安装Cmake CUDA CUDNN Opencv

Requirements

Requirements for Windows, Linux and MacOS

• CMake >= 3.18: https://cmake.org/download/
• Powershell (already installed on windows): https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell
• CUDA >= 10.2: https://developer.nvidia.com/cuda-toolkit-archive (on Linux do Post-installation Actions)
• OpenCV >= 2.4: use your preferred package manager (brew, apt), build from source using vcpkg or download from OpenCV official site (on Windows set system variable OpenCV_DIR = C:\opencv\build – where are the include and x64 folders image)
• cuDNN >= 8.0.2 https://developer.nvidia.com/rdp/cudnn-archive (on Linux follow steps described here https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#installlinux-tar , on Windows follow steps described here https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#installwindows)
• GPU with CC >= 3.0: https://en.wikipedia.org/wiki/CUDA#GPUs_supported

Install CMake

检查是有安装CMake

cmake --version

Install from APT

sudo apt update
sudo apt install cmake protobuf-compiler

Install from source

Preferred install from source codes rather than snap

sudo apt install build-essential libssl-dev

下载最新的cmake版本：https://cmake.org/download/

cd Downloads
tar -zxvf cmake-x.x.x.tar.gz
cd cmake-x-x-x
sudo ./bootstrap
sudo make
sudo make install
cmake --version

显示如下，即安装成功：

Install CUDA

wget https://developer.download.nvidia.com/compute/cuda/11.5.0/local_installers/cuda_11.5.0_495.29.05_linux.run
sudo sh cuda_11.5.0_495.29.05_linux.run

Choose CUDA toolkit only, not driver

Add path to ~/.bashrc or ~/.zshrc

# CUDA paths
export PATH=$PATH:/usr/local/cuda/bin
export LD_LIBRARY_PATH=/usr/local/cuda/lib64

Install cuDNN

Download cudnn from the download page

cd Downloads
tar -xzvf cudnn-11.5-linux-*.tgz
sudo cp cuda/include/cudnn*.h /usr/local/cuda/include 
sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

Install OpenCV

The easiest way is apt

sudo apt install libopencv-dev python3-opencv
