working on fixes, for now we suggest using the legacy optimizers when
        using `ParameterServerStrategy`.
    *   **Timeout or performance loss.** We don't anticipate this to happen, but
        if you see such issues, please use the legacy optimizer, and file
        an issue in the Keras GitHub repo.

    The old Keras optimizer will never be deleted, but will not see any

   differentiating the energy function, the training must not backpropagate
   through the graph that generated the samples from the model.
*  Adversarial training, where no backprop should happen through the adversarial
   example generation process.
