TensorFlow for R


TensorFlow for R

TensorFlow™ is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API.

The TensorFlow API is composed of a set of Python modules that enable constructing and executing TensorFlow graphs. The tensorflow package provides access to the complete TensorFlow API from within R.


First, install the main TensorFlow distribution from here:

If you install TensorFlow within a virtualenv environment you'll need to be sure to use that same environment when loading the tensorflow R package (see below for details on how to do this).

Next, install the tensorflow R package from GitHub as follows:


Locating TensorFlow

When it is loaded the tensorflow R package scans the system for the version of python where TensorFlow is installed. If automatic detection doesn't work or if you want to exercise more control over which version(s) of python and TensorFlow are used you can specify an explicit TENSORFLOW_PYTHON environment variable to force probing for TensorFlow within a specific version of python, for example:


You can also specify Python virtualenvs or Conda envs via the use_python functions documented here.

Verifying Installation

You can verify that your installation is working correctly by running this script:

sess = tf$Session()
hello <- tf$constant('Hello, TensorFlow!')


See the package website for additional details on using the TensorFlow API from R:

See the TensorFlow API reference for details on all of the modules, classes, and functions within the API:

The tensorflow package provides code completion and inline help for the TensorFlow API when running within the RStudio IDE. In order to take advantage of these features you should also install the current Preview Release of RStudio.
