Why is the result of NDCG not stored in the eval_result.txt file?

[linh47]

After running run_beauty.sh,I got eval_result.txt.
The eval_result.txt only included masked_lm_accuracy and masked_lm_loss.
I tried and found that NDCG and other evaluation metrics only outputed in the info log.
Could you please tell me how can I get these evaluation metrics results and store them in the result txt file?
I found the source codes as followed:
` #tf.logging.info('special eval ops:', special_eval_ops)
result = estimator.evaluate(
input_fn=eval_input_fn,
steps=None,
hooks=[EvalHooks()])

    output_eval_file = os.path.join(FLAGS.checkpointDir,
                                    "eval_results.txt")
    with tf.gfile.GFile(output_eval_file, "w") as writer:
        tf.logging.info("***** Eval results *****")
        tf.logging.info(bert_config.to_json_string())
        writer.write(bert_config.to_json_string()+'\n')
        for key in sorted(result.keys()):
            tf.logging.info("  %s = %s", key, str(result[key]))
            writer.write("%s = %s\n" % (key, str(result[key])))`
