二、Ubuntu18.04环境配置
如果您对tensorrt不是很熟悉,请务必保持下面库版本一致。
2.1 安装工具链和opencv
sudoapt-get update
sudoapt-getinstall build-essential
sudoapt-getinstallgitsudoapt-getinstall gdb
sudoapt-getinstall cmake
sudoapt-getinstall libopencv-dev
# pkg-config --modversion opencv
2.2 安装Nvidia相关库
注:Nvidia相关网站需要注册账号。
2.2.1 安装Nvidia显卡驱动
ubuntu-drivers devices
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-driver-470-server # for ubuntu18.04
nvidia-smi
2.2.2 安装 cuda11.3
- 进入链接: https://developer.nvidia.com/cuda-toolkit-archive
- 选择:CUDA Toolkit 11.3.0(April 2021)
- 选择:[Linux] -> [x86_64] -> [Ubuntu] -> [18.04] -> [runfile(local)] 在网页你能看到下面安装命令,我这里已经拷贝下来:
wget https://developer.download.nvidia.com/compute/cuda/11.3.0/local_installers/cuda_11.3.0_465.19.01_linux.run
sudo sh cuda_11.3.0_465.19.01_linux.run
cuda的安装过程中,需要你在bash窗口手动作一些选择,这里选择如下:
- select:[continue] -> [accept] -> 接着按下回车键取消Driver和465.19.01这个选项,如下图(it is important!) -> [Install] bash窗口提示如下表示安装完成
#===========#= Summary =#===========#Driver: Not Selected#Toolkit: Installed in /usr/local/cuda-11.3/#......
把cuda添加到环境变量:
vim ~/.bashrc
把下面拷贝到 .bashrc里面
# cuda v11.3export PATH=/usr/local/cuda-11.3/bin${PATH:+:${PATH}}export LD_LIBRARY_PATH=/usr/local/cuda-11.3/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}export CUDA_HOME=/usr/local/cuda-11.3
刷新环境变量和验证
source ~/.bashrc
nvcc -V
bash窗口打印如下信息表示cuda11.3安装正常
nvcc: NVIDIA (R) Cuda compiler driver<br>
Copyright (c) 2005-2021 NVIDIA Corporation<br>
Built on Sun_Mar_21_19:15:46_PDT_2021<br>
Cuda compilation tools, release 11.3, V11.3.58<br>
Build cuda_11.3.r11.3/compiler.29745058_0<br>
2.2.3 安装 cudnn8.2
- 进入网站:https://developer.nvidia.com/rdp/cudnn-archive
- 选择: Download cuDNN v8.2.0 (April 23rd, 2021), for CUDA 11.x
- 选择: cuDNN Library for Linux (x86_64)
- 你将会下载这个压缩包: “cudnn-11.3-linux-x64-v8.2.0.53.tgz”
# 解压tar -zxvf cudnn-11.3-linux-x64-v8.2.0.53.tgz
将cudnn的头文件和lib拷贝到cuda11.3的安装目录下:
sudocp cuda/include/cudnn.h /usr/local/cuda/include/
sudocp cuda/lib64/libcudnn* /usr/local/cuda/lib64/
sudochmod a+r /usr/local/cuda/include/cudnn.h
sudochmod a+r /usr/local/cuda/lib64/libcudnn*
2.2.4 下载 tensorrt8.4.2.4
本教程中,tensorrt只需要下载\、解压即可,不需要安装。
- 进入网站: https://developer.nvidia.cn/nvidia-tensorrt-8x-download
- 把这个打勾: I Agree To the Terms of the NVIDIA TensorRT License Agreement
- 选择: TensorRT 8.4 GA Update 1
- 选择: TensorRT 8.4 GA Update 1 for Linux x86_64 and CUDA 11.0, 11.1, 11.2, 11.3, 11.4, 11.5, 11.6 and 11.7 TAR Package
- 你将会下载这个压缩包: “TensorRT-8.4.2.4.Linux.x86_64-gnu.cuda-11.6.cudnn8.4.tar.gz”
# 解压tar -zxvf TensorRT-8.4.2.4.Linux.x86_64-gnu.cuda-11.6.cudnn8.4.tar.gz
# 快速验证一下tensorrt+cuda+cudnn是否安装正常cd TensorRT-8.4.2.4/samples/sampleMNIST
makecd../../bin/
导出tensorrt环境变量(it is important!),注:将LD_LIBRARY_PATH:后面的路径换成你自己的!后续编译onnx模型的时候也需要执行下面第一行命令
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/xxx/temp/TensorRT-8.4.2.4/lib
./sample_mnist
bash窗口打印类似如下图的手写数字识别表明cuda+cudnn+tensorrt安装正常
2.2.5 下载仓库TensorRT-Alpha并设置
git clone https://github.com/FeiYull/tensorrt-alpha
设置您自己TensorRT根目录:
git clone https://github.com/FeiYull/tensorrt-alpha
cd tensorrt-alpha/cmake
vim common.cmake
# 在文件common.cmake中的第20行中,设置成你自己的目录,别和我设置一样的路径eg:# set(TensorRT_ROOT /root/TensorRT-8.4.2.4)
三、YOLOv8模型部署
3.1 获取YOLOv8onnx文件
直接在网盘下载 weiyun or google driver 或者使用如下命令导出onnx:
# 🔥 yolov8 官方仓库: https://github.com/ultralytics/ultralytics# 🔥 yolov8 官方教程: https://docs.ultralytics.com/quickstart/# 🚀TensorRT-Alpha will be updated synchronously as soon as possible!# 安装 yolov8
conda create -n yolov8 python==3.8 -y
conda activate yolov8
pip install ultralytics==8.0.5
pip install onnx
# 下载官方权重(".pt" file)
https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n.pt
https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8s.pt
https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8m.pt

https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8x.pt
https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8x6.pt
导出 onnx:
# 640

yolo mode=export model=yolov8s.pt format=onnx dynamic=True #simplify=True
yolo mode=export model=yolov8m.pt format=onnx dynamic=True #simplify=True
yolo mode=export model=yolov8l.pt format=onnx dynamic=True #simplify=True
yolo mode=export model=yolov8x.pt format=onnx dynamic=True #simplify=True# 1280
yolo mode=export model=yolov8x6.pt format=onnx dynamic=True #simplify=True
3.2 编译 onnx
# 把你的onnx文件放到这个路径:tensorrt-alpha/data/yolov8cd tensorrt-alpha/data/yolov8
# 请把LD_LIBRARY_PATH:换成您自己的路径。export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/TensorRT-8.4.2.4/lib
# 640../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8n.onnx --saveEngine=yolov8n.trt --buildOnly --minShapes=images:1x3x640x640 --optShapes=images:4x3x640x640 --maxShapes=images:8x3x640x640

cd tensorrt-alpha/yolov8
mkdir build
cd build
cmake ..make -j10
