What it does
Before training, data must be loaded, decoded, cropped and resized, and doing this on the main processor can slow everything down. DALI moves this work onto NVIDIA graphics cards.
It works with PyTorch, TensorFlow and PaddlePaddle.
Who it's for
Engineers training or running deep-learning models at speed.
