Sum of the values in a tensor, alongside the specified axis.

k_sum(x, axis = NULL, keepdims = FALSE)

Arguments

x	A tensor or variable.
axis	An integer, the axis to sum over (axis indexes are 1-based).
keepdims	A boolean, whether to keep the dimensions or not. If `keepdims` is `FALSE`, the rank of the tensor is reduced by 1. If `keepdims` is `TRUE`, the reduced dimension is retained with length 1.

Value

A tensor with sum of x.

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.).
