cuquantum.cutensornet.expectation_configure¶

cuquantum.cutensornet.expectation_configure(intptr_t handle, intptr_t expectation, int attr, intptr_t buf, size_t size)[source]¶

Configures computation of the tensor network state expectation value.

Parameters

handle (intptr_t) – The library handle.
expectation (intptr_t) – The tensor network expectation computation handle.
attr (ExpectationAttribute) – The attribute to configure.
buf (intptr_t) – The pointer address (as Python int) of the attribute value.
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 expectation_get_attribute_dtype().
