Anaconda安装指定版本的opencv 记录

卸载已安装的软件包

打开Anaconda Prompt，并输入以下命令：

(PyTorch2) C:\Users\ADMIN>pip uninstall opencv-contrib-python
Found existing installation: opencv-contrib-python 4.10.0.84
Uninstalling opencv-contrib-python-4.10.0.84:
Would remove:
c:\users\ADMIN\anaconda3\envs\pytorch2\lib\site-packages\cv2\*
c:\users\ADMIN\anaconda3\envs\pytorch2\lib\site-packages\opencv_contrib_python-4.10.0.84.dist-info\*
Proceed (Y/n)? y
Successfully uninstalled opencv-contrib-python-4.10.0.84

 

添加清华镜像并安装指定版本的OPENCV

配置清华大学的Anaconda镜像源。打开Anaconda Prompt，并输入以下命令来添加清华镜像源：

(PyTorch2) C:\Users\ADMIN>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

(PyTorch2) C:\Users\ADMIN>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/

(PyTorch2) C:\Users\ADMIN>conda config --set show_channel_urls yes

 

(PyTorch2) C:\Users\ADMIN>conda install opencv-python==4.2.1.15 -c conda-forge

 

 

发现opencv-python安装包 有个版本 cp37 与已有的python3.9不匹配。

 

安装一个python3.7 的anaconda环境 

C:\Users\ADMIN>conda create --name env_cp37 python==3.7

(PyTorch2) C:\Users\ADMIN>conda activate env_cp37

(env_cp37) C:\Users\ADMIN>pip install D:\python_opencv3.4.2.16\opencv_python-3.4.2.16-cp37-cp37m-win_amd64.whl

 

安装   pip install opencv-contrib-python==3.4.2.16
