Error installing python dlib uder jupyrer notebook

问题

在Jupyter Notebook下，我尝试安装dlib包：

pip install dlib

我收到了以下错误：

Collecting dlib

我不理解这个错误，cmake已经安装。

看起来错误来自cmake的安装，当在命令行中尝试运行cmake --version命令时，编译器无法识别该命令：

'cmake' is not recognized as an internal or external command,
operable program or batch file.

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for dlib
ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects

I do not understand this error, cmake is already installed.

import sys
print(sys.version)
3.10.10 | packaged by Anaconda, Inc. | (main, Mar 21 2023, 18:39:17) [MSC v.1916 64 bit (AMD64)]

it seems error is coming from cmake installation , when trying cmake --version command in cmd , the command is not recognized by compiler .

C:\Users\Rayane_2>cmake --version
'cmake' is not recognized as an internal or external command,
operable program or batch file.

我解决了这个问题，以下是步骤：

  1. 检查你的Python、pip和CMake版本。 Dlib需要Python（2.7、3.5或更新版本）、pip（19.0或更新版本）和CMake（3.8或更新版本）。你可以用以下命令检查它们的版本：
  2. Python: python --version 或 python3 --version
  3. pip: pip --version 或 pip3 --version
  4. CMake: cmake --version

我重新使用了官方网站 https://cmake.org/download/ 安装了cmake。

  1. 更新pip和setuptools。 旧版本可能与dlib不兼容。使用以下命令进行更新：

  2. pip install --upgrade pip

  3. pip install --upgrade setuptools

  4. 安装Visual Studio构建工具。 如果你使用的是Windows，你需要安装Visual Studio和C++构建工具。你可以从Visual Studio网站下载它们：https://visualstudio.microsoft.com/visual-cpp-build-tools/

  5. 前往Visual Studio下载页面 https://visualstudio.microsoft.com/downloads/

  6. 在“所有下载”部分，找到“Tools for Visual Studio 2019”。点击“查看所有下载”。

  7. 在打开的页面中，找到“Build Tools for Visual Studio 2019”，并点击旁边的“下载”按钮。

  8. 运行下载的安装程序。这将打开Visual Studio安装程序。

  9. 在安装程序中，在“工作负载”下，选择“C++构建工具”。

  10. 确保在右侧至少包括以下组件：
    - MSVC v142 - VS 2019 C++ x64/x86 构建工具
    - Windows 10 SDK
    - C++用于最新v142构建工具的CMake工具（x86和x64）
    - 用于x86和x64的最新v142构建工具的C++ ATL

  11. 点击“安装”开始安装。

  12. 安装完成后，可以再次在命令行或Jupyter cell中运行以下命令：pip install dlib

  13. 导入：import dlib

英文:

I solved the problem , those are the steps:

  1. Check your Python, pip, and CMake versions. Dlib requires Python (2.7, 3.5, or newer), pip (19.0 or newer), and CMake (3.8 or newer). You can check their versions with the following commands:
  2. Python: python --version or python3 --version
  3. pip: pip --version or pip3 --version
  4. CMake: cmake --version

I installed cmake again using official website https://cmake.org/download/

  1. Update pip and setuptools. Older versions might have compatibility issues with dlib. Use the following commands to update:

  2. pip install --upgrade pip

  3. pip install --upgrade setuptools

  4. Install Visual Studio build tools. If you're using Windows, you'll need Visual Studio and C++ build tools. You can download them from the Visual Studio website: https://visualstudio.microsoft.com/visual-cpp-build-tools/

  5. Go to the Visual Studio downloads page at https://visualstudio.microsoft.com/downloads/

  6. Under the "All downloads" section, find "Tools for Visual Studio 2019". Click on "See all downloads".

  7. In the opened page, find "Build Tools for Visual Studio 2019" and click the "Download" button next to it.

  8. Run the downloaded installer. This opens the Visual Studio Installer.

  9. In the installer, under "Workloads", select "C++ build tools".

  10. Make sure to include at least the following components on the right:
    - MSVC v142 - VS 2019 C++ x64/x86 build tools
    - Windows 10 SDK
    - C++ CMake tools for Windows
    - C++ ATL for latest v142 build tools (x86 & x64)

  11. Click "Install" to start the installation.

  12. Once done , install again from cmd / jupyter cell : pip install dlib

  13. Import using : import dlib
