To understand the optimization techniques Facebook has implemented to improve the performance and ef- ciency of inference we present two case studies. Deploying to Android or iOS does require a non-trivial amount of work in TensorFlow. sh that Nov 19, 2019 · Running Machine Learning code on mobile devices is the next big thing. The torch. 3 comes with the ability to quantize a model for inference on to either server or mobile devices. This is because by default, PyTorch has built-in support for doing auto-differentiation, which is also known as autograd. However, currently AWS lambda and other serverless compute functions usually run on the CPU. This post is part of our PyTorch for Beginners series 1. pytorch mobile inference
