菜尼奥排错之keras TypeError: _init_subclassed_network() got an unexpected keyword argument ‘input‘_typeerror: forward() got an unexpected keyword arg

环境版本：

Ubuntu 18.04.2 LTS

Nvidia GeForce RTX2080super CUDA Version 10.0

tensorflow-gpu 1.13.1

keras 2.2.4-tf

报错信息：

诸如此类：

TypeError: _init_subclassed_network() got an unexpected keyword argument 'input'
 
TypeError: forward() got an unexpected keyword argument 'input'
 
TypeError: Decoder() got an unexpected keyword argument 'input'
 
TypeError: xxxxxx() got an unexpected keyword argument 'input'

本人是在运行Unet时出现的此问题：

Traceback (most recent call last):
  File "unet.py", line 185, in <module>
    myunet.train()
  File "unet.py", line 164, in train
    model = self.get_unet()
  File "unet.py", line 154, in get_unet
    model = Model(input = inputs, output = conv10)
  File "/home/xxx/anaconda3/lib/python3.6/site-packages/tensorflow/python/keras/engine/training.py", line 121, in __init__
    super(Model, self).__init__(*args, **kwargs)
  File "/home/xxx/anaconda3/lib/python3.6/site-packages/tensorflow/python/keras/engine/network.py", line 84, in __init__
    self._init_subclassed_network(**kwargs)
  File "/home/xxx/anaconda3/lib/python3.6/site-packages/tensorflow/python/training/checkpointable/base.py", line 442, in _method_wrapper
    method(self, *args, **kwargs)
TypeError: _init_subclassed_network() got an unexpected keyword argument 'input'

原因分析：

查看自己环境中keras对应版本的函数调用方法，得知是版本不同造成的。

#旧版本中代码：
from keras.models import Model
model = Model(input = inputs, output = conv10)
 
#新版本中代码：
from tensorflow.python.keras.models import Model
model = Model(inputs = inputs, outputs = conv10)
 
#出现UserWarning不用理会

同理， Decoder(inputs=out_sents_, encoder_hidden=en_hidden, encoder_outputs=en_output)函数报错也是一样的原因。

results = Decoder(inputs=out_sents_, encoder_hidden=en_hidden, encoder_outputs=en_output)
#修改如下
results = Decoder(out_sents_, en_hidden)

解决方案：

方案一："input"修改为"inputs"，"output"修改为"outputs"。

model = Model(input = inputs, output = conv10)
#修改如下，参数根据自己的需要调整
model = Model(inputs = inputs, outputs = conv10)

方案二：删除"input"/"output"参数名即可。

model = Model(input = inputs, output = conv10)
#修改如下，参数根据自己的需要调整
model = Model(inputs, conv10)
