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

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.).
