Fields

offset_dims: Vec<i64>

"Window indices" is a term for a set of indices that index into the interior of a dynamic-slice from the input tensor, the starting indices for which were computed from output_gather_dims (see the operation semantic for how this is defined) and the start_indices tensor.

The window indices for a specific output index Out is computed as:

i = 0 for (k : [0, input_tensor_shape.rank)) window_indices[k] = if k in collapsed_slice_dims then 0 else Out[offset_dims[i++]]

collapsed_slice_dims: Vec<i64>

start_index_map: Vec<i64>

This is interpreted as a map from i to start_index_map[i]. It transforms the gather index looked up from the start_indices tensor into the starting index in the input space.

index_vector_dim: i64

The dimension in the start_indices input that contains the starting indices.
