尽管步骤很少，但Tensorboard TF事件文件太大

Question

我在下面粘贴了部分代码（所有指向张量板部分的部分）。我只记录损失标量变量，并且仅在一个时期添加一次摘要。我总共跑了3个纪元。理想情况下，该文件应该是非常小的tfevents文件。但是，tfevents文件为1.3GB。我不确定是什么导致文件太大。 愿意在需要时分享其余代码

def do_training(update_op, loss, summary_op):

    writer = tf.summary.FileWriter(logs_path, graph=tf.get_default_graph())
    saver = tf.train.Saver()
    with tf.Session() as sess:
        sess.run(tf.global_variables_initializer())
        try:
            step = 0
            while True:

                if step % (X_train.shape[0]/batch_size) == 0:
                    _, loss_value = sess.run((update_op, loss))
                    summary = sess.run(summary_op)
                    writer.add_summary(summary, global_step=step)
                    print('Step {} with loss {}'.format(step, loss_value))
                else:
                    _, loss_value = sess.run((update_op, loss))
                step += 1

        except tf.errors.OutOfRangeError:
            # we're through the dataset
            pass
        writer.close()
