报错：
tensorflow.python.framework.errors_impl.DataLossError: Unable to open table file /home/wpq/data/model.ckpt.data-00000-of-00001: Data loss: not an sstable (bad magic number): perhaps your file is in a different file format and you need to use a different restore operator?
解决方案：
I have fixed the issue by this: replace model.ckpt the model.ckpt.data-00000-of-00001 即使用 model.ckpt替换 model.ckpt.data-00000-of-00001，去掉model.ckpt.data-00000-of-00001的后缀即可
