Optimize lookup::GetLookupTable() for DT_RESOURCE tensors. This change makes four small optimizations to this hot method: 1. Cache the handle tensor dtype at kernel construction time to avoid resolving the named input twice. 2. Avoid calling HandleFromInput() (with a ResourceHandle* out parameter) and instead directly accessing the ResourceHandle, to save a copy of the strings inside the ResourceHandle. 3. Switching from Tensor::flat<ResourceHandle>()(0) to Tensor::scalar<ResourceHandle>()() performs slightly less work in validating the shape of the tensor (and as a bonus turns undefined behavior if the handle tensor *isn't* a scalar into a noisy CHECK). 4. Pass the (string literal) input_name as a StringPiece instead of a `const string&` to avoid temporary string creation each time the method is called.

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.
