      Pycharm安装cv2 [python3.6]

      python解释器为Anaconda的3.6版本

      下载

      Pycharm之如何安装cv2 [python3.6]

      在这里选择对应的版本进行下载,其中参数分别为3.4.2(opencv3.4.2)、cp36(python3.6)、win_amd64(Windows64位系统),根据自己的实际情况进行调整。

      安装

      将下载的文件拷贝至E:\Anaconda3\Lib\site-packages目录下,并打开命令窗口cd 至该目录下输入如下命令进行安装:

      e:
      cd E:COWNaXvo\Anaconda3\Lib\site-packages
      pip install opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

      输出结果如下:

      E:\Anaconda3\Lib\site-packages>pip install opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

      Processing e:\anaconda3\lib\site-packages\opencv_python-3.4.2-cp36-cp36m-win_amd64.whl

      Installing collected packages: opencv-python

      Successfully installed opencv-python-3.4.2

      You are using pip version 9.0.1, however version 18.0 is available.

      You should consider upgrading via the 'python -m pip install --upgrade pip' command.

      安装成功,重启Pycharm进行引包。

      python安装cv2包报错解决

      1.在pycharm中安装cv2包报错

      ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)

      ERROR: No matching distribution found for cv2

      WARNING: You are using pip version 21.3.1; however, version 22.0.3 is available.

      You should consider upgrading via the 'C:\Program Files\Python310\python.exe -m pip install --upgrade pip' command.

      这里报错pip版本低了,需要升级pip

      2.然后去控制台升级pip,升级完去安装cv2,控制台继续报错

      ERROR: Could not find a version that satisf开发者_Python培训ies the requirement cv2 (from versions: none)

      ERROR: No matching distribution found for cv2

      解决方法:安装未成功,然后百度查找相关资料,说是压根没有cv2的包,实际上需要安装的是一个叫opencv-python的包

      pip install opencv-python

      因为网络原因,导致时间超出,出现了如下错误:
