Packs a list of `N` rank-`R` tensors into one rank-`(R+1)` tensor.
Packs the `N` tensors in `values` into a tensor with rank one higher than each
tensor in `values`, by packing them along the `axis` dimension.
Given a list of tensors of shape `(A, B, C)`;
if `axis == 0` then the `output` tensor will have the shape `(N, A, B, C)`.
if `axis == 1` then the `output` tensor will have the shape `(A, N, B, C)`.
Etc.
For example:
# 'x' is [1, 4]
# 'y' is [2, 5]
# 'z' is [3, 6]
pack([x, y, z]) => [[1, 4], [2, 5], [3, 6]] # Pack along first dim.
pack([x, y, z], axis=1) => [[1, 2, 3], [4, 5, 6]]
This is the opposite of `unpack`.

Public Methods
public
Output<T>
asOutput
()
Returns the symbolic handle of a tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is
used to obtain a symbolic handle that represents the computation of the input.
public
static
Stack.Options
axis
(Long axis)
Parameters
axis |
Dimension along which to pack. Negative values wrap around, so the
valid range is `[-(R+1), R+1)`.
|
public
static
Stack<T>
create
(Scope scope, Iterable<Operand<T>> values, Options... options)
Factory method to create a class wrapping a new Stack operation.
Parameters
scope |
current scope |
values |
Must be of same shape and type. |
options |
carries optional attributes values |
