Error installing package(s): "pip", "wheel", "setuptools"

这个错误通常表示您的Python环境没有安装pip、wheel或setuptools包，或者这些包没有正确地安装。这些包是Python中非常重要的包，它们可以帮助您管理和安装其他第三方包。

要解决这个问题，您可以尝试以下步骤：
1. 确认您的Python版本，确保它是3.x版本。
2. 在终端或命令行中运行以下命令：`python -m ensurepip --default-pip`。这将确保您已安装pip。
3. 然后，您可以尝试使用pip来安装setuptools和wheel：`python -m pip install --upgrade setuptools wheel`。

如果您的网络连接不稳定，可以尝试使用国内镜像源来安装这些包，例如：`pip install -i https://pypi.tuna.tsinghua.edu.cn/simple <package_name>`。

这个错误是因为缺少CMake，dlib需要使用CMake进行编译。您需要先安装CMake，然后再重新安装dlib库。以下是在Windows上安装CMake和dlib的步骤：

1. 下载CMake安装程序：您可以从CMake的官方网站 https://cmake.org/download/ 下载适合您的操作系统的CMake安装程序。

2. 安装CMake：运行下载的CMake安装程序，按照提示进行安装。

3. 安装dlib库：在命令行中输入以下命令来安装dlib库：

pip install dlib

如果您已经安装了dlib库，可以使用以下命令卸载它：

pip uninstall dlib

然后再重新安装dlib库：

pip install dlib

如果您还遇到了其他问题，请参考dlib的文档或在dlib的GitHub页面上查找更多信息。

根据报错信息显示，tensorflow-gpu 软件包已被移除，请安装 "tensorflow" 而不是 "tensorflow-gpu"。这意味着您只需安装 "tensorflow" 软件包即可使用 GPU 功能。

您可以尝试使用以下命令安装 "tensorflow" 软件包：

pip install tensorflow

如果您正在使用 Anaconda，请尝试以下命令：

conda install tensorflow

请注意，安装完 "tensorflow" 后，您可以使用 GPU 进行加速，前提是您的系统具有兼容的 GPU、CUDA 和 cuDNN 版本，并正确设置了相应的环境变量。

希望这能解决您的问题！如果您有其他疑问，请随时提问。
