Function sum

tensorflow/python/keras/backend.py:1883–1897

Sum of the values in a tensor, alongside the specified axis. Arguments: x: A tensor or variable. axis: An integer, the axis to sum over. keepdims: A boolean, whether to keep the dimensions or not. If `keepdims` is `False`, the rank of the tensor is reduced by

(x, axis=None, keepdims=False)
