element-wise maximum is taken.
The shapes of input
and other
don't need to match,
but they must be broadcastable .
\mbox{out}_i = \max(\mbox{tensor}_i, \mbox{other}_i)
Note
When the shapes do not match, the shape of the returned output tensor follows the broadcasting rules .
Examples
if (torch_is_installed()) {
a = torch_randn(c(1, 3))
a
torch_max(a)
a = torch_randn(c(4, 4))
a
torch_max(a, dim = 1)
a = torch_randn(c(4))
a
b = torch_randn(c(4))
b
torch_max(a, other = b)
}
