Windows Installation Tutorial

[masoudr]

Hi,
I've successfully installed and tested this tool on my windows 10 machine and I'm writing a simple procedure to install it. It may be useful for some people try to use this tool on a Windows machine.

IMPORTANT: Actually this project has made for Linux systems and especially dlib. In my tests, the performance of this tool in Windows 10 was about a quarter in comparison with Ubuntu built with the same specs. But I haven't seen any difference between these two in other subjects.

Read First:
The new version of dlib doesn't need Boost anymore so you can skip it. Remember that you still need to meet the following requirements.
Requirments:
(I've used this tutorial with these tools installed on Windows 10 but the newer versions may work too.)

1. Microsoft Visual Studio 2015 with C/C++ Compiler installed. (Visual C++ 2015 Build Tools didn't work for me and I got into problems in compiling dlib)
2. Boost library version 1.63 or newer. Also, you can use precompiled binaries for specific MSVC you have but I don't suggest. (I've included the compiling procedure of Boost in this tutorial)
3. Of course Python3 (I used Python3.5 x64 but the other versions may work too)
4. CMake for windows and add it to your system environment variables.

Installation:
Easy installation:
Just install dlib and face_recognition (not always on newest version):
pip install dlib and then pip install face_recognition.

Manual installation:

1. Download and install scipy and numpy+mkl (must be mkl version) packages from this link (all credits goes to Christoph Gohlke). Remember to grab correct version based on your current Python version.
2. Download Boost library source code or binary release for your current MSVC from this link.
3. If you downloaded the binary version skip to step 4 else follow these steps to compile and build Boost by yourself:
   3-1. Extract the Boost source files into C:\local\boost_1_XX_X (X means the current version of Boost you have)
   3-2. Create a system variable with these parameters:
   Name: VS140COMNTOOLS
   Value: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\ (or any path where you have installed MSVC)
   3-3. Open Developer Command Prompt for Visual Studio and go to the current directory of Boost extracted and try these commands to compile Boost:
   bootstrap
b2 -a --with-python address-model=64 toolset=msvc runtime-link=static
   3-4. If you successfully compile Boost, it should create compiled files in stage directory.
4. (If you have already compiled Boost skip this step) If you already download the binary release just extract the contents to C:\local\boost_1_XX_X
5. Grab latest version of dlib from this repo and extract it.
6. Go to dlibdirectory and open cmd and follow these commands to build dlib: (remember to replace XX with current version of Boost you have)
   set BOOST_ROOT=C:\local\boost_X_XX_X
set BOOST_LIBRARYDIR=C:\local\boost_X_XX_X\stage\lib
python setup.py install --yes USE_AVX_INSTRUCTIONS or python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA
7. Now you can use import dlib without any problem into your python script.
8. You can also check the current version of dlib with pip show dlib.
9. Now simply install face_recognition with pip install face_recognition.
10. Enjoy!

Finally, I need to say thanks to @ageitgey and @davisking for their awesome work.

[TheDogeOfTheInternet]

You don't need to manually install dlib. I was able to install it with pip (through the pip install face_recognition command) after I had Boost and CMake installed.

Which leads me to my second point; your tutorial does not mention CMake at all. I have no idea what CMake actually does, so it may not be required, but if it does have something to do with simplifying the install process, you should add it to your tutorial.

[masoudr]

@TheDogeOfTheInternet yes you are right the CMake is a must and I forgot to add it but it is just used to compile dliband Boost. I've edited my post and add it thanks.
And for your first question yes you can use pipto install it but the latest versions are always on his Github repository and website so you need to compile it by yourself. Also, you can configure your compilation.

[masoudr]

@PBShortStop Installation of CMake in windows is very simple just grab the installation file (*.msi) from this link and install it. Remember to check the "Add CMake to system path" during the installation. Then you can simply use cmake --version in command prompt.

Dear all,
I've tried several times to build dlib, but waited more than 1 hour at face_recognition.cpp without seeing any progress. I redo it several times but still get stuck there. Can you help me with it?

[runt1m33rr0r]

@BachDoXuan you need to use the visual studio 2015 compiler(msvc-14.0), 14.1 is bugged. You also need at least 2GB RAM, because face_recognition.cpp takes a lot of memory during compilation(which could be the reason it takes so long).

I use VS CE 2017, 8GB RAM laptop. I use Windows 10 Pro but the windows is not activated. I have no idea what problem I have. Can you help me to install dlib?

[masoudr]

@BachDoXuan I used MSVC-14 and haven't tested the 2017 version. Are you using the precompiled version of Boost or compiling it by yourself?
Remember that some of the steps in this tutorial are for MSVC-14 and if you want to use with other versions you need to modify them.
Could you provide the error log?

@masoudr @neutrinobomber Thank you very much for your helps. The screen doesn't have any error log. It just got stuck when building dlib at face_recognition.cpp, I waited for more than hour every time I got there. But currently when I use command "pip install face_recognition" directly, then it succeeds.

[masoudr]

@BachDoXuan You are right, you can always use pip to install this package without any further work on windows. This tutorial is for the people who wanted to build dlib from source or do some configurations to it.

