cuquantum.cutensornet.workspace_compute_svd_sizes¶

cuquantum.cutensornet.workspace_compute_svd_sizes(intptr_t handle, intptr_t desc_tensor_in, intptr_t desc_tensor_u, intptr_t desc_tensor_v, intptr_t svd_config, intptr_t work_desc)[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.
