Release 1.10.0

Major Features And Improvements

  • The tf.lite runtime now supports complex64.
  • Initial Bigtable integration for tf.data.
  • Improved local run behavior in tf.estimator.train_and_evaluate which does not reload checkpoints for evaluation.
  • RunConfig now sets device_filters to restrict how workers and PS can communicate. This can speed up training and ensure clean shutdowns in some situations. But if you have jobs that require communication between workers, you will have to set custom session_options in your RunConfig.
  • Moved Distributions and Bijectors from tf.contrib.distributions to Tensorflow Probability (TFP). tf.contrib.distributions is now deprecated and will be removed by the end of 2018.
  • Adding new endpoints for existing tensorflow symbols. These endpoints are going to be the preferred endpoints going forward and may replace some of the existing endpoints in the future. See below for the complete list. New symbols have been added to the following modules: tf.debugging, tf.dtypes, tf.image, tf.io, tf.linalg, tf.manip, tf.math, tf.quantization, tf.strings

Breaking Changes

  • Prebuilt binaries are now (as of TensorFlow 1.10) built against NCCL 2.2 and no longer include NCCL in the binary install. TensorFlow usage with multiple GPUs and NCCL requires upgrade to NCCL 2.2. See updated install guides: Installing TensorFlow on Ubuntu and Install TensorFlow from Sources.
  • Starting from TensorFlow 1.11, Windows builds will use Bazel. Therefore, we will drop official support for cmake.

Bug Fixes and Other Changes

  • tf.data:
    • tf.contrib.data.group_by_reducer() is now available via the public API.
    • tf.contrib.data.choose_from_datasets() is now available via the public API.
    • Adding drop_remainder argument to tf.data.Dataset.batch() and tf.data.Dataset.padded_batch(), deprecating tf.contrib.data.batch_and_drop_remainder() and tf.contrib.data.padded_batch_and_drop_remainder().
  • tf.estimator:
    • Estimators now use custom savers included in EstimatorSpec scaffolds for saving SavedModels during export.
    • EstimatorSpec will now add a default prediction output for export if no export_output is provided, eliminating the need to explicitly include a PredictOutput object in the model_fn for simple use-cases.
    • Support sparse_combiner in canned Linear Estimators.
    • Added batch normalization to DNNClassifier, DNNRegressor, and DNNEstimator.
    • Adding ranking support for boosted trees.
    • Adding center bias option for boosted trees.
  • Add synchronization and aggregation args to get_variable(). These args will be used for distributed variables.
  • Add synchronization and aggregation args to the layer add_weight() API. These args will be used for distributed variables.
  • tf.losses.* do not add to the global collection when executing eagerly (to avoid leaking memory).
  • Support different summary and checkpoint directories in tf.train.MonitoredTrainingSession().
  • Added IndRNN, IndyGRU, and IndyLSTM cells to tf.contrib.rnn.
  • Add safe static factory functions for SparseTensor and convert all CHECKs to DCHECKs. Using the constructor directly is unsafe and deprecated.
  • Make the Bigtable client connection pool configurable & increase the default # of connections for performance.
  • Added derivative of tf.random_gamma with respect to the alpha parameter.
  • Added derivative of tf.igamma(a, x) and tf.igammac(a, x) with respect to a.
  • Modified Bessel functions of order zero and one.
  • Add FillTriangular Bijector to create triangular matrices.
  • Added support for Type III DCT, and tf.spectral.idct(type=2|3).
  • Correctly handle CuDNN RNN weight loaded when nest in TimeDistributed.
  • Adding per-element weight support for WALSComputePartialLhsAndRhsOp.
  • ZerosLike and OnesLike ops treated as constants by Graph Transform Tool.
  • Gamma distribution and the derived distributions (Beta, Dirichlet, Student's t, inverse Gamma) now fully reparameterized.
  • Java: Experimental wrapper classes to make graph generation easier. Thanks @karllessard and @kbsriram
  • Build & link in secure gRPC components (switch from the insecure grpc dependency to secure grpc dependency).
  • Adding new endpoints for existing tensorflow symbols. These endpoints are going to be the preferred endpoints going forward and may replace some of the existing endpoints in the future. List of new endpoints:
    • New endpoints in tf.image namespace: tf.image.extract_image_patches
