这个问题看起来像是在使用Python的urllib库进行网络请求时出现了连接错误。WinError 10061表示目标计算机积极拒绝连接，可能是由于防火墙或网络设置的问题导致连接失败。建议检查网络连接是否正常，以及目标计算机是否允许外部连接。另外，您可以尝试使用其他网络请求库或者尝试在不同的网络环境下进行测试。

这个错误信息表明在使用pip安装Python包的时候，连接到远程服务器获取数据的过程中发生了连接错误。可能原因是网络不稳定，或者远程服务器出现了故障。您可以尝试重新运行pip命令，或者等待一段时间后再尝试安装。如果问题持续存在，您可以尝试更换网络环境或者联系远程服务器管理员。另外，您也可以通过手动下载包文件并使用pip安装本地文件的方式来解决这个问题。

这个错误提示显示你的pip尝试连接到 https://pypi.org/simple/opencv-python/ 时失败了。这可能是因为你的网络连接存在问题，或者该网站正在维护。你可以尝试以下几种解决方案：

1. 检查你的网络连接，确保你能够正常访问互联网。
2. 暂时更换 pip 源，使用其他的源来下载 opencv-python。例如，可以使用清华大学的镜像源，命令为：`pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python`
3. 等待一段时间后再尝试下载，因为有可能该网站正在维护。
4. 手动下载 opencv-python 的安装文件，然后通过本地文件安装。可以到 https://pypi.org/project/opencv-python/#files 这个网站下载对应版本的安装文件，然后通过 `pip install <本地文件路径>` 命令进行安装。
