Implementation of SPDNet [1], a Riemannian network for SPD matrix learning.

• Python 3.6+
• SciPy
• NumPy
• TensorFlow 2.0+
• TensorFlow RiemOpt

Configure gcloud to use Python 3:

gcloud config set ml_engine/local_python /usr/bin/python3

Train SPDNet locally on the Acted Facial Expression in Wild [2] dataset:

gcloud ai-platform local train \
       --module-name spdnet.task \
       --package-path . \
       -- \
       --data-dir data
       --job-dir ckpt
