Parameters

handle (intptr_t) – The library handle.
info (intptr_t) – The optimizer info handle.
attr (ContractionOptimizerInfoAttribute) – The attribute to set.
buf (intptr_t) – The pointer address (as Python int) to the attribute data.
size (size_t) – The size of buf (in bytes).

Note

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