This playbook, as the name entails, does the rest of the job of building TensorFlow.
This playbook does also setup a "builder" user (see roles/tensorflow/defaults/main.yml for name) and adds it to the wheel group (that is also changed to do password-less sudo) and changes its bashrc so Lmod is systematically loaded, so it can be used to do the build.
To that effect, it fetches dependencies first (see roles/tensorflow/tasks/main.yml for the precise task order), including OpenBLAS, HDF5, FFTW, GCC 8.3.0 and LMod from OpenHPC (See the Further Enhancements section), as well as openjdk8 for Bazel.
On the topic of Lmod, we are working on trying to find a way to install it and get it to work in the same bash script (without having to restart the bash session). BASH_ENV might be the trick.
