TorchConnector

class TorchConnector(*args, **kwargs)

Базовые классы: torch.nn.Module

Connects a Qiskit (Quantum) Neural Network to PyTorch.

Параметры:

• neural_network (NeuralNetwork) – The neural network to be connected to PyTorch. Remember that input_gradients must be set to True in the neural network initialization before passing it to the TorchConnector for the gradient computations to work properly during training.

• initial_weights (np.ndarray | Tensor | None) – The initial weights to start training the network. If this is None, the initial weights are chosen uniformly at random from [-1, 1].

• sparse (bool | None) – Whether this connector should return sparse output or not. If sparse is set to None, then the setting from the given neural network is used. Note that sparse output is only returned if the underlying neural network also returns sparse output, otherwise an error will be raised.

Исключение:

QiskitMachineLearningError – If the connector is configured as sparse and the underlying network is not sparse.
