编译代码中的 Jupyter Notebook 语法错误

Question

尝试运行以下代码时出错请帮助

我已尝试运行以下代码，但一直出现错误

import numpy
import nnfs

from nnfs.datasets import spiral_data

nnfs.init
class layer_Dense:
    def init_(self, n_inputs, n_neurons):
        self.weights = 0.01 + np.random.randn(n_inputs, n_neurons)
        self.biases = np.zeros(1, n_neurons)
    def forward(self, inputs):
        self.output = np.dot(inputs, self.weights) + self.biases

class Activation_Relu:
    def forward(self, inputs):
        self.output= np.maximum(0, inputs)
    
class Activation_Softmax:
    def forward(self, inputs):
        exp_values= np.exp(inputs - np.max(inputs, axis=1, keepdims=True)
        probabilities = exp_values / np.sum(exp_values, axis=1, keepdims=True)
        self.output = probabilities
  

X, y = spiral_data(classes=100, samples=3)
dense= layer_dense(2,3)
Activation1= Activation_Relu()
dense2= layer_dense(3,3)
Activation2= ()

dense.forward(X)
Activation1.forward(dense.output)
dense2.forward(Activation1.output)
print(activation2.output[:5])

您在下面代码的最后一行中缺少右括号：

class Activation_Softmax:
    def forward(self, inputs):
        exp_values= np.exp(inputs - np.max(inputs, axis=1, keepdims=True))
