Fail definition events if `CreateBuffersForAsyncHostToDevice` fails in the middle. Previously, if `CreateBuffersForAsyncHostToDeviceCleanupAfterFailure` failed after successfully allocating some of the buffers (e.g. we OOMed on allocating the last of N buffers), it would leave definition events for the successfully allocated buffers unfulfilled forever. This can lead to hangs. In the instance we saw, the deletion of these leaked buffers would block on their never-fulfilled definitions, which then caused subsequent allocations to block forever.

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 within the Machine Intelligence team at Google Brain to conduct research in machine learning and neural networks. However, the framework is versatile enough to be used in other areas as well.
TensorFlow provides stable Python and C++ APIs, as well as a 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
Other devices (DirectX and MacOS-metal) are supported using Device Plugins.
A smaller CPU-only TensorFlow package is also available:
pip install tensorflow-cpu
To update TensorFlow to the latest version, add the --upgrade flag to the commands above.
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.
