input
, this operation inserts a dimension of 1 at the
dimension index axis
of input
's shape. The dimension index axis
starts at
zero; if you specify a negative number for axis
it is counted backward from
the end.
This operation is useful if you want to add a batch dimension to a single
element. For example, if you have a single image of shape [height, width,
channels]
, you can make it a batch of 1 image with expand_dims(image, 0)
,
which will make the shape [1, height, width, channels]
.
Other examples:
# 't' is a tensor of shape [2]
shape(expand_dims(t, 0)) ==> [1, 2]
shape(expand_dims(t, 1)) ==> [2, 1]
shape(expand_dims(t, -1)) ==> [2, 1]
# 't2' is a tensor of shape [2, 3, 5]
shape(expand_dims(t2, 0)) ==> [1, 2, 3, 5]
shape(expand_dims(t2, 2)) ==> [2, 3, 1, 5]
shape(expand_dims(t2, 3)) ==> [2, 3, 5, 1]
This operation requires that:
-1-input.dims() <= dim <= input.dims()
This operation is related to squeeze()
, which removes dimensions of
size 1.
Arguments:
* scope: A Scope object
* axis: 0-D (scalar). Specifies the dimension index at which to
expand the shape of input
. Must be in the range
[-rank(input) - 1, rank(input)]
.
Returns:
* Output
: Contains the same data as input
, but its shape has an additional
dimension of size 1 added.Pointer.CustomDeallocator, Pointer.Deallocator, Pointer.NativeDeallocator, Pointer.ReferenceCounter
