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 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.

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.

Install with Anaconda / Conda

The popular package manager Anaconda / Conda also comes equipped with TensorFlow as one of its packages.

Full information on TensorFlow with Anaconda / Conda can be found here.

Download and install Anaconda or the smaller Miniconda.

On Windows open the Start menu and open an Anaconda Command Prompt. On macOS or Linux open a terminal window. Use the default bash shell on macOS or Linux.

Choose a name for your TensorFlow environment, such as “tf”.

To install the current release of CPU-only TensorFlow, recommended for beginners:

conda create -n tf tensorflow
conda activate tf

Or, to install the current release of GPU TensorFlow on Linux or Windows:

conda create -n tf-gpu tensorflow-gpu
conda activate tf-gpu

TensorFlow is now installed and ready to use.

Alternatively to both Anaconda / Conda and pip installs, many contemporary Python IDEs, such as PyCharm, perform the Tensorflow install under the hood, adding the TensorFlow package to the virtual environment.

Try your first TensorFlow program

$ 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.
