does one know to to properly solve the polykia averaging issue mentioned? The solution mentioned doesn’t work I believe:

  
    
    
    Copying part of the weights reinforcement-learning
  
  
    I want to copy a part of the weight from one network to another. 
Using something like polyak averaging 
Example: 
weights_new = k*weights_old + (1-k)*weights_new 
This is required to implement DDPG. 
How can I do this?
