PaddleClas 量化模型 Python部署示例

本目录下提供的infer.cc,可以帮助用户快速完成PaddleClas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提供的一键模型量化工具,自行进行模型量化, 并使用产出的量化模型进行部署.(注意: 推理量化后的分类模型仍然需要FP32模型文件夹下的inference_cls.yaml文件, 自行量化的模型文件夹内不包含此yaml文件, 用户从FP32模型文件夹下复制此yaml文件到量化后的模型文件夹内即可.)

以量化后的ResNet50_Vd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.

mkdir build
cd build
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-0.2.0.tgz
tar xvf fastdeploy-linux-x64-0.2.0.tgz
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-0.2.0
make -j
