Support interprocedural constant meta-information propagation for compilation This CL does two things: 1) Supports inter-procedural constant information propagation, across PartitionedCall and StatefulPartitionedCall. 2) Done naively, (1) leads to exponential number of calls, as each function will be reinlined for each (indirect) caller. In order to address this performance issue, we cache the argument indices which need to be constant, and attach that information to the Graph object. This might require some clarification: a) Caching in a passed map would not work, as duplication of constant propagation for each top-level caller is still prohibitively expensive. b) Caching in a global object would not work, as graphs are created and destroyed during transformations. c) Caching this meta-information on a `Graph` object has an added benefit that we no longer perform the same constant propagation many times (a lot of compilation passes call BackwardsConstAnalysis, and previously all this work had to be repeated).

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.
