plan_get_attribute#

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

Retrieves information about an already-created plan (see cutensorPlanAttribute_t).

Parameters:

handle (intptr_t) – Denotes an already-created plan (e.g., via cutensorCreatePlan or cutensorCreatePlanAutotuned).
plan (intptr_t) – Requested attribute.
attr (PlanAttribute) – On successful exit: Holds the information of the requested attribute.
buf (intptr_t) – size of buf in bytes.
size_in_bytes (size_t) – The operation completed successfully.

Note

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