# Retrieves the elements of indices <code>indices</code> in the tensor <code>reference</code>.

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.).
