"Keras is a high-level neural networks API, written in Python and capable of running on top of TensorFlow, CNTK, or Theano."[1]
If you are porting a Keras program to one of our clusters, you should follow our tutorial on the subject.
Installing
- Install TensorFlow, CNTK, or Theano in a Python virtual environment.
- Activate the Python virtual environment (named $HOME/tensorflow in our example).
[name@server ~]$ source $HOME/tensorflow/bin/activate
- Install Keras in your virtual environment.
(tensorflow)_[name@server ~]$ pip install keras
R package
This section details how to install Keras for R and use TensorFlow as the backend.
- Install TensorFlow for R by following these instructions.
- Follow the instructions from the parent section.
- Load the required modules.
[name@server ~]$ module load gcc/7.3.0 r/3.5.2
- Launch R.
[name@server ~]$ R
- In R, install the Keras package with
devtools.devtools::install_github('rstudio/keras')
You are then good to go. Do not call install_keras() in R, as Keras and TensorFlow have already been installed in your virtual environment with pip. To use the Keras package installed in your virtual environment, enter the following commands in R after the environment has been activated.
library(keras)
use_virtualenv(Sys.getenv('VIRTUAL_ENV'))
