How to Use 2 (or more) NVIDIA GPUs to Speed Keras/TensorFlow Deep Learning Training

Dual GPU systems are becoming much more of a “deep learning thing” than a “gamer thing”. But what will two (or more) GPUs on a single system actually get you? In this video, I show how to actually use two GPU’s and how it can nearly cut your training time in half; under the right circumstances. We make use of a Lenovo P920 with dual Quadro GTX 8000 GPUs.
