## Install prerequisites (rhel)

yum install numpy python-devel python-wheel python-mock

## Install Bazel

wget https://github.com/bazelbuild/bazel/releases/download/0.4.5/bazel-0.4.5-dist.zip

unzip bazel-0.4.-dist.zip -d bazel

## Modify bazel WORKSPACE

cd bazel

Modify WORKSPACE (Optinal step to avoid warnings)

    from workspace(name = "io_bazel")

    to   workspace(name = "bazel_tools")

## Build bazel

./compile.sh

## Install cuda 8.0

https://developer.nvidia.com/cuda-downloads

## Install cuDNN

sudo tar -xvf cudnn-8.0-linux-ppc64le-v5..tgz -C /usr/local/

https://developer.nvidia.com/compute/machine-learning/cudnn/secure/v6/prod/8.0_20170427/cudnn-8.0-linux-ppc64le-v6.0-tgz
