Install opencv -- CONDA to establish a virtual environment and add the kernel of this environment in jupyter

First step ： Create a myopencv Virtual environment for

win+R -->cmd

conda create --name myopencv python=3.7

The second step ： download OpenCV-python

The download page ：https://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv

find OpenCV, Because the current python Version is 3.7, The operating system is 64 position , So download

stay cmd Activate the environment on the command line

activate myopencv

pip install D:\Anaconda3\envs\myopencv\opencv_python-4.4.0-cp37-cp37m-win_amd64.whl

After entering myopencv Of Python Environmental Science

I found that I did not install numpy

sign out Python Environmental Science , stay myopencv Installation in the environment numpy

exit()
pip install numpy

Once again into the myopencv Of Python Environmental Science

import cv2

Installation successful ！！！

sign out Python Environmental Science , View all packages included in the environment

exit()
pip list

Found no ipykernel, Installation

pip install ipykernel

Installation successful

Activate the default environment (base), View the current environment （ Yes * Is the current environment ）

activate base
conda env base

Enter to add to jupyter Of kernel Environment , Input
