Introduce attributes that specify the final ABI for a spirv::ModuleOp. To simplify the lowering into SPIR-V, while still respecting the ABI requirements of SPIR-V/Vulkan, split the process into two 1) While lowering a function to SPIR-V (when the function is an entry point function), allow specifying attributes on arguments and function itself that describe the ABI of the function. 2) Add a pass that materializes the ABI described in the function. Two attributes are needed. 1) Attribute on arguments of the entry point function that describe the descriptor_set, binding, storage class, etc, of the spv.globalVariable this argument will be replaced by 2) Attribute on function that specifies workgroup size, etc. (for now only workgroup size). Add the pass -spirv-lower-abi-attrs to materialize the ABI described by the attributes. This change makes the SPIRVBasicTypeConverter class unnecessary and is removed, further simplifying the SPIR-V lowering path.

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 for CPU-only:
$ pip install tensorflow
Use the GPU package for CUDA-enabled GPU cards (Ubuntu and Windows):
$ 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.add(1, 2).numpy() 3 >>> hello = tf.constant('Hello, TensorFlow!') >>> hello.numpy() 'Hello, TensorFlow!'
For more examples, see the TensorFlow tutorials.
