batch_size = 32 为什么运行后每一个 Epoch 下不是显示 32 个批次，而只是显示一个批次？

老师，下午好！
RT,

history = model.fit(x_train, y_train, epochs = 10, batch_size = 32,
                    validation_data = (x_valid, y_valid))

输出结果是：

Epoch 1/10
1719/1719 [==============================] - 3s 2ms/step - loss: 13.4092 - accuracy: 0.6626 - val_loss: 0.5988 - val_accuracy: 0.7938
Epoch 2/10

为什么会是上面这样，
根据 https://mp.weixin.qq.com/s/FFF6RSudAas7j2vHqP5j2Q
输出结果应该是：

Epoch 1/10
1719/1719 [==============================] - 3s 2ms/step - loss: 13.4092 - accuracy: 0.6626 - val_loss: 0.5988 - val_accuracy: 0.7938
1719/1719 [==============================] - 3s 2ms/step - loss: 13.4092 - accuracy: 0.6626 - val_loss: 0.5988 - val_accuracy: 0.7938
1719/1719 [==============================] - 3s 2ms/step - loss: 13.4092 - accuracy: 0.6626 - val_loss: 0.5988 - val_accuracy: 0.7938
...
这样一共有32次才到
Epoch 2/10 
呀？

谢谢老师解答！！！
