cuquantum.cutensornet.contraction_optimizer_info_get_attribute¶

cuquantum.cutensornet.contraction_optimizer_info_get_attribute(intptr_t handle, intptr_t optimizer_info, int attr, intptr_t buf, size_t size_in_bytes)[source]¶

Gets attributes of optimizer_info.

Parameters

handle (intptr_t) – Opaque handle holding cuTensorNet’s library context.
optimizer_info (intptr_t) – Opaque structure that is accessed.
attr (ContractionOptimizerInfoAttribute) – Specifies the attribute that is requested.
buf (intptr_t) – On return, this buffer (of size size_in_bytes) holds the value that corresponds to attr within optimizeInfo.
size_in_bytes (size_t) – Size of buf (in bytes).

Note

To compute the attribute size, use the itemsize of the corresponding data type, which can be queried using get_contraction_optimizer_info_attribute_dtype().
