train.latest_checkpoint('./model_ckpt/')) # 加载模型中的变量 # sess.run(tf.global_variables_initializer()) # 重新初始化一下参数 print(sess.run(pred, feed_dict={X:feed_X})) 所以手动构建网络结构后,只需要saver.restore一下,就可以加载模型中的参数。另外,通过checkpoint这种模式加载进来的变量,依...

export_savedmodel("./saved_model/", serving_input_receiver_fn) 其实main中主要做三件事:1. 通过tf.estimator.RunConfig()配置构建Estimator对象;2. 初始化estimator(model_dir如果非空则自动热启动);3. 执行train/eval/infer/export任务。 train任务中初始化好TrainSpec和EvalSpec之后可以直接调用tf.estimator....
在TensorFlow中使用tf.train.Saver将训练好的模型进行保存。 saver = tf.train.Saver() 在循环训练过程中,saver.save()方法会定期执行,用于将模型当前状态写入到检查点文件中。 checkpoint_file =os.path.join(FLAGS.log_dir ,'model.ckpt') saver.save(sess, checkpoint_file, global_step =step) ...
