R tensors into a rank R+1 tensor.Stacks a list of rank R tensors into a rank R+1 tensor.
k_stack(x, axis = 1)A tensor.
List of tensors.
Axis along which to perform stacking (axis indexes are 1-based).
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.).
