cuquantum.cutensornet.workspace_compute_qr_sizes¶

cuquantum.cutensornet.workspace_compute_qr_sizes(intptr_t handle, intptr_t desc_tensor_in, intptr_t desc_tensor_q, intptr_t desc_tensor_r, intptr_t work_desc)[source]¶

Computes the workspace size needed to perform the tensor QR 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_q (intptr_t) – Describes the modes, extents and other metadata information for the output tensor Q.
desc_tensor_r (intptr_t) – Describes the modes, extents and other metadata information for the output tensor R.
work_desc (intptr_t) – The workspace descriptor in which the information is collected.
