Example of PaddleClas models Python multi-thread/multi-process Deployment

Before deployment, two steps require confirmation

• 1. Software and hardware should meet the requirements. Please refer to FastDeploy Environment Requirements
• 2. Install the FastDeploy Python whl package. Please refer to FastDeploy Python Installation

This directory provides example file multi_thread_process.py to fast deploy multi-thread/multi-process ResNet50_vd on CPU/GPU and GPU accelerated by TensorRT. The script is as follows

# Download deployment example code
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd  FastDeploy/tutorials/multi_thread/python

# Download the ResNet50_vd model file and test images
wget https://bj.bcebos.com/paddlehub/fastdeploy/ResNet50_vd_infer.tgz
tar -xvf ResNet50_vd_infer.tgz
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
