"""Interface that provides access to Keras dependencies.
|
|
|
|
This library is a common interface that contains Keras functions needed by
|
|
TensorFlow and TensorFlow Lite and is required as per the dependency inversion
|
|
principle (https://en.wikipedia.org/wiki/Dependency_inversion_principle). As per
|
|
this principle, high-level modules (eg: TensorFlow and TensorFlow Lite) should
|
|
not depend on low-level modules (eg: Keras) and instead both should depend on a
|
|
common interface such as this file.
