如何用Tensorflow 快速搭建神经网络|莫烦

import tensorflow as tf def add_layer(inputs,in_size,out_size,activation_function=None): Weights = tf.Variable(tf.random_normal([in_size,out_size])) biases = tf.Variable(tf.zeros([1,out_size])+0.1) Wx_plus_b = tf.matmul(inputs,Weights)+biases if activation_function is None: outputs = Wx_plus_b else: outputs = activation_function ( Wx_plus_b) return outputs
