我正在尝试使用 Neupy python 库使用 Levenberg-Marquardt 优化器算法构建一个简单的前馈网络，但它不会编译，因为它似乎缺少 scan_perform 模块。如果我将优化器算法更改为 GradientDescent，那么它可以正常工作。
重现错误所需的代码是：
from neupy import algorithms
from neupy.layers import *
net = Input(2) >> Sigmoid(2) >> Linear(1)
opt = algorithms.LevenbergMarquardt(net)
我得到的错误是：

正如我上面所说，如果我将底线更改为opt = algorithms.GradientDescent(net)，它可以正常工作，它只是 LevenbergMarquardt 和 Hessian 以及其他基于牛顿方法的方法。
知道如何解决这个问题吗？
