tf.ragged.row_splits_to_segment_ids
Generates the segmentation corresponding to a RaggedTensor row_splits.
tf.ragged.row_splits_to_segment_ids(
splits, name=None, out_type=None
)
Returns an integer vector segment_ids, where segment_ids[i] == j if splits[j] <= i < splits[j+1]. Example:
print(tf.ragged.row_splits_to_segment_ids([0, 3, 3, 5, 6, 9]))
tf.Tensor([0 0 0 2 2 3 4 4 4], shape=(9,), dtype=int64)
| Args |
|---|
splits | A sorted 1-D integer Tensor. splits[0] must be zero. |
name | A name prefix for the returned tensor (optional). |
out_type | The dtype for the return value. Defaults to splits.dtype, or tf.int64 if splits does not have a dtype. |
| Returns |
|---|
A sorted 1-D integer Tensor, with shape=[splits[-1]] |
| Raises |
|---|
ValueError | If splits is invalid. |
