函数原型: tf.assign(ref, value, validate_shape=None, use_locking=None, name=None) Defined in tensorflow/python/ops/state_ops.py. 将 value 赋值给 ref,并输出 ref,即 ref = value: 这使得需要使用复位值的连续操作变简单 Defined in tensorflow/python/framework/tensor_shape.py. Arg…
tf.expand_dims和tf.squeeze函数 一.tf.expand_dims() Function tf.expand_dims(input, axis=None, name=None, dim=None) Inserts a dimension of 1 into a tensor’s shape. 在第axis位置增加一个维度 Given a tensor input, this operation inserts a dimension of 1 at the dimensio…
tf.name_scope() 此函数作用是共享变量.在一个作用域scope内共享一些变量,简单来说,就是给变量名前面加个变量空间名,只限于tf.Variable()的变量 tf.variable_scope() 和tf.name_scope()作用一样,不过包括tf.get_variable()的变量和tf.Variable()的变量 在同一个程序中多次调用,在第一次调用之后需要将reuse参数设置为True with tf.variable_scope("one"): a = tf…
