[tf.data] Fix bugs in dataset hashing and add CheckGraphsEqual function. The bugs were: 1. If an AttrValue contained a list of functions, we would hash the AttrValue using DeterministicProtoHash64. This would hash the function name, which is not stable and should not be hashed. This CL updates AttrValue hashing to handle lists of functions specially. 2. We perform a DFS at the start to decide which edges to ignore to avoid cycles. This DFS needs to be deterministic, but previously it relied on the ordering of control dependencies, which should be treated as unordered. This CL avoids recursing into control dependencies, so that they cannot introduce cycles. This CL also adds a CheckGraphsEqual utility to help understand why two graphs might have different hash codes. Lastly, this CL organizes our hashing code by moving it from dataset_utils to its own hash_utils file. PiperOrigin-RevId: 333111866 Change-Id: Ic4a79c743a9c1d8e743f6a10bb2b578ad6e1246e

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.
