tf.raw_ops.Gather
Gather slices from params according to indices.
tf.raw_ops.Gather(
params, indices, validate_indices=True, name=None
)
indices must be an integer tensor of any dimension (usually 0-D or 1-D). Produces an output tensor with shape indices.shape + params.shape[1:] where:
# Scalar indices
output[:, ..., :] = params[indices, :, ... :]
# Vector indices
output[i, :, ..., :] = params[indices[i], :, ... :]
# Higher rank indices
output[i, ..., j, :, ... :] = params[indices[i, ..., j], :, ..., :]
If indices is a permutation and len(indices) == params.shape[0] then this operation will permute params accordingly.
validate_indices: DEPRECATED. If this operation is assigned to CPU, values in indices are always validated to be within range. If assigned to GPU, out-of-bound indices result in safe but unspecified behavior, which may include raising an error.
| Args | |
|---|---|
params |
A Tensor. |
indices |
A Tensor. Must be one of the following types: int32, int64. |
validate_indices |
An optional bool. Defaults to True. |
name |
A name for the operation (optional). |
| Returns | |
|---|---|
A Tensor. Has the same type as params. |
