tensorflow/tensorflow
An Open Source Machine Learning Framework for Everyone
📖 项目介绍
Documentation |
------------------- |
 |
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 within
the Machine Intelligence team at Google Brain to conduct research in machine
learning and neural networks. However, the framework is versatile enough to be
used in other areas as well.
TensorFlow provides stable Python
and C++ APIs, as well as a
non-guaranteed backward compatible API for
other languages.

Install
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
Other devices (DirectX and MacOS-metal) are supported using
Device Plugins.
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.*
#### Try your first TensorFlow program
shell
$ python
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.
Contribution guidelines
If you want to contribute to TensorFlow, be sure to review the
Contribution Guidelines. This project adheres to TensorFlow's
Code of Conduct. By participating, you are expected to
uphold this code.
We use GitHub Issues for
tracking requests and bugs, please see
TensorFlow Forum for general questions and
discussion, and please direct specific questions to
Stack Overflow.
The TensorFlow project strives to abide by generally accepted best practices in
open-source software development.
Patching guidelines
Follow these steps to patch a specific version of TensorFlow, for example, to
apply fixes to bugs or security vulnerabilities:
* Clone the TensorFlow repository and switch to the appropriate branch for
your desired version—for example, r2.8 for version 2.8.
* Apply the desired changes (i.e., cherry-pick them) and resolve any code
conflicts.
* Run TensorFlow tests and ensure they pass.
* Build the TensorFlow pip
package from source.
Continuous build status
You can find more community-supported platforms and configurations in the
TensorFlow SIG Build Community Builds Table.
