text: Title: How do i resuse weights from one network in another?
  Body: lets say i have an autoencoder network
  
  ```
  encoder = tflearn.input_data(shape=[None, samples])
  encoder2 = tflearn.fully_connected(encoder, 30)
  decoder = tflearn.fully_connected(encoder2, samples, activation='tanh')
  ```
  
  how do i input my own values into layer encoder2 once the network is trained?
  
  In other words turn it into this network:
  
  ```
  encoder2 = tflearn.input_data(shape=[None, 30])
  decoder = tflearn.fully_connected(encoder2, samples)
  ```
