Fix bug in alias buffer donation for allocate_xla_tensors case. If allocate_xla_tensors was set and aliasing was enabled for resource variable updates, we would crash with double free of the donated buffer. This change: * Updates the buffer donation logic for the allocate_xla_tensors case to be consistent with the non-allocate_xla_tensors case to avoid the double free. * Attempts to better document the buffer ownership that appears to be happening in practice. * Updates the case where host shape and device shape are unequal to use the same buffer ownership logic as the case when they are equal, though it's not clear if that case occurs in practice. * Enables aliasing for resource variable updates in the allocate_xla_tensors case to improve test coverage. * Re-enables a couple of tests that were disabled because of the double free.

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.
