tensors.Unstack rank `R`

tensor into a list of rank `R-1`

tensors.

`k_unstack(x, axis = 1L, num = NULL, name = NULL)`

A tensor.

- x
a tensor.

- axis
Axis along which to perform stacking (axis indexes are 1-based). Negative values wrap around, so the valid range is

`[R, -R]`

.- num
An int. The length of the dimension axis. Automatically inferred if NULL (the default).

- name
A name for the operation (optional).

This function is part of a set of Keras backend functions that enable lower level access to the core operations of the backend tensor engine (e.g. TensorFlow, CNTK, Theano, etc.).
