pycharm opencv下载

在PyCharm中下载OpenCV时，如果遇到下载超时或找不到的问题，可以尝试使用清华镜像源进行下载。可以使用以下命令来安装OpenCV：

pip install opencv-contrib-python==4.1.2 -i https://pypi.tuna.tsinghua.edu.cn/simple

如果仍然遇到超时问题，可以尝试使用以下命令：

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn opencv-python

或者直接在命令行中输入以下命令：

pip install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple/

如果以上方法仍然无法解决问题，可以尝试使用其他镜像源，比如中科大镜像源：

pip install --default-timeout=1000 --ignore-installed opencv-python -i https://pypi.mirrors.ustc.edu.cn/simple/

这些方法应该可以帮助您在PyCharm中成功下载OpenCV。
