YOLOv5s量化模型 Python部署示例
本目录下提供的infer.py,可以帮助用户快速完成YOLOv5量化模型在CPU/GPU上的部署推理加速.
部署准备
FastDeploy环境准备
-
- 软硬件环境满足要求，参考FastDeploy环境要求
-
- FastDeploy Python whl包安装，参考FastDeploy Python安装
量化模型准备
-
- 用户可以直接使用由FastDeploy提供的量化模型进行部署.
-
- 用户可以使用FastDeploy提供的一键模型自动化压缩工具,自行进行模型量化, 并使用产出的量化模型进行部署.
以量化后的YOLOv5s模型为例, 进行部署
