Set default device info if device type is neither CPU nor GPU.

OpLevelCostEstimator::GetDeviceInfo() returns GFLOPs/sec and GB/sec of
the assumed machine, but currently it assumes the device type is either CPU
or GPU. We didn't expect other device types would be passed during the Grappler
optimization as transfer operations such as _Send and _Recv are added when
a graph actually runs. In some occasions, we encountered the input graph
includes _HostSend op (it is possible that the graph includes _Send or _Recv
ops; that happened in some test cases).

Device type not CPU / GPU currently causes crash; to avoid such a case, we
assume unknown device type as transfer operations over PCIe; setting
default PCIe x16 gen3 bandwidth to avoid crash.

As the GetDeviceInfo() method is virtual, one may override this method
if more precise device info is needed.

Documentation

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.

Install

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.

Try your first TensorFlow program

$ 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.
