tf.identity is useful when you want to explicitly transport tensor between devices (like, from GPU to a CPU). The op adds send/recv nodes to the graph, which make a copy when the devices of the input and the output are different. A default behavior i…
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…
