[XLA:GPU] Simplify heuristics for promotion to int8x32. Previously, we would upgrade to int8x32 if doing so did not result in a > 2.5x increase in the input/filter/output size of the conv. Now we only consider the input/output sizes. Sometimes the filter increases by more than 2.5x and we observe that it's still worthwhile to pad. Anyway I think this makes more sense, since the increase in the filter size is really a function of the input/output increases. As a result we're able to switch the heuristic to the more intuitive "don't expand input/output by 2x or more". PiperOrigin-RevId: 390144519 Change-Id: I96cdb0a95dc627157cdcd02d4eb1c593cedd148f

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.
