TF segfault

W0401 13:47:33.782922 140134609663744 basic_session_run_hooks.py:732] It seems that global step (tf.train.get_global_step) 
has not been increased. Current value (could be stable): 0 vs previous value: 0. You could increase the global step by pass
ing tf.train.get_global_step() to Optimizer.apply_gradients or Optimizer.minimize.
