TensorFlow Estimator 2.0.1

TensorFlow Estimator 2.0 has been released with a private import of a symbol from TensorFlow master. However, that symbol does not exist on TensorFlow 2.0, due to a race condition regarding branch cuts.

This release patches TensorFlow Estimator to resolve this symbol not found error.

TensorFlow Estimator 2.0

Breaking changes

Both for Estimator and for main TensorFlow, tf.contrib has been deprecated, and functionality has been either migrated to the core TensorFlow API, to an ecosystem project such as https://www.github.com/tensorflow/addons or https://www.github.com/tensorflow/io, or removed entirely.

TensorFlow Estimator 1.15.1

This release is the same as 1.15.0 but we needed a new release to update the version number inside setup.py

Changes

• tf.keras.estimator.model_to_estimator now supports exporting to tf.train.Checkpoint format, which allows the saved checkpoints to be compatible with model.load_weights.
• "Fix tests in canned estimators."
• Expose Head as public API.
• Fixes critical bugs that help with DenseFeatures usability in TF2

TensorFlow Estimator 1.14.0

Changes

• Use tf.compat.v1.estimator.inputs instead of tf.estimator.inputs
• Replace contrib references with tf.estimator.experimental.* for APIs in early_stopping.py
• Determining the “correct” value of the --iterations_per_loop for TPUEstimator or DistributionStrategy continues to be a challenge for our users. We propose dynamically tuning the --iterations_per_loop variable, specifically for using TPUEstimator in training mode, based on a user target TPU execution time. Users might specify a value such as: --iterations_per_loop=300s, which will result in roughly 300 seconds being spent on the TPU between host side operations.
