> In internal_keras_predict, we compile the model for every row. Starting from keras 1.0.3, keras predict does not need a compiled model. This will make our current predict code(which does not use SD) easier and hopefully slightly faster even with CPU. See more details here https://github.com/keras-team/keras/issues/3074
> Acceptance:
> 1. Validate that removing the compile code does not impact the accuracy of the results
> 2. Add new optional param named use_gpu in predict interface.
