optimizer to update different parts of model in multiple stages,
please call `optimizer.build(model.trainable_variables)` before the

* **Performance regression on `ParameterServerStrategy`.** This could be
significant if you have many PS servers. We are aware of this issue and
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.
