cuquantum.cutensornet.sampler_get_info¶

cuquantum.cutensornet.sampler_get_info(intptr_t handle, intptr_t tensor_network_sampler, int attribute, intptr_t attribute_value, size_t attribute_size)[source]¶

Retrieves an attribute related to tensor network state sampling.

Parameters

handle (intptr_t) – cuTensorNet library handle.
tensor_network_sampler (intptr_t) – Tensor network state sampler.
attribute (SamplerAttribute) – Information attribute.
attribute_value (intptr_t) – Pointer to the information attribute value (type-erased).
attribute_size (size_t) – The size of the information attribute value.

Note

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