Repeats the elements of a tensor along an axis.
x has shape
(s1, s2, s3) and
2, the output
will have shape
(s1, s2 * rep, s3).
k_repeat_elements(x, rep, axis)
Tensor or variable.
Integer, number of times to repeat.
Axis along which to repeat (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.).
