system

Windows10 GeForce GTX 960

python installation

Install python 3.7.7 ** Check Add Python 3.7 to PATH **

numpy installation

From the command prompt

$ pip install numpy

Incidentally update pip

$ python -m pip install --upgrade pip

Install Visual Studio Code

I want to make Visual Studio Code the default editor for Git, so install it first. The version is 1.45.1 No need for someone else with an editor

Install Git

Install Git 2.26.2 There is a screen to select the default editor, so select VS Code (default is Vim) Then proceed as it is OK

Install CMake

Install CMake 3.17.2

Visual Studio installation

Install Visual Studio 16.5 Community

Check ** python ** and ** Desktop Development ** to install

You will be asked to restart ** Restart your PC **

GPU driver update

Download and install the driver in your environment from NVIDIA Official

Graphic boards of other brands are not supported Updated to GTX960 445.87 When finished ** Restart your PC **

CUDA installation

Search and download nvidia cuda toolkit Version 10.2

Change the installation destination to directly under the C drive

Then proceed as it is

Download NVIDIA cuDNN

https://developer.nvidia.com/cudnn

Create a new account and download ** cuDNN v7.6.5 **

Move the downloaded ** zip file directly under the C drive and unzip it ** to create the `` `cuda``` folder.

Put the unzipped cuDNN related files under CUDA

`\cuda\In bincudnn64_7.dllCopy`



#### **`\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\Paste to bin`**
```c


 Similarly

#### **`\cuda\In include**cudnn.h**Copy`**
```c


#### **`\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\Paste to include`**
```c



#### **`\cuda\lib\on x64**cudnn.lib**Copy`**
```c


#### **`\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\lib\Paste to x64`**
```c


# OpenCV installation
## Clone opencv and opencv_contrib from GitHub
 Create and move the ```opencv``` directory directly under the C drive

git clone https://github.com/opencv/opencv git clone https://github.com/opencv/opencv_contrib

 Create a ``` build``` directory in the same directory

# CMake settings and build
 Start CMake and set the source code and build destination to `` `C: / opencv / opencv``` and `` `C: / opencv / build``` respectively
 ![cmake.jpg](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/644808/de0bddd6-0afe-5342-9526-7fc0c0d80f64.jpeg)


 Press ** Configure ** button to set generator and platform to `` `Visual Studio 16 2019` `` and `` `x64```

 Check `` `BUILD_opencv_world` `` in the list

 ![build_cvworld.jpg](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/644808/a9f0d836-4810-8864-c255-a51d755c2826.jpeg)

 Make sure there are no errors and press ** Generate **

# Build OpenCV in Visual Studio
 Open ** ALL_BUILD.vcxproj ** in the build folder ``` C: \ opencv \ build``` and start Visual Studio

 Change to Release mode and build ```ALL_BUILD``` and ```INSTALL``` from the right-click menu respectively

## Check the operation at the command prompt
 Start the python interpreter at the command prompt and check that openCV works

$ python

import cv2 cv2.version '4.3.0-dev'
