UseBlockSparseIndices property

Pointer<NativeFunction<OrtStatusPtr Function(Pointer<OrtValue> ort_value, Pointer<Int64> indices_shape, Size indices_shape_len, Pointer<Int32> indices_data)>> UseBlockSparseIndices

The assigns BlockSparse format indices to the SparseTensor that was created by OrtApi::CreateSparseTensorWithValuesAsOrtValue above. It also sets OrtSparseFormat to ORT_SPARSE_BLOCK_SPARSE. This will not allocate any additional memory for data. The life span of indices_data buffer must eclipse the lifespan of this ::OrtValue.

\paramin,out ort_value OrtValue instance constructed with OrtApi::CreateSparseTensorWithValuesAsOrtValue \paramin indices_shape pointer to indices shape. Use {0} for fully sparse tensors \paramin indices_shape_len length of the indices shape \paramin,out indices_data pointer to user pre-allocated buffer or nullptr for fully sparse tensors.
