Question

我正在尝试创建一个新组件，该组件几乎可以作为预配置的自动完成功能。 XBL组件文档非常简短，因此我尽可能地进行了调整，并获得了以下结果：

import numpy as np

class Layer:
    def __init__(self, weights_matrix, bias_vector, sigmoid_activation = True):
        self.weights_matrix = weights_matrix
        self.bias_vector = bias_vector
        self.sigmoid_activation = sigmoid_activation

    def compute_value(self, x_vector):
        result = np.add(np.dot(self.weights_matrix, x_vector), self.bias_vector)
        if self.sigmoid_activation:
            result = np.exp(-result)
            result = 1 / (1 + result)

        return result

    def compute_value_and_derivative(self, x_vector):
        if not self.sigmoid_activation:
            return (self.compute_value(x_vector), self.weights_matrix)
        temp = np.add(np.dot(self.weights_matrix, x_vector), self.bias_vector)
        temp = np.exp(-temp)
        value = 1.0 / (1 + temp)
        temp = temp / (1 + temp)**2
        #pre-multiplying by a diagonal matrix multiplies each row by
        #the corresponding diagonal element
        #(1st row with 1st value, 2nd row with 2nd value, etc...)
        jacobian = np.dot(np.diag(temp), self.weights_matrix)
        return (value, jacobian)

class Network:
    def __init__(self, layers):
        self.layers = layers

    def compute_value(self, x_vector):
        for l in self.layers:
            x_vector = l.compute_value(x_vector)

        return x_vector

    def compute_value_and_derivative(self, x_vector):
        x_vector, jacobian = self.layers[0].compute_value_and_derivative(x_vector)
        for l in self.layers[1:]:
            x_vector, j = l.compute_value_and_derivative(x_vector)
            jacobian = np.dot(j, jacobian)

        return x_vector, jacobian

#first weights
l1w = np.array([[1,1],[1,1]])
l1b = np.array([1,1])

l2w = np.array([[1,1],[1,1]])
l2b = np.array([1,1])

l3w = np.array([1, 1])
l3b = np.array([0])

nn = Network([Layer(l1w, l1b),
              Layer(l2w, l2b),
              Layer(l3w, l3b, False)])

r = nn.compute_value_and_derivative(np.array([1,1]))
print r

有2个问题：

选择器不再起作用-它没有根据值更改查询服务
警报和帮助文本有效，但是它们未显示在相应选项卡的构建器的“控制设置”对话框中

知道我在做什么错吗？

使用自动完成功能的新组件
