TensorFlow 2.1.0 rc0 release

TensorFlow 2.1.0 rc0 released, TensorFlow 2.1 will be the last to support Python version TF 2. Python2 support will be 1 January 2020 officially ended, TensorFlow also from that date to stop supporting Python 2, and will no longer be expected to release a new version in 2019.

Key features and improvements are as follows:

  • tensorflow pip package is now included by default for Linux and Windows GPU support (and tensorflow-gpu same). It can run on machines with and without NVIDIA GPU's. tensorflow-gpu is still available for users concerned about the size of the package, the package can be downloaded only CPU on tensorflow-cpu.
  • tf.keras
    • Model.fit_generatorModel.evaluate_generatorModel.predict_generatorModel.train_on_batchModel.test_on_batch, And  Model.predict_on_batch methods are now respected run_eagerly property, and the case will be used to run correctly tf.function default.
    • Model.fit_generatorModel.evaluate_generatorAnd  Model.predict_generator it is deprecated endpoints. They contain Model.fit, Model.evaluate and Model.predict, they now supports the generation and sequence.
    • As long as in the range of building the model, you can be Keras .compile .fit .evaluate .predict and placed outside DistributionStrategy range.
    • Keras model.load_weights now accept skip_mismatch as a parameter. It is available in external Keras, it has been copied to the tf.keras.
    • Introduced TextVectorization layer that the original string as input, and for text normalization, labeled, n-gram index generation and vocabulary.
    • Cloud TPU Pod provides, .fit, experimental support for Keras .compile .evaluate and .predict of.
    • TPU is now cloud enabled automatic external compiler. Tf.summary This makes it easier to use with Cloud TPU.
    • Cloud TPU support dynamic batch sizes and with DistributionStrategy of Keras.
    • GPU and Cloud TPU provides experimental support for mixing accuracy.
    • TensorFlow  Model Garden  offers many popular models Keras reference implementation.
  • tf.data
    • Change tf.data dataset recataloged + distribution strategies to improve performance. Please note that the behavior is slightly different data sets, since relabeled data sets base will always be a multiple of the number of copies.
  • TensorRT
    • Now supported and enabled by default TensorRT 6.0. It adds support for more TensorFlow operations, including Conv3D, Conv3DBackpropInputV2, AvgPool3D, MaxPool3D, ResizeBilinear and ResizeNearestNeighbor. In addition, TensorFlow-TensorRT python conversion API to export to tf.experimental.tensorrt.Converter.
