YOLOv7量化模型 C++部署示例

本目录下提供的infer.cc,可以帮助用户快速完成YOLOv7量化模型在CPU/GPU上的部署推理加速.

部署准备

FastDeploy环境准备

1. 软硬件环境满足要求，参考FastDeploy环境要求
1. FastDeploy Python whl包安装，参考FastDeploy Python安装

量化模型准备

1. 用户可以直接使用由FastDeploy提供的量化模型进行部署.
1. 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YOLOv7模型为例, 进行部署

在本目录执行如下命令即可完成编译,以及量化模型部署.支持此模型需保证FastDeploy版本0.7.0以上(x.x.x>=0.7.0)

mkdir build
cd build
# 下载FastDeploy预编译库，用户可在上文提到的`FastDeploy预编译库`中自行选择合适的版本使用
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
tar xvf fastdeploy-linux-x64-x.x.x.tgz
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
make -j
