models that process JPEG images will follow this flow: load image from disk, decode JPEG into a tensor, crop and pad, possibly flip and distort, and then batch. This flow is referred to as the inputpipeline. As GPUs and other hardware accelerators get faster, ...

在python和c++两种语言环境,将pytorch模型转化为tensorRT,能够帮助刚接触TensorRT的同学们快速上手。 一.简介 TensorRT是Nvidia公司出的能加速模型推理的框架,其实就是让你训练的模型在测试阶段的速度加快,比如你的模型测试一张图片的速度是50ms,那么用tensorRT加速的话,可...
🤗 Accelerate supports training on single/multiple GPUs using DeepSpeed. To use it, you don't need to change anything in your training code; you can set everything using justaccelerate config. However, if you desire to tweak your DeepSpeed related args from your Python script, we provide yo...
