Compute the cumulative sum of the tensor `x` along `axis`.
By default, this op performs an inclusive cumsum, which means that the first element of the input is identical to the first element of the output:
tf.cumsum([a, b, c]) # => [a, a + b, a + b + c]
tf.cumsum([a, b, c], exclusive=True) # => [0, a, a + b]
tf.cumsum([a, b, c], reverse=True) # => [a + b + c, b + c, c]
tf.reverse
ops.
The `reverse` and `exclusive` kwargs can also be combined:
tf.cumsum([a, b, c], exclusive=True, reverse=True) # => [b + c, c, 0]

Inherited Methods
Constants
public static final String OP_NAME
The name of this op, as known by TensorFlow core engine
Public Methods
public Output<T> asOutput ()
Returns the symbolic handle of the tensor.
Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.
public static Cumsum<T> create (Scope scope, Operand<T> x, Operand<? extends TNumber> axis, Options... options)
Factory method to create a class wrapping a new Cumsum operation.
Parameters
scope | current scope |
---|---|
x | A `Tensor`. Must be one of the following types: `float32`, `float64`, `int64`, `int32`, `uint8`, `uint16`, `int16`, `int8`, `complex64`, `complex128`, `qint8`, `quint8`, `qint32`, `half`. |
axis | A `Tensor` of type `int32` (default: 0). Must be in the range `[-rank(x), rank(x))`. |
options | carries optional attributes values |
Returns
- a new instance of Cumsum
public static Cumsum.Options exclusive (Boolean exclusive)
Parameters
exclusive | If `True`, perform exclusive cumsum. |
---|
public static Cumsum.Options reverse (Boolean reverse)
Parameters
reverse | A `bool` (default: False). |
