)
Readthe section on segmentationfor an explanation of segments.
Computes a tensor such that \(output_i = \prod_j data_j\) where the product is over j such that segment_ids[j] == i.
If the product is empty for a given segment ID i, output[i] = 1.
For example:
c = tf.constant([[1,2,3,4], [4, 3, 2, 1], [5,6,7,8]])
tf.segment_prod(c, tf.constant([0, 0, 1]))
# ==> [[4, 6, 6, 4],
# [5, 6, 7, 8]]
| Args | |
|---|---|
| data | A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, uint16, complex128, half, uint32, uint64. |
| segment_ids | A Tensor. Must be one of the following types: int32, int64. A 1-D tensor whose size is equal to the size of data's first dimension. Values should be sorted and can be repeated. |
| name | A name for the operation (optional). |
| Returns |
|---|
| A Tensor. Has the same type as data. |
