class_docstr: The :class:`Model` class represents a neural network.
  
  It should be subclassed when implementing a dynamic model,
  where 'forward' method must be overwritten.
  Otherwise, please specify 'inputs' tensor(s) and 'outputs' tensor(s)
  to create a static model. In that case, 'inputs' tensors should come
  from tl.layers.Input().
  
  Parameters
  -----------
  inputs : a Layer or list of Layer
      The input(s) to the model.
  outputs : a Layer or list of Layer
      The output(s) to the model.
  name : None or str
      The name of the model.
  
  Methods
  ---------
  __init__(self, inputs=None, outputs=None, name=None)
      Initializing the Model.
  inputs()
      Get input tensors to this network (only avaiable for static model).
  outputs()
      Get output tensors to this network (only avaiable for static model).
  __call__(inputs, is_train=None, **kwargs)
      Forward input tensors through this network.
  all_layers()
      Get all layer objects of this network in a list of layers.
  weights()
      Get the weights of this network in a list of tensors.
  train()
      Set this network in training mode. (affect layers e.g. Dropout, BatchNorm).
  eval()
      Set this network in evaluation mode.
  as_layer()
      Set this network as a ModelLayer so that it can be integrated into another Model.
  release_memory()
      Release the memory that was taken up by tensors which are maintained by this network.
  save_weights(self, filepath, format='hdf5')
      Save the weights of this network in a given format.
  load_weights(self, filepath, format=None, in_order=True, skip=False)
      Load weights into this network from a specified file.
  save(self, filepath, save_weights=True)
      Save the network with/without weights.
  load(filepath, save_weights=True)
      Load the network with/without weights.
  
  Examples
  ---------
  >>> import tensorflow as tf
  >>> import numpy as np
  >>> from tensorlayer.layers import Input, Dense, Dropout
  >>> from tensorlayer.models import Model
  
  Define static model
  
  >>> class CustomModel(Model):
  >>>     def __init__(self):
  >>>         super(CustomModel, self).__init__()
  >>>         self.dense1 = Dense(n_units=800, act=tf.nn.relu, in_channels=784)
  >>>         self.dropout1 = Dropout(keep=0.8)
  >>>         self.dense2 = Dense(n_units=10, in_channels=800)
  >>>     def forward(self, x):
  >>>         z = self.dense1(x)
  >>>         z = self.dropout1(z)
  >>>         z = self.dense2(z)
  >>>         return z
  >>> M_dynamic = CustomModel()
  
  Define static model
  
  >>> ni = Input([None, 784])
  >>> nn = Dense(n_units=800, act=tf.nn.relu)(ni)
  >>> nn = Dropout(keep=0.8)(nn)
  >>> nn = Dense(n_units=10, act=tf.nn.relu)(nn)
  >>> M_static = Model(inputs=ni, outputs=nn, name="mlp")
  
  Get network information
  
  >>> print(M_static)
  ... Model(
  ...  (_inputlayer): Input(shape=[None, 784], name='_inputlayer')
  ...  (dense): Dense(n_units=800, relu, in_channels='784', name='dense')
  ...  (dropout): Dropout(keep=0.8, name='dropout')
  ...  (dense_1): Dense(n_units=10, relu, in_channels='800', name='dense_1')
  ... )
  
  Forwarding through this network
  
  >>> data = np.random.normal(size=[16, 784]).astype(np.float32)
  >>> outputs_d = M_dynamic(data)
  >>> outputs_s = M_static(data)
  
  Save and load weights
  
  >>> M_static.save_weights('./model_weights.h5')
  >>> M_static.load_weights('./model_weights.h5')
  
  Save and load the model
  
  >>> M_static.save('./model.h5')
  >>> M = Model.load('./model.h5')
  
  Convert model to layer
  
  >>> M_layer = M_static.as_layer()
