【问题描述】:
我在 GPU 集群上训练了 TensorFlow 模型,并使用
保存了模型saver = tf.train.Saver()
saver.save(sess, config.model_file, global_step=global_step)
现在我正在尝试使用
恢复模型saver = tf.train.import_meta_graph('model-1000.meta')
saver.restore(sess,tf.train.latest_checkpoint(save_path))
用于评估,在不同的系统上。问题是saver.restore
产生以下错误:

似乎有一些路径存储在模型或 checkpoint 文件中,形成了训练它的系统,在我正在评估的系统上不再有效。复制 model-X.meta、model-X.index 和 checkpoint 文件后,如何在不同的机器上恢复模型(用于评估)?
【问题讨论】:
-
使用绝对路径到元文件并保存路径,/home/jon/saved/model-1000.meta' 和 save_path=/home/jon/saved
-
@Eliethesaiyan 我是。
-
可能与您恢复的模型无关,您能否发布完整的错误日志,错误指向完全相同的行吗?
