orqa ict training it seems stop at evaluation

hi guys ,i was running on centos and tf2.1 4 v100 GPUS

python -m language.orqa.experiments.ict_experiment --model_dir=/home/wjd/workspace/Reference_Repority/language_model_master/language/orqa/ict_model --bert_hub_module_path=/home/wjd/workspace/Reference_Repority/language_model_master/language/orqa/bert_tf_hub/bert_uncased_L-12_H-768_A-12_1 --examples_path=/home/wjd/workspace/Reference_Repority/language_model_master/wikipedia_base/examples.tfr --batch_size=32 --num_train_steps=100000 --use_tpu=False --save_checkpoints_steps=100

the following logs
