Qiskit QAOA编译错误，Evolvedop对象没有属性＆＃x27; broadcast_arguments

Question

如今，我正在研究量子计算。 当我确实遵循此代码时，我会遇到错误。 我不知道为什么会有这个错误。

我刚刚搜索解决这个问题。 在下面，miniMumeGenopTimizer.solve（）输入是四边形的。 miniMumeMumeGenopTimizer.Solve（问题）

函数的参数miniMumeMumeigenOptimizer.solve（），是四边形的。

在以下代码中，我遵循参数的规则。

# generate qiskit's cost function
qiskit_cost_function = QuadraticProgram()

错误是：

你能给我一只手吗？请帮我！ 我非常非常初学者。
