ubuntu18.04 yolov8 tensorrt模型加速部署【实战】
TensorRT-Alpha基于tensorrt+cuda c++实现模型end2end的gpu加速,支持win10、linux,在2023年已经更新模型:YOLOv8, YOLOv7, YOLOv6, YOLOv5, YOLOv4, YOLOv3, YOLOX, YOLOR,pphumanseg,u2net,EfficientDet。
Windows10教程正在制作,可以关注仓库:https://github.com/FeiYull/TensorRT-Alpha
一、加速结果展示
1.1 性能速览
🚀快速看看yolov8n 在移动端RTX2070m(8G)的新能表现:
model | video resolution | model input size | GPU Memory-Usage | GPU-Util |
---|---|---|---|---|
yolov8n | 1920x1080 | 8x3x640x640 | 1093MiB/7982MiB | 14% |
下图是yolov8n的运行时间开销,单位是ms:

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
sudo apt-get update sudo apt-get install build-essential sudo apt-get install git sudo apt-get install gdb sudo apt-get install cmake
sudo apt-get install libopencv-dev # pkg-config --modversion opencv
2. 安装Nvidia相关库
注:Nvidia相关网站需要注册账号。
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 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 v11.3 export 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>
2.3 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:
sudo cp cuda/include/cudnn.h /usr/local/cuda/include/ sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64/ sudo chmod a+r /usr/local/cuda/include/cudnn.h sudo chmod a+r /usr/local/cuda/lib64/libcudnn*
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 make cd ../../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=$LD_LIBRARY_PATH:/home/xxx/temp/TensorRT-8.4.2.4/lib ./sample_mnist
bash窗口打印类似如下图的手写数字识别表明cuda+cudnn+tensorrt安装正常
三、YOLOv8模型部署
3.1 下载仓库TensorRT-Alpha
git clone https://github.com/FeiYull/tensorrt-alpha
3.2 获取onnx文件
直接在网盘下载 weiyun or google driver 或者使用如下命令导出onnx:
# 🔥 yolov8 官方仓库: https://github.com/ultralytics/ultralytics # 🔥 yolov8 官方教程: https://docs.ultralytics.com/quickstart/ # 🚀TensorRT-Alpha will be updated synchronously as soon as possible! # 安装 yolov8 conda create -n yolov8 python==3.8 -y conda activate yolov8 pip install ultralytics==8.0.5 pip install onnx # 下载官方权重(".pt" file) https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8n.pt https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8s.pt https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8m.pt https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8l.pt https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8x.pt https://github.com/ultralytics/assets/releases/download/v0.0.0/yolov8x6.pt
导出 onnx:
# 640 yolo mode=export model=yolov8n.pt format=onnx dynamic=True #simplify=True yolo mode=export model=yolov8s.pt format=onnx dynamic=True #simplify=True yolo mode=export model=yolov8m.pt format=onnx dynamic=True #simplify=True yolo mode=export model=yolov8l.pt format=onnx dynamic=True #simplify=True yolo mode=export model=yolov8x.pt format=onnx dynamic=True #simplify=True # 1280 yolo mode=export model=yolov8x6.pt format=onnx dynamic=True #simplify=True
3.3 编译 onnx
# 把你的onnx文件放到这个路径:tensorrt-alpha/data/yolov8 cd tensorrt-alpha/data/yolov8 # 请把LD_LIBRARY_PATH:换成您自己的路径。 export LD_LIBRARY_PATH=$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 ../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8s.onnx --saveEngine=yolov8s.trt --buildOnly --minShapes=images:1x3x640x640 --optShapes=images:4x3x640x640 --maxShapes=images:8x3x640x640 ../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8m.onnx --saveEngine=yolov8m.trt --buildOnly --minShapes=images:1x3x640x640 --optShapes=images:4x3x640x640 --maxShapes=images:8x3x640x640 ../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8l.onnx --saveEngine=yolov8l.trt --buildOnly --minShapes=images:1x3x640x640 --optShapes=images:4x3x640x640 --maxShapes=images:8x3x640x640 ../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8x.onnx --saveEngine=yolov8x.trt --buildOnly --minShapes=images:1x3x640x640 --optShapes=images:4x3x640x640 --maxShapes=images:8x3x640x640 # 1280 ../../../../TensorRT-8.4.2.4/bin/trtexec --onnx=yolov8x6.onnx --saveEngine=yolov8x6.trt --buildOnly --minShapes=images:1x3x1280x1280 --optShapes=images:4x3x1280x1280 --maxShapes=images:8x3x1280x1280
你将会的到例如:yolov8n.trt、yolov8s.trt、yolov8m.trt等文件。
