1. wheel安裝

此法不支持GPU。

通過wheel可以直接安裝dlib包，不需要編譯等操作。

只需在wheel文件的目錄中cmd執行pip install xxx.whl。

以下記錄幾種wheel獲取途徑：

dlib的19.8.1版本是最后一個官方提供wheel的版本，不過最高只支持到Python 3.6版本，Python版本不符合時會報錯提示
這里有好心人分享的Python 3.9版本的wheel，安裝時如提示is not a supported wheel on this platform，可參考此博客，使用pip debug --verbose，查看Compatible tags:后的內容，將文件名進行對應修改，再次pip install xxxx.whl

第三種不算是wheel方法，但結果一致，故記錄在此；

先添加清華源：

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/

隨后conda install -c menpo dlib=19.20（此法對Python和dlib版本要求不嚴，但19.19版本測試有誤，故使用19.20）

2. pip安裝

可先配置CUDA環境再pip，可支持GPU。（dlib安裝時會自動尋找cuda環境，在筆記本上pip測試安裝時支持CUDA，待后續驗證）

pip安裝時，會自動安裝較新的版本，但由於沒有wheel，需要Visual Studio中的C++編譯器，即時構建wheel。

安裝Visual Studio，community社區版即可；與多數博客所講的要求2015 update3不同，我在配置過程中使用2019版本的VS也能成功安裝
安裝VS的工作負荷和單個組件，以下列出dlib安裝成功時的VS組件安裝情況，並不保證每項都是必需的：
1. 工作負荷：
  1. C++桌面開發
  2. 通用桌面開發
2. 單個組件：
  1. C++核心功能
  2. MSBuild
  3. MSVC v142 - VS 2019 c++ arm生成工具 v14.25（此項選擇最新也可）
  4. MSVC v142 - VS 2019 c++ arm64生成工具 v14.25（此項選擇最新也可）
  5. MSVC v142 - VS 2019 c++ x64/86生成工具 v14.25（此項選擇最新也可）
  6. 用於 v142 生成工具的C++通用windows平台（ARM64）
  7. 用於Windows的C++ Cmake工具
pip install cmake：直接命令行輸入cmake測試安裝是否成功，能識別此命令即可
pip install boost：有些地方提到較新的dlib不需此包，但又小又安裝快捷，所以還是裝上了
pip install dlib -v：重點：-v是為了觀察verbose，安裝失敗的話尋找verbose中的error信息並解決即可（有很多warning是正常現象，且不加-v的話安裝失敗也會顯示verbose）

3. 手動編譯，setup.py安裝

手動編譯dlib，能使其支持GPU。（推薦優先嘗試pip安裝的方法，環境要求一致，並且會自動判斷GPU是否可用）

參考1

參考2

如[2. pip安裝](# 2. pip安裝)，安裝Visual Studio和相關組件，pip安裝cmake和boost
下載dlib項目
在該項目根目錄dlib-master下新建build文件夾（也可命令行mkdir build），並進入
在build目錄下，

命令行cmake .. -DDLIB_USE_CUDA=1 -DUSE_AVX_INSTRUCTIONS=1，參數意為是否使用CUDA，是否使用CPU加速，根據實際情況設置；執行結束顯示：
```
-- 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.，一篇參考博客遺漏了），顯示：

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

返回上級目錄，命令行python setup.py install，如失敗，同樣尋找error並解決；成功則顯示：

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

Processing dependencies for dlib==19.22.99
Finished processing dependencies for dlib==19.22.99

4. 驗證安裝成功

安裝成功后，可進入python測試:

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

其中dlib.DLIB_USE_CUDA輸出False表示當前dlib不支持CUDA。

5. 遇到的問題

conda新建環境后，環境目錄下沒有包，只有一個meta文件夾：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
安裝dlib時遇到的一個error信息：error C2734: “GifAsciiTable8x8”: 如果不是外部的，則必須初始化常量對象，該問題出在Anaconda\Library\include\gif_lib.h文件的第286行，添加前綴extern表示它是外部變量即可；也有博客提到使用python setup.py install --no DLIB_GIF_SUPPORT方法，這就需要下載dlib項目，用setup.py安裝（這個出問題的文件在另一台電腦上根本就不存在，很是神秘）

6. 總結與完整verbose

核心就是要安裝Visual Studio及其各個組件、cmake和boost，並在安裝dlib時查看報錯信息，找到error加以解決。

有博客提到不需要下載完整Visual Studio，只需安裝visual cpp build tools即可，但是我一直安裝失敗，所以放棄這種方法了。

另，不支持GPU的wheel可以直接拿來安裝（Python與平台等條件都適配的情況下），支持GPU的wheel中已寫入了該電腦的CUDA配置，無法直接使用。

最后貼出完整的pip安裝時的verbose，以供對照（例中沒有CUDA環境）。
