类型错误：+= 不支持的操作数类型：“QuantumCircuit”和“QuantumCircuit”

Question

我尝试使用 qiskit 的 Quantum CNN 来训练我的模型，但在此代码行中出现错误

backend = qiskit.Aer.get_backend('qasm_simulator')
filter_size = 2
circ = QuanvCircuit(filter_size, backend, 100, 127)
data = torch.tensor([[0, 200], [100, 255]])

print(data.size())
print(circ.run(data))

circ._circuit.draw(output='mpl')

错误是

TypeError                                 Traceback (most recent call last)

<ipython-input-18-c2f77b5d5f07> in <cell line: 3>()
      1 backend = qiskit.Aer.get_backend('qasm_simulator')
      2 filter_size = 2
----> 3 circ = QuanvCircuit(filter_size, backend, 100, 127)
      4 data = torch.tensor([[0, 200], [100, 255]])
      5

TypeError: unsupported operand type(s) for +=: 'QuantumCircuit' and 'QuantumCircuit'

任何人都知道如何解决它

量子卷积（qiskit）
