这个错误提示是由于你在安装 PyTorch 时使用了错误的包名。正确的包名是 "torch" 而不是 "pytorch"。你可以使用以下命令安装 PyTorch：

pip install torch torchvision

如果你已经安装了 PyTorch，可以使用以下命令卸载它：

pip uninstall pytorch

然后再重新安装一次即可。

这是一个安装dlib和face_recognition库时遇到的错误。根据错误输出，需要安装CMake才能构建dlib。你可以尝试通过以下命令安装CMake：

pip install cmake

然后再重新安装dlib和face_recognition库即可。

根据错误信息显示，你尝试安装的是名为“PyTorch”的包，但是正确的包名是“torch”。可以通过以下步骤解决这个问题：

1. 确认你要安装的 PyTorch 版本，访问官方网站或者文档，查看正确的包名和安装方法。

2. 使用正确的包名尝试重新安装 PyTorch。建议使用命令行安装，可以在终端中输入以下命令：

pip install torch

3. 如果仍然无法安装成功，可以尝试使用其他镜像源，例如清华大学镜像源：

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

希望这些方法能够帮助你解决问题。
