Windows10下Python配置Dlib

2. pip安装
3. 手动编译，setup.py安装
4. 验证安装成功

6. 总结与完整verbose

记录Windows10下用Python安装dlib的过程。

当然，安装前先要装好Anaconda并创建环境，方便后续包的管理。

conda环境管理命令

1. wheel安装

此法不支持GPU。

通过wheel可以直接安装dlib包，不需要编译等操作。

只需在wheel文件的目录中cmd执行pip install xxx.whl。

以下记录几种wheel获取途径：

dlib的19.8.1版本是最后一个官方提供wheel的版本，不过最高只支持到Python 3.6版本，Python版本不符合时会报错提示
这里有好心人分享的Python 3.9版本的wheel，安装时如提示is not a supported wheel on this platform，可参考此博客，使用pip debug --verbose，查看Compatible tags:后的内容，将文件名进行对应修改，再次pip install xxxx.whl

第三种不算是wheel方法，但结果一致，故记录在此；

先添加清华源：

conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge 
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/msys2/

随后conda install -c menpo dlib=19.20（此法对Python和dlib版本要求不严，但19.19版本测试有误，故使用19.20）

2. pip安装

可先配置CUDA环境再pip，可支持GPU。（dlib安装时会自动寻找cuda环境，在笔记本上pip测试安装时支持CUDA，待后续验证）

pip安装时，会自动安装较新的版本，但由于没有wheel，需要Visual Studio中的C++编译器，即时构建wheel。

安装Visual Studio，community社区版即可；与多数博客所讲的要求2015 update3不同，我在配置过程中使用2019版本的VS也能成功安装
安装VS的工作负荷和单个组件，以下列出dlib安装成功时的VS组件安装情况，并不保证每项都是必需的：
1. 工作负荷：
  1. C++桌面开发
  2. 通用桌面开发
2. 单个组件：
  1. C++核心功能
  2. MSBuild
  3. MSVC v142 - VS 2019 c++ arm生成工具 v14.25（此项选择最新也可）
  4. MSVC v142 - VS 2019 c++ arm64生成工具 v14.25（此项选择最新也可）
  5. MSVC v142 - VS 2019 c++ x64/86生成工具 v14.25（此项选择最新也可）
  6. 用于 v142 生成工具的C++通用windows平台（ARM64）
  7. 用于Windows的C++ Cmake工具
pip install cmake：直接命令行输入cmake测试安装是否成功，能识别此命令即可
pip install boost：有些地方提到较新的dlib不需此包，但又小又安装快捷，所以还是装上了
pip install dlib -v：重点：-v是为了观察verbose，安装失败的话寻找verbose中的error信息并解决即可（有很多warning是正常现象，且不加-v的话安装失败也会显示verbose）

3. 手动编译，setup.py安装

手动编译dlib，能使其支持GPU。（推荐优先尝试pip安装的方法，环境要求一致，并且会自动判断GPU是否可用）

参考1

参考2

如[2. pip安装](# 2. pip安装)，安装Visual Studio和相关组件，pip安装cmake和boost
下载dlib项目
在该项目根目录dlib-master下新建build文件夹（也可命令行mkdir build），并进入
在build目录下，

命令行cmake .. -DDLIB_USE_CUDA=1 -DUSE_AVX_INSTRUCTIONS=1，参数意为是否使用CUDA，是否使用CPU加速，根据实际情况设置；执行结束显示：
```
-- Found Threads: TRUE
-- C++11 activated.
-- Configuring done
-- Generating done
-- Build files have been written to: D:/Download/dlib-master/build
```

命令行cmake --build .（最后有.，一篇参考博客遗漏了），显示：

dlib.vcxproj -> D:\Download\dlib-master\build\dlib\Debug\dlib19.22.99_debug_64bit_msvc1925.lib
Building Custom Rule D:/Download/dlib-master/CMakeLists.txt

返回上级目录，命令行python setup.py install，如失败，同样寻找error并解决；成功则显示：

Processing dlib-19.22.99-py3.7-win-amd64.egg
creating d:\software\anaconda\envs\temp\lib\site-packages\dlib-19.22.99-py3.7-win-amd64.egg
Extracting dlib-19.22.99-py3.7-win-amd64.egg to d:\software\anaconda\envs\temp\lib\site-packages
Adding dlib 19.22.99 to easy-install.pth file

Installed d:\software\anaconda\envs\temp\lib\site-packages\dlib-19.22.99-py3.7-win-amd64.egg
Processing dependencies for dlib==19.22.99
Finished processing dependencies for dlib==19.22.99

4. 验证安装成功

安装成功后，可进入python测试:

(test) D:\Download\dlib-master>python
>>> import dlib
>>> dlib.__version__
'19.22.0'
>>> dlib.DLIB_USE_CUDA
False
>>>

其中dlib.DLIB_USE_CUDA输出False表示当前dlib不支持CUDA。

5. 遇到的问题

conda新建环境后，环境目录下没有包，只有一个meta文件夹：新建命令加上python或指出Python版本，如conda create -n new_env python conda create -n new_env python=3.9
安装dlib时遇到的一个error信息：error C2734: “GifAsciiTable8x8”: 如果不是外部的，则必须初始化常量对象，该问题出在Anaconda\Library\include\gif_lib.h文件的第286行，添加前缀extern表示它是外部变量即可；也有博客提到使用python setup.py install --no DLIB_GIF_SUPPORT方法，这就需要下载dlib项目，用setup.py安装（这个出问题的文件在另一台电脑上根本就不存在，很是神秘）

6. 总结与完整verbose

核心就是要安装Visual Studio及其各个组件、cmake和boost，并在安装dlib时查看报错信息，找到error加以解决。

有博客提到不需要下载完整Visual Studio，只需安装visual cpp build tools即可，但是我一直安装失败，所以放弃这种方法了。

另，不支持GPU的wheel可以直接拿来安装（Python与平台等条件都适配的情况下），支持GPU的wheel中已写入了该电脑的CUDA配置，无法直接使用。

最后贴出完整的pip安装时的verbose，以供对照（例中没有CUDA环境）。
