tf.Variable(initializer,name),参数initializer是初始化参数，name是可自定义的变量名称，用法如下： import tensorflow as tf v1...=tf.Variable(tf.random_normal(shape=[4,3],mean=0,stddev=1),name='v1') v2=tf.Variable(tf.constant(2),name...(tf.zeros([3, 3, 3]), name="v1") v2 = tf.Variable(tf.ones([10, 5]), name="v2") # 填充单值矩阵 v3 = tf.Variable...name="weights") biases = tf.Variable(tf.zeros([200]), name="biases") ... # Add an op to initialize the...当然也可以这样写：encoding:UTF-8 import tensorflow as tf这句话是导入tensorflow 模块 state = tf.Variable(0 , name='counter
