tf.train.Supervisor可以简化编程,避免显示地实现restore操作.通过一个例子看. import tensorflow as tf import numpy as np import os log_path = r"D:\Source\model\linear" log_name = "linear.ckpt" # Create 100 phony x, y data points in NumPy, y = x * 0.1 + 0.3 x_da…
tf.set_random_seed(seed) 可使得所有会话中op产生的随机序列是相等可重复的. 例如: tf.set_random_seed(1234) a = tf.random_uniform([1]) b = tf.random_normal([1]) # Repeatedly running this block with the same graph will generate different # sequences of 'a' and 'b'. print("Sessio…
TensorFlow [1] is an interface for expressing machine learning algorithms, and an implementation for executing such algorithms. TensorFlow的功能:1.提供接口表达机器学习算法.2.执行这些机器学习算法. A computation expressed using TensorFlow can be executed with little or no chan…
