__len__()

int pyqpanda3.vqcircuit.vqcircuit.ResNGradients.__len__

(

self

)

len(self: vqcircuit.ResNGradients) -> int

return the total of gradient groups, which equal N

at() [1/2]

Any pyqpanda3.vqcircuit.vqcircuit.ResNGradients.at	(		self,
			idx )

at(self: vqcircuit.ResNGradients, idx: int) -> vqcircuit.ResGradients

Pass in N sets of parameters to generate N quantum circuits and their corresponding N sets of gradient values. The at(idx) method is used to retrieve all gradient values corresponding to the idx-th set of parameters, with the result returned as a ResGradients object.

at() [2/2]

ResGradients pyqpanda3.vqcircuit.vqcircuit.ResNGradients.at	(		self,
		int	idx )

at(self: vqcircuit.ResNGradients, idx: int) -> vqcircuit.ResGradients

Pass in N sets of parameters to generate N quantum circuits and their corresponding N sets of gradient values. The at(idx) method is used to retrieve all gradient values corresponding to the idx-th set of parameters, with the result returned as a ResGradients object.

data()

list[list[float]] pyqpanda3.vqcircuit.vqcircuit.ResNGradients.data

(

self

)

data(self: vqcircuit.ResNGradients) -> list[list[float]]

The internal data storing gradient values is returned as a combination of built-in types. It returns a list where each element is a list that stores a set of gradients. This set of gradients corresponds to a specific set of parameters.
