* | Makes sure Keras Layer's `__call__` is always used in Eager.Gravatar A. Unique TensorFlower2018-10-04
| | | | | | | | | | | | | | | | | | Currently if a Layer is invoked with the Functional API in Eager, `__call__` is only used during setup, and thereafter `call` is used internally. This limits the ability to add pre/post processing steps to `call` in Eager in the future. Additionally, the Subclassed Model API already always uses `__call__` in Eager. PiperOrigin-RevId: 215778408

* | | | Simplify eager/graph Layer.losses conditionalsGravatar Allen Lavoie2018-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes an issue where losses created while executing eagerly were returned as unevaluated lambdas in a defun. Lazily evaluates Layer losses by default when possible. Even when graph building this is generally a better thing to do (e.g. losses called in a while_loop). Allows calls to Layer.add_loss when executing eagerly, but only for losses which are not conditional on inputs (no activity regularizers). PiperOrigin-RevId: 214947108
