How to do it...

1. Once all the mentioned dependencies are installed, tensorflow can be installed from devtools directly using the install_github command as follows:

devtools::install_github("rstudio/tensorflow")

1. Before loading tensorflow in R, you need to set up the path for Python as the system environment variable. This can be done directly from the R environment, as shown in the following command:

Sys.setenv(TENSORFLOW_PYTHON="/usr/bin/python")
library(tensorflow)

If the Python tensorflow module is not installed, R will give the following error:

pip install tensorflow # Python 2.7 with no GPU support
pip3 install tensorflow # Python 3.x with no GPU support
pip install tensorflow-gpu # Python 2.7 with GPU support
pip3 install tensorflow-gpu # Python 3.x with GPU support
