tf.train.CheckpointOptions( experimental_io_device=None )
Used as the
_options argument to the
tf.Checkpoint constructor to adjust
how variables are saved.
Example: Run IO ops on "localhost" while saving a checkpoint:
step = tf.Variable(0, name="step") checkpoint = tf.Checkpoint(step=step) options = tf.CheckpointOptions(experimental_io_device="/job:localhost") checkpoint.save("/tmp/ckpt", options=options)
string. Applies in a distributed setting.
Tensorflow device to use to access the filesystem. If
This is for example useful if you want to save to a local directory, such as "/tmp" when running in a distributed setting. In that case pass a device for the host where the "/tmp" directory is accessible.
