该章介绍有关变量的API

变量

class tf.Variable

解释：这个函数的作用是初始化一个变量，这里有一个对于变量操作的一个高度概括。

一个变量

tf.SparseTensor.__init__(indices, values, shape)

解释：这个函数的作用是构建一个SparseTensor。

输入参数：

TensorFlow的系统结构以C API为界，将整个系统分为「前端」和「后端」两个子系统： ·        前端系统：主要扮演Client的角色，主要负责计算图的构造，并管理Session生命周期过程。是一个支持多语言的编程环境，并提供统一的编程模型支撑用户构造计算图。Client通过Session，连接TensorFlow后端的「运行时」，启动计算图的执行过程。 ·        后端系
