TensorFlow Federated 0.2.0

Release 0.2.0

Major Features and Improvements

• Updated to use TensorFlow version 1.13.1.
• Implemented Federated SGD in tff.learning.build_federated_sgd_process().

Breaking Changes

• next() function of tff.utils.IteratedProcesss returned by build_federated_*_process() no longer unwraps single value tuples (always returns a tuple).

Bug Fixes

• Modify setup.py to require TensorFlow 1.x and not upgrade to 2.0 alpha.
• Stop unpacking single value tuples in next() function of objects returned by build_federated_*_process().
• Clear cached Keras sessions when wrapping Keras models to avoid referencing stale graphs.
