Unstack

Save and categorize content based on your preferences.
Unpacks a given dimension of a rank-`R` tensor into `num` rank-`(R-1)` tensors.
Unpacks `num` tensors from `value` by chipping it along the `axis` dimension.
For example, given a tensor of shape `(A, B, C, D)`;
If `axis == 0` then the i'th tensor in `output` is the slice `value[i, :, :, :]`
and each tensor in `output` will have shape `(B, C, D)`. (Note that the
dimension unpacked along is gone, unlike `split`).
If `axis == 1` then the i'th tensor in `output` is the slice `value[:, i, :, :]`
and each tensor in `output` will have shape `(A, C, D)`.
Etc.
This is the opposite of `pack`.

Parameters
| axis |
Dimension along which to unpack. Negative values wrap around, so the
valid range is `[-R, R)`.

Unstack<T>
create
(Scope scope, Operand<T> value, Long num, Options... options)
Factory method to create a class wrapping a new Unstack operation.
Parameters
| scope |
current scope |
| value |
1-D or higher, with `axis` dimension size equal to `num`. |
| options |
carries optional attributes values |
Returns
- a new instance of Unstack
