Tensorflow saver无法正常工作

Question

我做了一个保存程序来保存我的模型在我的测试模块。因为tensorflow使用了一个新的保存方案，所以它不直接存储.ckpt文件。所以我们用.data-00000-of-00001和.index文件代替.ckpt文件。在

我的保存代码：

saver = tf.train.Saver()
save_path = saver.save(sess, 'D:\Speech_Project\my_model\my_model_01')

以及恢复：

^{pr2}$

我得到的错误是：

TypeError: expected bytes, NoneType found

During handling of the above exception, another exception occurred:

请注意，所有代码都在同一个.py文件中。Tensorflow 1.0.1版，适用于Windows CPU版本。即使

graph = tf.get_default_graph()

错误是一样的。需要你的见解。在
