这个错误提示表明你的Python解释器无法下载selenium库。你可以尝试以下方法来解决这个问题：

1. 确保你的网络连接正常，或者尝试更换网络环境。
2. 确保你的Python版本正确，并且使用pip来安装selenium库。你可以在终端或命令行中执行以下命令：`pip install selenium`
3. 如果你使用的是Python虚拟环境，请确保已经在正确的虚拟环境中执行安装命令。
4. 如果上述方法都不能解决问题，你可以尝试手动下载selenium库，并将其解压到Python解释器的site-packages目录中。你可以在https://pypi.org/project/selenium/ 页面中找到selenium库的下载链接。
