如何將合併函數轉換爲Keras 2中可讀的？

Question

我有一個程序，它已被寫入Keras 1.x.x，我試圖在Keras 2.x.x中重新運行它。然而，當它達到這一點，

from keras.layers import Input, merge 

up2 = merge([UpSampling2D(size=(2, 2))(conv5), conv4], mode='concat', concat_axis=1) 

它顯示了以下錯誤：

UserWarning: The `merge` function is deprecated and will be removed after 08/2017. Use instead layers from `keras.layers.merge`, e.g. `add`, `concatenate`, etc. 
    up1 = merge([UpSampling2D(size=(2, 2))(conv3), conv2], mode='concat', concat_axis=1) 
/usr/local/python/3.5.2-gcc4/externalmodules/lib/python3.5/site-packages/keras/legacy/layers.py:456: UserWarning: The `Merge` layer is deprecated and will be removed after 08/2017. Use instead layers from `keras.layers.merge`, e.g. `add`, `concatenate`, etc. 
    name=name) 

我並沒有改變任何東西，甚至數據是一樣的。你能指導我如何轉換合併函數在Keras 2.x.x.上可讀？謝謝

警告已清除。您應該使用kears.layers.merge.Concatenate而不是merge。

from keras.layers.merge import Concatenate 
up2 = Concatenate([UpSampling2D(size=(2, 2))(conv5), conv4], axis=1)
