TensorFlow is another open source library developed by the Google Brain Team to build numerical computation models using data flow graphs. The core of TensorFlow was developed in C++ with the wrapper in Python. The tensorflow package in R gives you access to the TensorFlow API composed of Python modules to execute computation models. TensorFlow supports both CPU- and GPU-based computations.

The tensorflow package in R calls the Python tensorflow API for execution, which is essential to install the tensorflow package in both R and Python to make R work. The following are the dependencies for tensorflow:

• Python 2.7 / 3.x
• R (>3.2)
• devtools package in R for installing TensorFlow from GitHub
• TensorFlow in Python
• pip
