TensorFlow 中的 Saver 有跨平台的文件格式吗?

Does the Saver in TensorFlow have a cross-platform file format?

假设我在对一些 tf.Session sess 和一些 tf.train.Saver saver 进行一些计算后在机器 A 上执行以下命令,假设我有一些 tf.Graph G 带有一些变量 V:

with tf.Graph().as_default():
    # Define G, V, initialize for sess, then run some computation
    saver.save(sess, '/A/somefolder/somefile')

这将创建 somefilesomefile.meta,并在 somefolder 中更新 checkpoints

接下来,假设我在机器 B 上复制 somefolder 和 运行 的全部内容如下:

with tf.Graph().as_default():
    # Define G and V the same way. No initialization or run here.
    saver.restore(sess, '/B/somefolder/somefile')

对于机器A和B,变量在代码块末尾的状态是否相同?这是否保证适用于所有平台? Linux 的不同版本呢?

保存器使用简单的文件格式based on LevelDB to store a key-value table that maps variable names (as strings) to SavedTensorSlice protocol buffers. The format is intended to work across all platforms, although it has mostly been tested on little-endian (i.e. x86-based) architectures. The same file should work across different versions of Linux, and between Linux and Mac OS X. If it doesn't, please raise an issue!
