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 to try to use this tool on a Windows machine.

IMPORTANT: Actually, this project has been done for Linux systems, especially dlib. In my tests, the performance of this tool in Windows 10 was about a quarter compared to 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 (or newer) with C/C++ Compiler installed. (Visual C++ 2015 Build Tools didn't work for me, and I got into problems in compiling dlib)
2. Of course Python3 (I used Python3.5 x64 but the other versions may work too)
3. CMake for windows and add it to your system environment variables.
4. (ONLY FOR older versions of dlib) 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)

Installation:
Easy installation:
Just install dlib and face_recognition (not always on the 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 the 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, extract the contents to C:\local\boost_1_XX_X
5. Grab the latest version of dlib from this repo and extract it.
6. Go to dlib directory and open cmd and follow these commands to build dlib: (remember to replace XX with the 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 in your python script.
8. You can also check the current version of dlib with pip show dlib.
9. Now, 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 dlib and Boost. I've edited my post and add it thanks.
And for your first question yes you can use pip to 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.

[ageitgey]

Thanks @masoudr! I'll link it from the README.

[ageitgey]

Done! https://github.com/ageitgey/face_recognition/blob/master/README.md#installation

Thanks again!

[PBShortStop]

hello @masoudr, i want to know CMake install procedure. Thanks.

[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.

[BachDoXuan]

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).

[BachDoXuan]

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?

[BachDoXuan]

@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.

[davisking]

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]

Hey! I have a problem while following this tutorial.
My versions are:
Python 3.5.4
dlib 19.7
boost 1.65.1
(using "with cuda" and "with avx" options)

Any ideas how to fix it? I am up to trying everything you suggest:)

[masoudr]

@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\
VS110COMNTOOLS C:\Program Files (x86)\Microsoft Visual Studio 11.0\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.

[loqpa]

@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.

[Klinsman21]

Does anyone have the link to download, Microsoft Visual Studio 2015 with C / C ++ Compiler

[masoudr]

@Klinsman21 google is your friend :) try this.

[loqpa]

@masoudr what dlib version did you use? I can use precompiled version 19.4 without any problems but i am really curious about new(19.5+) cnn face_detector :)

[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.

[cmlyldz]

Can anybody help me ?

[masoudr]

@cmlyldz You are trying to compile an X86 code on X64 compiler or vice-versa. Try to use VS2015 x86 Native Tools Command Prompt to compile dlib and remember that your python architecture must be same.

[cmlyldz]

@masoudr Thanks for answer. The problem was my python but there is no problem thanks to you.

[hepingtao]

@masoudr I have also encountered exactly the same problem as @cmlyldz . And I used VS2015 x86 Native Tools Command Prompt to compile dlib, but the problem didn't go.

[masoudr]

@hepingtao Please give me more information about the exact version of your tools like python version?

[cmlyldz]

@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.

[008karan]

I have installed cmak and added to path but while installing dlib getting message to install cmak

[masoudr]

@008karan If your CMake is successfully added, you can use cmake --version in cmd to verify that. I'm not sure if the problem will exist but put your complete error log here.

[raburgos]

oh wee thats embarrassing, yet to fully wake up.. update in progress, will try the steps again after all updated

don´t worry about that! let me know if it works for you!

[akeilox]

@raburgos this works beautifully! thanks a million!
was on conda 4.8.3, open Anaconda Prompt

conda update ipykernel
conda update --all

repeat the above update till no error (took few runs for me), then run:

conda create -n face_recognition python==3.6.6 anaconda
conda activate face_recognition
pip install cmake
pip install dlib==19.8.1
pip install face_recognition
pip install opencv-contrib-python==4.1.0.25
pip install twisted

then clone the repo with git clone https://github.com/ageitgey/face_recognition.git
cd examples
face_detection ./

(that should output detected faces of pictures in that folder.

That’s great!

[Yipeng-Wang-Peter]

Thank you for your instruction! I have installed it successfully.
Does anyone know how to execute the facial recognition's command line on window 10?

Thank you.

Hi @Yipeng-Wang-Peter !

If you want to use your webcam you can try in command line (e.g: anaconda prompt, considering current path in your local file face_recognition):
.- cd examples
.- python facerec_from_webcam_faster.py

I hope this helps!

Hi, whenever I am trying to install via pip install dlib or pip install face_recognition, I am getting the following error.

However, I installed dlib manually through the github repository and on importing I am not getting any error. But on installing or importing face_recognition, I am getting the following error

@masoudr Can you please help me out

[rjkrsngh]

Hey guys! I am trying this installation on windows 10 with python 3.9. dlib and cmake got installed quite easily but while running pip3 install face_recognition, i got the following error for face_detection. As much as i can understand, it is trying to install it using the exe file which is nowhere in the system. Secondly, when i try to execute face_recognition in the cmd, it says "'face_recognition' is not recognized as an internal or external command, operable program or batch file." Can anyone help me with it?

@masoudr, could you please let me know what am i missing here?

[uestchang]

I think u can try to edit the concrete codes in an IDE such as pycharm, and if u test in IDE, u don't need to install with _.exe  file.

I haven't test the VS 2022 yet but as I know it add the C++20 support, so maybe downgrading the compiler may fix compilation issues.

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.

hi!
I am not able to install dlib from pip command.

If you want to install the dlib library, you need to install c++

[MarcioJrios]

For anyone facing errors trying to install directly on windows, there is the option of using a WSL(Windows Subsystem for Linux), wich is a native VM implementation for windows. You can install normally the API like you would in a Linux machine, then you can acess it directly through Windows using VScode with the extension "Remote -WSL"(instuctions on how to do that are on the extension description itself).

Here is an example on it working perfeclty using Flask like if i am running it locally on windows.
Hope it helps anyone with problems related to Windows usage!

Hello good people! I was wondering if the encoding becomes properly trained if there is only 1 picture of each person or does there need to be at least more than 1 or something. Thats because when i have single image of different people the encoding after training , the recognition part gives a wrong detection. But whenever i have about 3 or more images of the same person being trained on the encodings, the recognition script gives the correct detection. Any input would be hugely appreciated

@loqpa I believe that was a known problem/bug with the dlib conda package on Windows specifically and not dlib itself
