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.
