[`tf.compat.v1.raw_ops.Cumsum`](https://www.tensorflow.org/api_docs/python/tf/raw_ops/Cumsum)

<br />

    tf.raw_ops.Cumsum(
        x, axis, exclusive=False, reverse=False, name=None
    )

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]

By setting the `exclusive` kwarg to `True`, an exclusive cumsum is
performed instead:

    tf.cumsum([a, b, c], exclusive=True)  # => [0, a, a + b]

By setting the `reverse` kwarg to `True`, the cumsum is performed in the
opposite direction:

    tf.cumsum([a, b, c], reverse=True)  # => [a + b + c, b + c, c]

This is more efficient than using separate [`tf.reverse`](https://www.tensorflow.org/versions/r2.13/api_docs/python/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]
