Retrieves the elements of indices `indices`

in the tensor `reference`

.

k_gather(reference, indices)

## Arguments

reference |
A tensor. |

indices |
Indices. Dimension indices are 1-based. Note however that if you pass a
tensor for `indices` they will be passed as-is, in which case indices will be 0 based
because no normalizing of R 1-based axes to Python 0-based axes is performed. |

## Value

A tensor of same type as `reference`

.

## Keras Backend

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.).
