[tf.data] Improvements to static optimizations. This CL: 1) Introduces a mechanism for identifying function graphs associated with tf.data user defined functions and uses it to exclude such graphs from Grappler optimizations applied by TensorFlow optimizer to the entire function library runtime (in graph mode). 2) Extends the set of Grappler optimizations applied by tf.data optimizer to function graphs associated with tf.data user-defined functions to match the default TensorFlow optimizer. 3) Introduces a new tf.data rewrite, which sets the device of Conv2D without explicit device assignment to CPU. The layout optimization assumes that all ops without explicit device assignment will be placed on GPU (if possible), which is not true for ops without tf.data user-defined function and result in incorrect layout optimization.

TensorFlow is an end-to-end open source platform for machine learning. It has a comprehensive, flexible ecosystem of tools, libraries, and community resources that lets researchers push the state-of-the-art in ML and developers easily build and deploy ML-powered applications.
TensorFlow was originally developed by researchers and engineers working on the Google Brain team within Google's Machine Intelligence Research organization to conduct machine learning and deep neural networks research. The system is general enough to be applicable in a wide variety of other domains, as well.
TensorFlow provides stable Python and C++ APIs, as well as non-guaranteed backward compatible API for other languages.
Keep up-to-date with release announcements and security updates by subscribing to announce@tensorflow.org. See all the mailing lists.
See the TensorFlow install guide for the pip package, to enable GPU support, use a Docker container, and build from source.
To install the current release, which includes support for CUDA-enabled GPU cards (Ubuntu and Windows):
$ pip install tensorflow
A smaller CPU-only package is also available:
$ pip install tensorflow-cpu
To update TensorFlow to the latest version, add --upgrade flag to the above commands.
Nightly binaries are available for testing using the tf-nightly and tf-nightly-cpu packages on PyPi.
$ python
>>> import tensorflow as tf >>> tf.add(1, 2).numpy() 3 >>> hello = tf.constant('Hello, TensorFlow!') >>> hello.numpy() b'Hello, TensorFlow!'
For more examples, see the TensorFlow tutorials.