This is a known problem. Visual Studio 2017 is buggy and has worse support for C++11 than Visual Studio 2015. No one has been able to find a workaround other than to use Visual Studio 2015.

@loqpa Hi,
Are you using a precompiled version of boost with MSVC14?
Try to add these system environment variables too:
VS110COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\Tools\
VS120COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\

VSSDK140Install C:\Program Files (x86)\Microsoft Visual Studio 14.0\VSSDK\
I don't know the exact cause of your problem but it seems that some of the library files are not recognized by dlib.

@masoudr Hello!
I am compiling boost by myself (following steps 3-1... 3-4) and my system environment variables were already set the way you suggested.
Tried with boost 1.63, got the same error.
Any other ideas?
By the way, i am using Anaconda python, in case it matters.

[masoudr]

@loqpa I used this method for the specified version of dependencies, so I am not sure if they work for other versions too.
As I know your problem is causing by missing some dll files on dlib's compile. I think you can try first submit your issue on dlib repository here, maybe @davisking have an answer to it and second use the exact procedure I mentioned here. I don't' know much about Anaconda try to exclude it.

[masoudr]

@loqpa If you compile dlib from the source you can always use the latest features and besides of that you can customize the compilation for specific configuration like disable/enable AVX instruction, CUDA feature, etc. I used v19.6 but newer versions would work too. You can find new features on dlib's website in here.

@hepingtao be careful while downloading scipy, numpy you have to download them x86 like others(if you want to use x86). Also python, boost and also dlib must compile on x86 also. If you did everything in an x86 compiler (or x64) there will be no error.

I had the same problem, and have solved it.
I'm using anaconda3 python3.5 and when setup.py generate install project, it get jpeg library from %Anaconda3%/envs/%your_env%/Library/lib/jpeg.lib
This jpeg.lib using by pyqt package. And there are functions, that don't agree with declspec needed by dlib.

To solve problem, switch your cmd to your virtual_env, and upgrade libjpeg from anaconda channel, e.g.:
activate my_env
conda install -c anaconda libjpeg

After that, go to your %Anaconda3%/envs/%your_env%/Library/lib/ directory and make sure, that you have exactly libjpeg.lib, then temprorary move files jpeg.lib and jpeg-static.lib to your home directory.

Now, your have true libjpeg.lib, that python's setup.py cmake catch up from %Anaconda3%/envs/%your_env%/Library/lib/.

Run python setup.py install --yes USE_AVX_INSTRUCTIONS --yes DLIB_USE_CUDA and enjoy.

Don't forget move back your 'jpeg.lib' to %Anaconda3%/envs/%your_env%/Library/lib/ directory provide for pyqt package.

Note, that your don't using virtual env, your lib directory will be %Anaconda3%/Library/lib/

Note, that your don't using virtual env, your lib directory will be %Anaconda3%/Library/lib/

Thank you for your help!
Temporarily removing jpeg.lib was enough for dlib 19.7 to compile successfully.

You guys shouldn't need to do this kind of hack to make it work. I've updated dlib's build scripts to detect the broken libjpeg in anaconda and avoid linking to it. So now you should be able to say python setup.py install and it should just work.

@mahecode I think you are using dlib with pip. This tutorial is made for compiling dlib from source and it has been tested with python 3.4+. Please post complete error log or try to compile from source.

@PBShortStop It is very strange, first make sure that there is no space in your working directory second check your python version in cmd with python --version. Are you using python 3.5? Your error is about not finding the python36.lib which is for Python 3.6. Try with the latest version of dlib like 19.7 and make sure about the version of python (boost, python and MSVC must be on the same architecture like X64 or X86 before compiling dlib).

@rjtmehta99 Hi, Currently you can install dlib and face_recognition easily with pip, but if you want to build the latest version of dlib from source, you can install it without boost, so I think there is no problem to install them on Win8.

Hey, I guys I just installed face_recognition and dlib. I am using jupyter notebook, anaconda, windows 10 and python 3.6
These are the steps I followed:

1. Download the Visual studio 15 community and don't forget to check visual c++ compiler for installation.
2. pip install dlib
3. pip install face_recognition

That's all I needed to import face_recognition in my jupyter notebook.

Finally, you can enable either SSE4 or AVX instruction use. These will make certain operations much faster (e.g. face detection). You do this using CMake's cmake-gui tool. For example, if you execute these commands you will get the cmake-gui screen:

This is incorrect. Dlib compiles just fine on visual studio 2017, so long as you have updated to a new version of visual studio 2017. Earlier versions of visual studio 2017 did not support C++11, but they fixed it in more recent versions.

Hi everyone, I also had same problem of installing dlib on Windows 10 earlier, and like @ramisha93 said, no need of visual studio and boost, also similar like @llrraa's steps.

Here are my steps:

1. Go to Links for dlib download the dlib whl (for me, I download dlib-19.8.1-cp36-cp36m-win_amd64.whl)

2. Use cmd to the whl directory

3. And pip install whl_name.whl
   (pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl for me)

4. Then you can pip install face_recognition

It works for me!
