Validation was triggered on
global_step % validation_steps == 0, while checkpointinguses
(global_step + 1) % checkpointing_steps == 0. This one-step offset means theeval loss logged near a checkpoint does not correspond to that checkpoint's weights.
As a side effect, validation no longer runs at step 0 (on the barely-trained model right
after the first step)
