cuquantum.cutensornet.expectation_configure(intptr_t handle, intptr_t tensor_network_expectation, int attribute, intptr_t attribute_value, size_t attribute_size)[source]

Configures computation of the requested tensor network state expectation value.

  • handle (intptr_t) – cuTensorNet library handle.

  • tensor_network_expectation (intptr_t) – Tensor network state expectation value representation.

  • attribute (ExpectationAttribute) – Configuration attribute.

  • attribute_value (intptr_t) – Pointer to the configuration attribute value (type-erased).

  • attribute_size (size_t) – The size of the configuration attribute value.


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