Enum Values

undef

Undefined sparse encoding kind, used for empty memory descriptors.

csr

Compressed Sparse Row (CSR) encoding.

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).

coo

Coordinate Sparse (COO) encoding.
