def list_variables(ckpt_dir_or_file):
"""Returns list of all variables in the checkpoint.
"""Lists the checkpoint keys and shapes of variables in a checkpoint.
Checkpoint keys are paths in a checkpoint graph.
Example usage:
```python
import tensorflow as tf
import os
ckpt_directory = "/tmp/training_checkpoints/ckpt"
ckpt = tf.train.Checkpoint(optimizer=optimizer, model=model)
manager = tf.train.CheckpointManager(ckpt, ckpt_directory, max_to_keep=3)
train_and_checkpoint(model, manager)
tf.train.list_variables(manager.latest_checkpoint)
```
Args:
ckpt_dir_or_file: Directory with checkpoints file or path to checkpoint.
Returns:
List of tuples `(name, shape)`.
List of tuples `(key, shape)`.
