Code and workflow for building OpenFace in Docker Hub and modifying it with Singularity Hub for use with PSU ACI HPC clusters.

From ACI, executing the following code should create an OpenFace image.

singularity pull shub://d-bohn/openface_ics:latest

The OpenFace docker image was built from scratch on docker hub following the documentation provided by it's maintainers.

The OpenFace singularity image was built using the docker image base and converting it to a singularity image via singularity hub.

Setup for linking Github with Docker Hub and Singularity Hub can be found here:

• docker Hub
• Singularity Hub

The Singularity file specifies creating a Singularity-compatible image from the docker image, as well as adding access to folders within ACI, specifically:

# ACI mappings so you can access your files.
mkdir -p /storage/home
mkdir -p /storage/work
mkdir -p /gpfs/group
mkdir -p /gpfs/scratch
mkdir -p /var/spool/torque

• The OpenFace docker image is large (> 6GB). It is built on Ubuntu 18.04. Not sure if it can be reduced in size as the executables rely on several large libraries.

• Several important updates for faciallandmarkdetector are hosted on the maintainer's cloud account. Might be prudent to download them separately and/or include them in the repository.

• Some functionality for real-time video viewing is not available when run in a container (at least not as of now).
