class Age_Model(): def __init__(self): self.model = self.loadModel() self.output_indexes = np.array([i for i in range(0, 101)]) def predict_age(self,face_image): image_preprocesing = self.transform_face_array2age_face(face_image) age_predictions = self.model.predict(image_preprocesing )[0,:] result_age = self.findApparentAge(age_predictions) return result_age def loadModel(self): model = VGGFace.baseModel() #-------------------------- classes = 101#101 base_model_output = Sequential() base_model_output = Convolution2D(classes, (1, 1), name='predictions')(model.layers[-4].output) base_model_output = Flatten()(base_model_output) base_model_output = Activation('softmax')(base_model_output) #-------------------------- age_model = Model(inputs=model.input, outputs=base_model_output) #-------------------------- home = str(Path.home()) age_model.load_weights(home+'/.deepface/weights/age_model_weights.h5') return age_model

这段代码是一个基于VGGFace模型的年龄预测模型。其中，loadModel函数用于加载预训练的模型权重；predict_age函数用于对输入的人脸图像进行预测，返回预测结果的年龄。

具体来说，该模型使用VGGFace模型作为基础模型。在VGGFace模型上，我们添加了一个具有101个输出类别的全连接层，用于预测101个年龄区间。具体的输出层添加代码为：

base_model_output = Convolution2D(classes, (1, 1), name='predictions')(model.layers[-4].output)
base_model_output = Flatten()(base_model_output)
base_model_output = Activation('softmax')(base_model_output)

在预测时，输入的人脸图像经过预处理之后，通过该模型进行预测，得到101个年龄区间的预测概率。最终，根据预测概率的分布，计算出预测的年龄值。

Please use new-style autograd function with static forward method. 如何修改代码

这个错误提示是因为代码中使用了旧版本的autograd函数，需要使用新版本的autograd函数。可以使用`@staticmethod`修饰`GuidedBackpropReLU`类中的`forward`方法，将其转换为静态方法。修改后的代码如下：

class GuidedBackpropReLU(nn.ReLU):
    @staticmethod
    def forward(input):
        output = torch.clamp(input, min=0.0)
        grad = torch.zeros_like(output)
        grad[output > 0] = 1.0
        output = output * grad
        return output

class GuidedBackpropReLUModel:
    def __init__(self, model, use_cuda):
        self.model = model
        self.model.eval()
        self.cuda = use_cuda
        if self.cuda:
            self.model = model.cuda() 
        for idx, module in self.model.features._modules.items():
            if module.__class__.__name__ == 'ReLU':
                self.model.features._modules[idx] = GuidedBackpropReLU()

    def forward(self, input):
        return self.model(input)

    def forward_static(self, input):
        if self.cuda:
            output = self.forward(input.cuda())
        else:
            output = self.forward(input)
        return output

    def __call__(self, input, index=None):
        output = self.forward_static(input)
        if index is None:
            index = np.argmax(output.cpu().data.numpy())
        one_hot = np.zeros((1, output.size()[-1]), dtype=np.float32)
        one_hot[0][index] = 1
        one_hot = Variable(torch.from_numpy(one_hot), requires_grad=True)
        if self.cuda:
            one_hot = torch.sum(one_hot.cuda() * output)
        else:
            one_hot = torch.sum(one_hot * output)
        one_hot.backward()

        output = input.grad.cpu().data.numpy()
        output = output[0, :, :, :]
        return output

抱歉，由于排版原因，我之前的代码示例可能没有显示完整。以下是完整的代码示例：

    def __init__(self, name, age=0):
        self._name = name

    @property
    def name(self):
        return self._name
    
    @name.setter
    def name(self, value):
        self._name = value
    
    @property
    def age(self):
        return self._age
    
    @age.setter
    def age(self, value):
        self._age = value
