tf.math.cumprod

Compute the cumulative product of the tensor x along axis.

By default, this op performs an inclusive cumprod, which means that the first element of the input is identical to the first element of the output:

tf.math.cumprod([a, b, c])  # [a, a * b, a * b * c]

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

tf.math.cumprod([a, b, c], exclusive=True)  # [1, a, a * b]

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

tf.math.cumprod([a, b, c], reverse=True)  # [a * b * c, b * c, c]

This is more efficient than using separate tf.reverse ops. The reverse and exclusive kwargs can also be combined:

tf.math.cumprod([a, b, c], exclusive=True, reverse=True)  # [b * c, c, 1]

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)).
exclusive If True, perform exclusive cumprod.
reverse A bool (default: False).
name A name for the operation (optional).

A Tensor. Has the same type as x.
