Fix affine data copy generation corner cases/bugs - the [begin, end) range identified for copying could end in between the block, which makes hoisting invalid in some cases. Change the range identification to always end with end of block. - add test case to exercise these (with fast mem capacity set to minimal so that single element memref buffers are generated at the innermost loop) - the location of begin/end of the block range for data copying was being confused with the insert points for copy in and copy out code. In cases, where we choose to hoist transfers, these are separate. - when copy loops are single iteration ones, promote their bodies at the end of the pass. - change default fast mem space to 1 (setting it to zero made it generate DMA op's that won't verify in the default case - since the DMA ops have a check for src/dest memref spaces being different).

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 for the purposes of conducting 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 backwards 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 for CPU-only:
$ pip install tensorflow
Use the GPU package for CUDA-enabled GPU cards:
$ pip install tensorflow-gpu
Nightly binaries are available for testing using the tf-nightly and tf-nightly-gpu packages on PyPi.
$ python
>>> import tensorflow as tf >>> tf.enable_eager_execution() >>> tf.add(1, 2).numpy() 3 >>> hello = tf.constant('Hello, TensorFlow!') >>> hello.numpy() 'Hello, TensorFlow!'
For more examples, see the TensorFlow tutorials.
