intptr_t handle,
intptr_t desc_tensor_in,
intptr_t desc_tensor_u,
intptr_t desc_tensor_v,
intptr_t svd_config,

)[source]#

Computes the workspace size needed to perform the tensor SVD operation.

Parameters:

  • handle (intptr_t) – Opaque handle holding cuTensorNet’s library context.

  • desc_tensor_in (intptr_t) – Describes the modes, extents and other metadata information for a tensor.

  • desc_tensor_u (intptr_t) – Describes the modes, extents and other metadata information for the output tensor U.

  • desc_tensor_v (intptr_t) – Describes the modes, extents and other metadata information for the output tensor V.

  • svd_config (intptr_t) – This data structure holds the user-requested svd parameters.

  • work_desc (intptr_t) – The workspace descriptor in which the information is collected.
