# gatherAlongAxis(indices:axis:) Adds a gather-along-axis operation to the current graph. ``` func gatherAlongAxis(indices: some BNNSGraph.Builder.OperationParameter, axis: Int) -> BNNSGraph.Builder.Tensor ``` ## Parameters `indices` The indices that the operation gathers. `axis` The axis over which the operation gathers. ## Discussion Register a gather along axis op, which shuffles the input along one axis. In particular, output `y` such that `y[L…, i, T…] = x[L…, indices[L…, i, T…], T…]. --- Copyright © 2026 Apple Inc.
