tf.keras.backend.sum(
x,
axis=None,
keepdims=False
)
Defined in tensorflow/python/keras/backend.py
.
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. Ifkeepdims
isFalse
, the rank of the tensor is reduced by 1. Ifkeepdims
isTrue
, the reduced dimension is retained with length 1.
Returns:
A tensor with sum of x
.
