How do you save your trained model? #54

I've tried using pickle but it's unable to serialize the PILCO object after training.

Is there a builtin save method? Or does another kind of serialization work? Thanks.

Hi, there was function to save and load model in pull requests Utils pr #17 when pilco using TF1 and GP1, but now no attribute 'read_values' in GP2. Have you any solutions now?

Hello, We can save controller parameters (best_parameters variable in pilco) by using pickle and recreating the controller based on these parameters. Procedure :

  1. Save best_parameters of controller in pickle file during each iteration.
  2. Recreate controller using controller.py and these parameters.
  3. Use this controller on environment.

Example: For RBF controller best_parameters contains: DataX, DataY, and Lengthscales. With these parameters, we can recreate RBF controller.
