Enum Values

dnnl_sparse_encoding_undef

Undefined sparse encoding kind, used for empty memory descriptors.

dnnl_csr

Compressed Sparse Row (CSR) encoding.

dnnl_packed

An encoding that is used for an opaque storage schema for tensors with unstructured sparsity.

A memory descriptor with the packed encoding cannot be used to create a memory object. It can only be used to create a primitive descriptor to query the actual memory descriptor (similar to the format tag any).

dnnl_coo

Coordinate Sparse Encoding (COO).
