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

This function retrieves an attribute of the provided cutensorOperationDescriptor_t object (see cutensorOperationDescriptorAttribute_t).

Parameters:

  • handle (intptr_t) – Opaque handle holding cuTENSOR’s library context.

  • desc (intptr_t) – The cutensorOperationDescriptor_t object whos attribute is queried.

  • attr (OperationDescriptorAttribute) – Specifies the attribute that will be retrieved.

  • buf (intptr_t) – This buffer (of size size_in_bytes) will hold the requested attribute of the provided cutensorOperationDescriptor_t object.

  • size_in_bytes (size_t) – Size of buf (in bytes); see cutensorOperationDescriptorAttribute_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_operation_descriptor_attribute_dtype().
