plan_preference_get_attribute#

nvmath.bindings.cutensor.plan_preference_get_attribute( intptr_t handle, intptr_t pref, int attr, intptr_t buf, size_t size_in_bytes, )[source]#

Get attribute of a cutensorPlanPreference_t object.

Parameters:

handle (intptr_t) – Opaque handle holding cuTENSOR’s library context.
pref (intptr_t) – This opaque struct restricts the search space of viable candidates.
attr (PlanPreferenceAttribute) – Requested attribute.
buf (intptr_t) – On successful exit: Holds the information of the requested attribute.
size_in_bytes (size_t) – Size of buf (in bytes); see cutensorPlanPreferenceAttribute_t for the exact size.

Note

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