Bug:
We use two different Saver objects during training, one to initialize from a
checkpoint and another to save and restore from checkpoints during training.
Both these Savers were bound to same variable name causing init_fn function
to use the latter instead of the former when called.

For details see our paper:
"Speed/accuracy trade-offs for modern convolutional object detectors."
